How we picked and tested

The RTX 3080 is a high-end, power-hungry graphics card. Therefore, we had the bar set high while compiling this list. We sifted through tons of options to help you find the perfect PSU for your next high-end build.

Since the RTX 3080 has a TPD of 320 watts, we recommend a 750-watt PSU, which is also what NVIDIA recommends. However, the power of your PSU is determined by your components. While 750 watts is more than enough for most builds, if you are combining the RTX 3080, a powerful GPU, with a beefy CPU such as the Intel 13900K or AMD 7950x, you may require a 1000W PSU.

If you’re pairing the RTX 3080 with a Core i9 13900K, check out roundup of the best 13900K motherboards. 

As a result, we have PSU options ranging from 750 watts to 1000 watts of power output on this list. While compiling this list, we focused on the most important aspects of a good power supply while ignoring all of the marketing nonsense. We started by looking at the rating because a good certified PSU ensures good performance under both high and low loads. We also checked the power efficiency to ensure that the power supply does not raise your electricity bill.

Avoiding Performance Woes

Because the RTX 3080 is an expensive card, we made sure to test the security features of all power supplies to ensure adequate over- and under-voltage protection and surge protection. It is always good to be careful when working with a high-end system.

We made sure that the PSU performs well. We also determined whether the power supply is non-modular, semi-modular, or fully modular. Because you’re putting together a high-end system with the RTX 3080, it’s a good idea to have a fully modular power supply to reduce cable clutter. However, if you want to save money, we also included some semi-modular options.

When it comes to high-performance power supplies paired with high-end GPUs like the RTX 3080, overheating can be an issue. Because the RTX 3080 has a higher power draw, it overheats under high load. Therefore, we ensured that the PSU’s thermal efficiency was tested and that it maintained a stable temperature under heavy loads.

Furthermore, when it comes to cooling, most manufacturers install large, high RPM fans, which, while solving the heating problem, become very noisy. As a result, we chose PSUs with sound cooling systems, such as the Seasonic TX-1000 and GX-850. 

So basically, each PSU on this list has gone through a rigorous testing process. We tested the main aspects of all the PSUs while ignoring all the market fluff. To create a list of the best PSUs for the RTX 3080, we evaluated power efficiency, load regulation, thermal efficiency, modularity, and other important factors such as warranty and overall reliability.

Best Power Supply For RTX 3080 – How Much Wattage Do You Need?

The RTX 3080 is a high-power GPU, drawing a total of 320 watts. NVIDIA recommends at least a 750-watt power supply for the RTX 3080, which we also recommend. A 750-watt power supply will provide more than adequate power for most builds.

If you are just upgrading to the RTX 3080, make sure to check what CPU you have. If you do not have a power-hungry CPU, 750 watts should suffice, and if you have a lower-end CPU, you can even go down to 650 watts to save money, though we would not recommend it.

However, if you pair the RTX 3080 with a powerful CPU such as the Intel 13900K or AMD 7950X, 750 watts may not be enough, and you may need to go up to 900 watts if not 1000 watts if you have more high-end components. So, calculate the total power draw of your build and select a power supply accordingly.

To sum it up, depending on your components, yes, 750 watts is enough for most builds with the RTX 3080. Just make sure to calculate the total power requirement of your system, mainly the CPU and the GPU.

Buyer’s Guide

The power supply is one of the most essential parts of any build. It can make or break your system. Hence, it is always a good idea to research PSUs and narrow down a huge selection of choices to make the right choice. Sounds hard, right?

Our expert tech team has made a comprehensive buying guide for PSUs to make your life easier. This guide covers all the important factors related to power supplies. From ratings to cooling systems, we have you covered.

When it comes to choosing a power supply for your computer, there are several key factors to consider to ensure you get the right one for your needs. In this buying guide, we’ll go over these factors in detail to help you make an informed decision.

Wattage

The wattage of a power supply is the amount of power it can deliver to your computer’s components. It’s important to choose a power supply with a wattage rating of at least 50–100 watts higher than the power requirements of your components. This will give you some headroom for future upgrades and help ensure that your power supply doesn’t run out of juice.

Efficiency

The efficiency of a power supply ranges from 80-90%, the higher the efficiency, the lower the power loss. This means that a more efficient power supply will run cooler and be less expensive to operate in the long run. Look for a power supply with an efficiency rating of 80 Plus Bronze or higher.

The 80 Plus certification program is a voluntary certification program for power supply efficiency. PSUs are certified based on their efficiency under various loads. These certification levels are as follows:

• 80 Plus
• 80 Plus Bronze
• 80 Plus Silver
• 80 Plus Gold
• 80 Plus Platinum
• 80 Plus Titanium

The higher the certification level, the more efficient the power supply is. For example, an 80 Plus Bronze-certified power supply is more efficient than an 80 Plus-certified power supply.

Form Factor

A power supply’s “form factor” refers to its size and shape. It’s important to choose a power supply with a form factor that will fit in your computer case. The most common form factor is ATX. Most desktop computers use ATX cases. Although, there are some smaller form factors like SFX., which are generally reserved for compact builds that use a mini-ITX case.

Modularity

One additional factor to consider when buying a power supply is whether it is modular or non-modular. A modular power supply allows you to remove the cables that you don’t need, which can help improve airflow and cable management in your computer case. Non-modular power supplies, on the other hand, have all of their cables permanently attached, which can make it more difficult to manage your cables. Some power supplies offer a mix of modular and non-modular cables, which can be a good compromise.

Ultimately, the choice between a modular and a non-modular power supply is a matter of personal preference. Some people prefer the convenience and improved cable management of a modular power supply, while others prefer the lower cost and simplicity of a non-modular power supply.

Connectors

Different components require different connectors, so it’s important to make sure that the power supply has the right connectors for your components. For example, most power supplies will have a 24-pin ATX connector for the motherboard, 4-pin or 8-pin connectors for the CPU, and 6-pin or 8-pin connectors for the graphics card. Some power supplies may also include additional connectors for things like additional fans or LED lighting.

Brand

It’s important to choose a power supply from a reputable brand. Especially one that has a good track record of producing high-quality power supplies. This will help ensure that you’re getting a power supply that will last and provide reliable power to your components. For example, Seasonic earns its reputation for being the best brand for premium power supplies.

This is because Seasonic provides a 10-year warranty with most of its power supplies. They also use high-end capacitors that provide clean and ample power to any build. While Seasonic is certainly the best in class in this space, higher-end PSUs from other big names such as Corsair, MSI, and EVGA are also almost always a safe bet.

Value

Of course, price is also a factor to consider when buying a power supply. Power supplies can range from budget-friendly options that cost less than $50 to high-end models that cost over $200. As with any other component, it’s important to balance price with performance and features.

In general, it’s a good idea to choose a power supply that offers the right balance. This balance should take wattage, efficiency, and reliability into account along with value.

In summary, when buying a power supply, be sure to consider all the factors. These factors include wattage, efficiency, form factor, connectors, modularity, brand, and price. Always do your research to get a sense of the quality and reliability of the power supplies you’re considering.

The Corsair HX1200i is another one of Corsair’s premium high-wattage power supplies but this unit comes from the slightly older HX lineup. However, that does not mean that the HX1200i is not a worthy competitor in today’s market. In fact, the HX1200i is still one of the most premium power supplies in the consumer desktop space in 2022, and one can safely assume that it will continue to be for quite some time.

Compared to our top pick, the AX1600i, the HX1200i drops the total capacity of the unit to 1200 watts instead of the 1600 watts of the former. 1200 watts is still more than enough more multiple graphics cards working together in a reasonably powerful crypto-mining rig. The 1200 watt peak capacity of the HX1200i still allows it to operate in the peak efficiency window of 50-60% when several attached graphics cards are operating under load.

The HX1200i also drops down a bit to the 80+ Platinum category, although calling that a downgrade would be a bit of an exaggeration. The 80+ Platinum efficiency is only awarded to extremely premium PSUs that deliver exceptional efficiency numbers under a variety of load scenarios. It might not be as efficient as an 80+ Titanium PSU, but it is as close as one can get to 100% efficiency without completely breaking the bank.

The single 12V rail of the HX1200i is capable of carrying 88A of current which is ample for multiple crypto-mining graphics cards working in tandem. The HX1200i can deliver this power to those graphics cards through its 8 available 8-pin PCIe connectors. All these features make the HX1200i finely equipped to handle many graphics cards simultaneously, and thus make it perfectly suited to a crypto-mining rig.

All in all, the HX1200i is one of the most premium high-wattage power supplies currently available, and it is one that makes quite a bit of sense if you are looking to establish a small crypto-mining rig. It is not as over-the-top as the AX1600i but it can deliver essentially the same features at a much more reasonable price. The only downside is its relative age, which should not pose a problem unless you opt for the used market.

3. Seasonic Focus Plus 1000 Gold

A More Reasonable Choice

Pros

• 1000W Capacity for Multiple Cards
• Relatively More Affordable
• Compact Design

Cons

• Slightly Lower 12V Current Rating
• Only 80+ Gold Efficiency

309 Reviews

Seasonic is one of the finest power supply brands on the market and they serve as an OEM for many other PSU brands as well, such as Corsair. The premium units from Seasonic use extremely high-quality components that allow them to perform reliably over a long period of time, and the Focus Plus 1000 Gold is no exception. The Seasonic Focus Plus 1000 Gold is one of the more reasonable all-round choices in our list due to its competitive price tag and high-quality components and features.

The Focus Plus 1000 Gold is has a maximum wattage of 1000 watts which is enough for 2 or 3 cards working together in a mining rig. This PSU is best suited to mid-range or older cards that have lower TDPs as compared to modern cards such as the RTX 3000 series. The PSU should be able to handle 2 to 3 RX 480 or RX 580 graphics cards at once, and that can deliver decent crypto-mining performance without completely breaking the bank.

The efficiency rating is also a bit lower than the Corsair units mentioned before, but 80+ Gold efficiency is certainly nothing to scoff at. The 80+ Gold standard certainly puts this unit into the high-end premium category, and also makes it a bit more affordable than the Platinum and Titanium units. The Seasonic Focus Plus 1000 Gold makes compromises in the right places and bumping down the efficiency to 80+ Gold is one of those places that makes the most sense.

The PSU can deliver up to 83A of current on its single 12V rail and that is unexceptional if we compare it to other PSUs in the same category. However, this should certainly be enough for 2-3 midrange cards working in tandem in a small mining operation, and that is exactly what this PSU is best suited for. The Focus Plus provides six 8-pin PCIe connectors to provide this power to those cards, and it is backed by a 10-year warranty as well.

While it may not be the highest-end PSU by numbers and specs, the Seasonic Focus Plus 1000 Gold is one of the most reasonable choices for a mining PSU right now. It has enough wattage to handle a small mining operation, and is reasonably efficient as well while costing quite a bit less than the more premium options. The only reason to get the more expensive units would be if you are looking to establish a slightly bigger mining operation with more graphics cards.

4. EVGA SuperNova 1000G+

Solid EVGA Option

Pros

• Enough Wattage for Multiple GPUs
• Comparitively More Affordable
• Large 135mm Fan

Cons

• Lower 80+ Gold Efficiency
• Relatively Lower 12V Current Rating

479 Reviews

EVGA is another brand that is known for producing some high-quality, reliable power supplies. Their offerings range from ultra-budget units all the way up to extremely premium units that can handle multiple graphics cards at once. The EVGA SuperNova 1000G+ falls into the latter category as it is also one of the best PSUs that EVGA currently has for sale.

Just like the aforementioned Seasonic Focus Plus Gold, the EVGA SuperNova is a 1000 watt unit which is plenty of wattage for 2-3 graphics cards of reasonable power draw. This can be ideal for those of you who are looking to establish a small mining rig with a few cards that you might already have. Moreover, the PSU can also handle some modern cards like the RX 6000 series and the RTX 3000 series, provided that you only plan to use 2 of them in one machine.

EVGA has gone with an 80+ Gold efficiency rating which is also really solid for a PSU of this quality. Of course, it is not as efficient as some of the Platinum or Titanium-rated units out there, but 80+ Gold can certainly get the job done nicely. This PSU delivers up to 83.3A of current on its single 12V rail, which is good enough for a small mining configuration with 2-3 graphics cards of reasonable power draw. EVGA has provided six 8-pin PCIe connectors to deliver that power to the graphics cards of choice.

Backed by a ten-year warranty, the EVGA SuperNova 1000G+ is certainly a solid power supply for a Cryptocurrency mining rig in 2022. The unit is comparatively more affordable than the ones with higher efficiencies and higher wattages, but it does not compromise on the quality and the reliability of internal components. Along with the Seasonic Focus Plus, the SuperNova 1000+ is the most reasonable option for a crypto-mining PSU that offers a good price-to-performance ratio without breaking the bank.

5. Corsair RM850x

Great Value for Light Mining

Pros

• Lots of PCIe Connectors for an 850W PSU
• Much More Affordable

Cons

• Lower 850W Wattage
• Only 70A 12V Current Rating
• Better Suited for Light Mining

525 Reviews

The Corsair RM850x is one of the most popular consumer desktop power supplies on the market. This PSU belongs to the highest class of desktop power supplies and has certainly become a fan favorite among PC building enthusiasts. The RM 850x is the most popular variant of the RMx series from Corsair due to the excellent quality of its internal components and top-notch reliability.

While the RM 850x might be a solid unit for consumer desktop gaming PCs, the same cannot be said easily for mining rigs that have multiple graphics cards. In fact, the RM 850x should not be bought if you want to run 4-5 graphics cards in a moderate mining operation. This PSU is ideal for those who already have a gaming PC with this incredible unit inside, and they want to take advantage of their machine for some mining on the side. This PSU can handle a modern, fairly powerful graphics card quite easily, or you can take advantage of two graphics cards with lower power consumption for a similar experience.

The reason for this exclusive case is that the RM 850x is aimed at gaming PCs and not at mining rigs. It only has 850 Watts of total capacity, which is barely enough for one RTX 3000 series graphics card. Alternatively, you can use two older graphics cards that are less powerful, but that is the extent of the capabilities of this PSU. It is rated 80+ Gold, however, and that is certainly a nice touch. Corsair has also provided six 8-pin PCIe connectors with the RM 850x, and it is backed by a 10-year warranty as well.

The Corsair RM 850x is not a unit you should buy specifically for a mining rig. This is a very high-quality that is preferred by many high-end gaming PC builders, so it is already a common PSU among enthusiasts. If you already have this PSU in your gaming rig and want to do some light crypto-mining on the side with one or two graphics cards, then the reliability and durability of the RM 850x will not let you down.

EVGA is one of the most reliable PSU manufacturers out there. One of the best things about EVGA is that they have a lot of budget-oriented power supply products that are actually really good, therefore they are a good choice when shopping for PSUs on a budget. The EVGA 500B is one of the best budget PSUs currently available on the market and it has been a staple of entry-level builds for quite some time now.

The EVGA 500B can deliver up to 500 watts of continuous power to your build which is great for a lot of budget components. Many budget power supplies advertise a 500W rating on their product pages but that can be misleading. Most of the really cheap units can only deliver a peak wattage of 500W and are not able to sustain that wattage. Under a heavy load, those power supplies will trip and the whole computer will restart. Thankfully, that is not the case with the EVGA 500B.

This particular EVGA unit also comes with an 80+ Bronze certification which means that the unit is more efficient than many other options in this price range. The Bronze certification means that the power supply can deliver up to 85% efficiency under specific loads, and that is a very good result for a power supply in this price bracket. The 500B also comes with a decent 120mm sleeve-bearing fan that delivers low-noise operation even at high loads.

The 500B Bronze unit comes with a single 12V Rail capable of delivering up to 40A of current on it. This means that the power supply is capable of handling most graphics cards on the market under full load without any problems. 2x 8-pin PCIe connectors are also included with the unit that enables it to handle bigger graphics cards with higher power demands as well. The 500B unit also comes with all necessary protection features including OVP, UVP, OCP, OPP, and SCP. This makes the 500B a great overall choice for entry-level or even mid-range builds on a budget.

The EVGA 500B should be selected for builds with a relatively power-efficient GPU, ideally something with a TDP under 200 watts. The PSU can be ideal for builds with GPUs like the GTX 1660 Super or the RTX 2060, and can be a good match with mid-range builds on a relatively tighter budget. It is marginally more expensive than some other units, but it is well worth the price premium.

2. Thermaltake Smart 600W 80PLUS

More Capacity, Less Efficiency

Pros

• 600 Watts Capacity
• 5 Year Warranty
• Cheaper than EVGA Units
• Widely Available

Cons

• Only 80+ White Certification

1,019 Reviews

The Thermaltake Smart series is one of Thermaltake’s budget-oriented lineups of PSUs that has garnered a positive reputation with the enthusiast community due to their reliability and excellent build quality. The Thermaltake Smart 600W unit is one of the finest units in that lineup and can be a really good pairing for a budget PC build in 2022.

With 600 watts of total wattage, the Thermaltake Smart 600W is actually the highest capacity unit in our roundup. Not only is it capable of providing 600 watts of continuous power to your build, but it also has 42A of current on a single 12V rail. This makes it our recommendation for budget builds with overclocked mid-range GPUs or GPUs with a relatively high power budget. 600 Watts is more than enough for most mid-range builds with plenty of headroom for upgrades later down the line.

The Smart 600W from Thermaltake is also 80+ Certified which is a good thing but it is a bit of a step back from the EVGA 500B unit. The 80+ white certification means that the Thermaltake unit can maintain the efficiency of at least 80% under load, and while that is great news, it is a little lower than what EVGA offered with their 80+ Bronze certified 500B unit. This makes the Thermaltake Smart 600W a mixed bag in terms of value.

The Thermaltake Smart unit also comes with a single 120mm fan that is sufficiently quiet even under load and manages the thermals of the PSU nicely. 2x 8-pin PCIe connectors are included with the Smart 600W and that means that this unit can handle GPUs with much bigger power requirements. Thermaltake has gone ahead and given a 5-year warranty with the Smart 600W which is more than any other PSU in our roundup, and that definitely makes it a smart choice for a budget build.

With 600 watts of capacity, an 80 Plus certification, a 5-year warranty, and a relatively cheaper price tag than the EVGA units, the Thermaltake Smart 600W is a strong candidate for any entry-level or budget build with a decently powerful GPU. The Thermaltake Unit would have no problem handling GPUs like the RX 5500 XT or Nvidia’s GTX 1660 Ti, even at overclocked settings.

3. Corsair CX500M

Pricy but Solid Semi-Modular Option

Pros

• 80+ Bronze Efficiency
• Semi-Modular

Corsair is one of the most reputable computer hardware companies and they are renowned for their excellent power supplies, computer cases, fans, and memory kits. The CX series from Corsair is one of their budget-oriented lineups of PSUs and it has some great options for people looking for a reliable unit without breaking the bank. The CX500M is one of the best budget mid-range units from Corsair that strikes a good balance of performance, features, and price.

The Corsair CX500M is another 500 Watt unit that can provide 500 watts of continuous power to your build. Unlike some of the more sketchy offerings online, the Corsair unit delivers what it promises and it can handle any entry-level or budget mid-range build very efficiently. The 500 watts of power means that the Corsair unit is a viable option for mid-range graphics cards with TDPs under 200 watts.

One of the most unique features of the Corsair CX500M is its semi-modular interface. This is a feature that is not present in any other power supply in our roundup today and is in fact a pretty rare feature in this price bracket. Semi-modularity allows the user to only plug in those cables that you need for the system components. This allows for cleaner cable management as the amount of cables is reduced. Corsair has also included fully sleeved cables with the CX500M.

Another great feature of the Corsair CX500M is its 80+ Bronze certification. This means that despite having lower overall wattage, the Corsair unit is more efficient than the Thermaltake Smart 600W unit mentioned earlier. Corsair’s 80+ Bronze certification means that this unit can maintain efficiency of 85% under load. Corsair’s CX500M can also deliver 38A current on the single 12V rail, which is a bit less than some of the other options in this price range but is not a major problem for the graphics cards of today.

Two 8-pin PCIe connectors are also included with the Corsair CX500M, which enables this unit to handle much more power-hungry graphics cards as well. In addition to that, it comes with 0.99 APFC and all the protection features you would expect from a quality power supply, like OPP, UVP, SCP, OTP, and OVP, etc. The large 120mm fan also keeps the PSU cool while providing a quiet experience as well. The Corsair unit is very well-equipped for something that is targeted at the budget market, and it is indeed a very good quality PSU.

The CX500M is a bit more costly than some of the units on this list, but it is a really reliable 80+ Bronze certified unit that also offers a semi-modular interface. All these features make it a compelling option for a budget mid-range build in 2022.

4. EVGA 500W 80PLUS

500W Capacity on a Budget

• 2x 8-pin PCIe Connectors

Cons

• Only 80+ White Certification
• Low Efficiency

16,183 Reviews

The EVGA 500W is another budget offering from EVGA that targets entry-level builds. Unlike the EVGA 500B which was an 80+ Bronze unit, the EVGA 500W offers an 80+ White certification which is a bit of a disappointment, but considering the price, it is still a good option for an affordable build.

The 500W still offers 500 watts of continuous power which is not something we can say for most other PSUs in this price range. 500 watts will still allow the EVGA unit to run most of the graphics cards in the market today without any problem.  It will be ideal for more entry-level graphics cards like the RX 570 or GTX 1650 Super because that will leave plenty of headroom as well for a future upgrade.

When it comes to efficiency, the 500W is only able to offer an 80+ White certification which is a bit of a letdown, but considering that it still offers 500W of capacity in a really affordable package, we cannot expect much more from EVGA in this regard. For someone in need of a more efficient unit, the EVGA 500B is present for a bit of a price premium but can be considered nonetheless. The 500W also comes with a 120mm fan that keeps thermals in check, while the single 12V rail on the 500W can carry 40A of current which is plenty for the GPUs in this price class.

The 500W is more suited towards entry-level builds due to its lower efficiency, although it can still support a relatively power-hungry GPU thanks to its 2x 8-pin PCIe connectors. EVGA has offered 3 years of warranty on this unit as well, which is a nice touch at this affordable price point.

5. EVGA 430W

Recommended for Entry-Level Systems

Pros

• Can Handle iGPU Systems
• Very Affordable

Cons

• Only 430 Watts
• Only a single 8-pin PCIe Connector
• Low Efficiency

This is probably one of the cheapest branded power supply you can get for your entry-level gaming PC or HTPC. The EVGA 430W is a barebones offering from EVGA that is not designed for any kind of heavy lifting but should be enough for basic budget builds or home theater PCs. It is a very affordable unit that offers some nice features in its price bracket. The EVGA 430W should be considered for super-budget PC builds or HTPCs running on the integrated graphics of processors.

This unit can provide 430W of continuous power to the PC which is admittedly not a lot, but it is more than enough for some entry-level GPUs like the GTX 1050 which do not require an external PCIe power connector. This unit is also ideal for a home theater PC that has an iGPU or a small video card like the GT 1030. In addition to the 430W of power, the EVGA unit is 80+ certified which is a nice thing at this price point.

The EVGA 430W offers 34A of current on a single 12V rail which is plenty for entry-level GPUs. A 120mm fan cools the unit and also remains relatively quiet itself due to the low demands of the PSU. A single 8-pin PCIe connector is offered by this PSU which can handle GPUs like the GTX 1650 Super if required. It is nice to see features like sleeved cables, OVP, UVP, OCP, OPP, SCP, and OTP still offered at this entry-level segment of the market.

Overall, the EVGA 430W is not a super-powerful unit, but it may be enough if you’re building an entry-level PC. It is a great buy for someone building a budget gaming PC on a super tight budget with a GPU that does not require a PCIe connector like the GTX 1050Ti or a GTX 1650. It can also be a great buy for HTPCs running on iGPUs or small video cards. Its attractive price point and appreciable features make it a compelling option for these scenarios.

The post The 5 Best Entry-Level Budget PSUs For Gaming PCs appeared first on Appuals.

The RTX 3090 provide incredible performance gains over their respective predecessors. This is one of the biggest generational leaps we’ve seen in a while. Folks, next-gen gaming is finally here. However, let’s not give in to the hype, as there are a few things we need to look at.

The most important question on everyone’s mind right now is if they need to upgrade their power supplies. Well, if you have a 650W PSU, the short answer is yes. The RTX 3090 is quite power-hungry. But you already know that, so we’ll just skip past the formalities. Here are some of the best PSUs for RTX 3090 in 2023.

1. Fractal Design Ion+ 860W Platinum PSU

Best Overall

Pros

• Best-in-class performance
• Silent operation
• Excellent modular cables
• Tight voltage regulation
• 10-year warranty

Cons

• None worth mentioning

Max Output: 860W | Efficiency Rating: 80+ Platinum | Fully Modular: Yes | Fan Size: 140mm | PSU Size: Standard ATX

Hardware enthusiasts and veteran builders are most likely familiar with Fractal Design. However, thanks to their excellent PC cases, they have gained mainstream popularity. Their main reason for fame is the fact they focus on quality, instead of gimmicks. The Fractal Design ION+ is a prime example of that.

Now, let’s get a few things out of the way first. This is an 80+ Platinum power supply. It has 860 watts of power, along with a fully modular design. Furthermore, it has the popular Zero RPM feature build in as well. This means the fans don’t spin unless it needs to. The 140mm fan is incredibly silent as well. So yes, this is everything you’d expect from a top-tier PSU.

However, it’s not the highest-end PSU you can get. There are power supplies out there with RGB, 80 Plus Titanium efficiency, and a whole lot of gimmicks. This isn’t that type of power supply. However, it’s the best blend of performance, design, acoustics, and reliability that we’ve seen to date.

We’re also big fans of the UltraFlex cables that are incredibly flexible and easy to route. The fan has long-lasting FDB bearings. Apart from that, tight voltage regulation and ease of installation make this PSU even better. Did we mention you get an extensive 10-year warranty? Yeah, this is hands down the perfect power supply.

2. EVGA Supernova 1200 P2 80+ PSU

The Enthusiast's Pick

Pros

• Loads of power
• Great acoustic performance
• Reliable capacitors
• High-quality cables
• Lengthy warranty

Cons

• ECO mode is unreliable

As you’ve probably realized from the name, this 1200W power supply is completely overpowered for most people. In fact, it is most likely not the most practical power supply on this list. However, if you genuinely need that sort of power, this is the one to get. In all seriousness, the EVGA SuperNova 1200W PSU is an absolute powerhouse.

First off, we need to run through the specs quickly. As we said before, the EVGA Supernova 1200 P2 has 1200W of reliable power. It has an 80+ platinum efficiency, so you don’t need to be anxious about the reliability. A popular feature in power supplies is the Zero RPM mode.

EVGA also has this, but it is known as ECO mode. It’s about the same thing. However, just know that the fan curve is a bit limiting. When you need that extra juice, it can take a minute or two for the fan to kick in. Fortunately, this is an efficient power supply so you can turn off ECO mode

This power supply is fully modular. Subsequently, this means that you can put useless cables away. We always appreciate an excellent fully modular PSU. The fact the included cables are sleeved in black and made of high-quality materials make it even better.

Other things worth mentioning are the silent operation, and of course, the 100% Japanese capacitors. The fan size is your standard 140mm, and it uses double ball bearings. The 10-year warranty is undoubtedly the icing on the cake.

3. Corsair RMX Series RM750x

The Best Value

Pros

• Very competitive price
• Decent modular cables
• Lower temperatures
• Zero RPM mode

Cons

• A bit louder than others
• Not for the enthusiasts

So, we’ve talked about a couple of high-end power supplies. It’s only natural now to come down to earth a bit and be a bit modest. For most people, the Corsair RM750X is the perfect PSU. It has all of the premium features you’d expect, but the overall value is what earns it a spot on this list.

If you’re familiar with online PC hardware forums, you might think that Corsair has a bad reputation with power supplies. The issue is so overblown that we have to address it here. 99% of the time, those people are talking about the VS series of PSUs. Most of those PSUs have group voltage regulation, which makes them less reliable.

The CX, CMX, and RMX series of PSUs are miles better than the VS series. Let us prove it to you. First off, this unit has an 80+ gold certification. It has rated for low power consumption, better acoustic performance, and lower temperatures. It is tuned for low noise operation at full load. However, it is still a bit louder than the higher-end PSUs on this list.

As usual, this PSU has the popular Zero RPM fan mode built-in. The industrial-grade capacitors are Japanese, and we trust Corsair in their reliability for these. The cables are fully modular, so you can get rid of the cables you don’t need. All in all, this is an excellent power supply.

However, while 750W is enough for most people, we recommend going above that if you’re an enthusiast. Once you start adding in capture cards, more SSDs, and other components, the power consumption can start to creep up. We only say this because the RTX 3090 can creep up to an uncomfortable 500W of peak power usage.

4. CoolerMaster MasterWatt 750W Power Supply

The Utilitarian

Pros

• Great value for money
• Semi-fanless mode
• Dustproof fan bearings

Cons

• Cables feel too long
• Occasional coil whine

CoolerMaster has been surprisingly successful with its power supply units. While the enthusiasts will still go with the Seasonic or Fractal Design units, the MWE series is still excellent. CoolerMaster has done a commendable job with these PSUs, and they’re ready for next-gen GPUs.

The MasterWatt 750W Power Supply looks like it’s the best power supply for the average joe. If you’re the type of person who just upgrades every couple of years, you’re going to be fine with this power supply.  The MW 750 delivers 750W of tightly controlled power. It has an 80+ Bronze efficiency rating along with a semi-fanless mode.

The fan remains idle at 15%, which means it’s essentially at Zero RPM. The fan curve gradually increases as the load increases. CoolerMaster is one of those companies that does this better than most. Apart from that, this PSU comes with 16AWG fully modular cables. The fan has a size of 120mm with a “dustproof” LDB bearing. You also get 5 years of warranty.

All things considered, this is an excellent power supply for the average consumer. However, there are a few minor annoyances. For example, the SATA cables feel like they are longer than standard cables. This means that they are a bit hard to route. A bigger issue is that some people reported their units possibly have noticeable coil whine. Keep in mind that these reports are in the minority, but it’s something that might bother you or push you away.

Corsair earns another spot on this list with something a bit different. Every PSU we’ve talked about has the standard ATX size. As you can guess from the name, the SF750 is an SFX power supply. Some people also refer to it as a small form factor or SFF power supply. Long story short, this is one of the few small PSUs we can recommend for the RTX 3090.

The SF series happens to be one of the better options when it comes to small form factor power supplies.  The SF750 is actually an A-tier PSU. Rest assured, this is one of the most reliable SFX power supplies ever made. It has an 80+ Platinum certification, which is always good to see. This is especially true for SFX PSUs, as you’ll appreciate all the reliability you can get.

SFX PSUs often suffer from coil whine, but Corsair has managed to nail this down. Of course, under full load, it can get noticeable. Still, this is one of the few PSUs to cram this much power inside, so we just have to live with it for now. The capacitors are pure Japanese, and extremely reliable.

As usual, there are a few things to worry about. Cramming this PSU inside a small case with a 3090 is going to push temperatures up for sure. The bigger issue is how much of a premium you usually pay for a high-quality SFX power supply.  The same remains true for the SF750.
