Best power supply (PSU) for gaming Windows Central 2021

Power supply units (PSUs) are one of the most critical pieces of hardware that any PC gamer looking to build their rig should consider carefully. Without a strong enough PSU to juice up your graphics and processing, your computer won't even turn on. The amount of power (and efficiency) that you need will vary depending on how strong your other pieces of hardware are, but in general, it's good to have a powerful one in case you plan on upgrading at some point. With that in mind, we think that the Corsair RM750x is one of the best power supplies for your PC, as it offers a large amount of power and a fantastic efficiency rating for a great price.

Best overall: Corsair RM750x

The Corsair RM750x is hands down the best overall PSU on the market for most gamers. It offers 750W of power, which is more than enough for most mainstream graphics cards and processors, and it will be a perfect amount for high-end gaming rigs. Also, it has an 80 Plus Gold efficiency rating, which is one of the best efficiency ratings there is for PSUs.

Its 120mm fan does a great job of keeping the PSU cool through gaming sessions, and it does so quietly, so you don't have to deal with a lot of noise. Lastly, it's fully modular, which means that you can attach or detach cables as needed instead of having to deal with permanently attached ones.

At the end of the day, the Corsair RM750x is a fantastic PSU that combines high power with superb efficiency. It's a little pricey, but considering the high performance, it's still a great deal. Unless you happen to have an incredibly beefy dual-GPU type of PC gaming rig, this power supply will be perfect for you.


  • Excellent power amount
  • Excellent efficiency
  • Modular
  • Quiet during use


  • Not for extreme power users

Best elite pick: be quiet! Dark Power Pro 12

be quiet! Dark Power Pro 12Source: be quiet!

If you do happen to be running a ridiculous dual-GPU setup with monster graphics cards like the NVIDIA RTX 3080 or 3090, then we recommend picking yourself up a be quiet! Dark Power Pro 12. It's got 1,200W of power and an 80 Plus Titanium efficiency rating, which means that it will have no problem at all keeping even the beefiest PC rig juiced up during intensive use. Also, it's fully modular, and it's got a massive fan too. It cools efficiently and isn't loud at all, which is always a plus.

To be honest, there's no real reason to get a PSU this powerful unless you have a monster setup like the one described above. The Corsair RM750x will be perfect for most people; you should opt for the be quiet! Dark Power Pro 12 only if you really need it.

Best budget: MasterWatt 750

If you're putting together a budget gaming PC and need a budget PSU to match, then we recommend the MasterWatt 750. It has an excellent power output of 750W, but the efficiency rating of 80 Plus Bronze isn't great. However, it will be perfect to power a rig with low-to-medium specs. The PSU is only semi-modular as well, meaning you can move only some of the cables around. Thankfully, the 120mm fan is efficient for cooling and runs silently.

Overall, this PSU is for people who want to get their hands on a very affordable, low-end power supply that will serve their budget PC well. It's not recommended to get this PSU if you plan on upgrading your hardware in the near future.


  • Quiet during use
  • Very affordable


  • Not ideal for high-end builds
  • Lower efficiency
  • Only semi-modular

If you're looking to build a gaming rig that focuses on compactness, then we recommend checking out the EVGA SuperNOVA 650 GM. It's got 650W of power output and an 80 Plus Gold efficiency rating, and it's got a 93mm fan that cools pretty efficiently, but not as well as the other fans on this list do. The fan also is a little bit loud when it runs, but the PSU is fully modular. It's also very compact, which makes it perfect for fitting into smaller PC cases. It packs the power of a mid-range PSU into the size of a small budget one, and for a pretty solid price, too.


  • Compact size
  • Powerful for its size
  • Fairly affordable
  • Fully modular


  • Not strong enough for top-notch setups
  • A bit noisy

Best for Xbox One: YCCSKY Xbox One Power Supply Brick


Most PSUs are for PCs, but a lot of people forget that the original Xbox One console from 2013 had one as well. Many Xbox players who have stuck with that console over the last six years have unfortunately had to deal with Microsoft's PSU dying out on them and need a replacement to use their console again. If that's you, we recommend the YCCSKY Xbox One Power Supply Brick. It's a lot more affordable than having to go through the process of getting a new PSU from Microsoft, and it also has a better, quieter fan than the original power supply, which simply makes it better in every way.


  • Better performance than Microsoft's option
  • Less expensive than getting an official replacement


  • None!
