Best Power Supply Units for Gaming Windows Central 2019

Power Supply Units (PSUs) are one of the most important pieces of hardware that any PC gamer looking to build their own 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 what 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 Seasonic FOCUS Plus 750 Platinum is the best PSU on the market, as it offers a large amount of power and a fantastic efficiency rating for a great price.

Best Overall: Seasonic FOCUS Plus 750 Platinum

The Seasonic FOCUS Plus 750 Platinum is hands down the best overall PSU on the market. 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. In addition, it has a Focus Plus Platinum efficiency rating, which is one of the highest 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 loud 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 Seasonic FOCUS Plus 750 Platinum is a fantastic PSU that combines high power with superb efficiency. It's a little pricey, but it's actually a good deal compared to the price of some other high-end PSUs. Unless you happen to have an extremely 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


  • A little pricey
  • Not for extreme power users

Best Overall

Seasonic FOCUS Plus 750 Platinum

The PSU for U

The Seasonic FOCUS Plus 750 Platinum strikes a perfect balance between power and efficiency, making it a superb choice for most PC gamers.

Best Elite Pick: CORSAIR HX1000 Platinum

If you do happen to be running a ridiculous dual-GPU setup with monster graphics cards like the NVIDIA RTX 2080 Ti, then we recommend picking yourself up a CORSAR HX1000 Platinum. It's got 1,000W of power and an 80 Plus Platinum 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 killer 135mm fan. 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 Seasonic FOCUS Plus 750 Platinum will be perfect for most people; you should only opt for the CORSAIR HX1000 Platinum if you really need it.


  • Huge power amount
  • Awesome efficiency
  • Modular
  • Quiet during use


  • Very expensive

Best Elite Pick

CORSAIR HX1000 Platinum

The cavalry has arrived

The CORSAIR HX1000 Platinum is an expensive monster PSU that should only be opted for if you have an extremely powerful rig with dual top-notch GPUs.

Best Mid-Range: Seasonic G Series 650 Gold

The Seasonic G Series 650 Gold is a strong mid-range PSU that will be capable of powering all mid-level gaming rigs with ease. You can also use it with some high-end rigs that lean towards mid-level. The Seasonic G Series 650 Gold has a solid power output of 650W and an efficiency rating of 80 Plus Gold, which isn't as great as 80 Plus Platinum, but is still great overall. Unfortunately, the PSU is only semi-modular, which means that only some of the cables can be freely attached and detached as needed, but not all of them. Luckily, though, its 120mm cooling fan is both quiet and very capable.

This PSU is ultimately a great pick if you've got yourself a mid-level PC that you want something solid and reliable for, but you don't want to get much more PSU strength than you need or want to save a bit of money.


  • Great efficiency
  • Quiet during use
  • More affordable


  • Not strong enough for top-notch setups
  • Only semi-modular

Best Mid-Range

Seasonic G Series 650 Gold

Perfect for the average build

The Seasonic G Series 650 Gold is a more affordable, less powerful PSU that's perfect for mid-to-high level rigs.

Best Budget: CORSAIR CX550M Bronze

If you're putting together a budget gaming PC and need a budget PSU to match, than we recommend the CORSAIR CX550M Bronze. It has 550W of power output, which is lower than other options on this list, but it will be enough for low-end hardware that's found in budget PCs. Also, the efficiency rating of 80 Plus Bronze isn't great, but again, it will be good enough for the purpose of powering a rig with low specs. The PSU is only semi-modular as well. 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


  • Only strong for budget PCs
  • Lower efficiency
  • Only semi-modular

Best Budget

CORSAIR CX Series 550

Go low, save high

The CORSAIR CX Series 550 is a low-cost, low-power PSU that's ideal for people who need something for a low-spec budget gaming PC.

Best Compact: FSP Dagger 600 Gold

If you're looking to build a gaming rig that focuses on compactness, than we recommend checking out the FSP Dagger 600 Gold. It's got 600W of power output and an 80 Plus Gold efficiency rating, and it's got an 80mm 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. Plus, and this is most important, it's 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
  • Modular


  • Not strong enough for top-notch setups
  • Not quiet enough

Best Compact

FSP Dagger 600 Gold

Solid power in a small frame

The FSP Dagger 600 Gold is an excellent mini-PSU that offers good strength in a small frame and for a good price.

Best Style: Thermaltake Toughpower Grand RGB 750 Gold

The Thermaltake Toughpower Grand RGB 750 Gold is a stylish-looking PSU that offers high-end power similar to the Seasonic FOCUS Plus 750 Platinum, but trades some efficiency for snazzy RGB lighting. It's got 750W of power output and a 80 Plus Gold efficiency rating, which is nearly as good as the Seasonic FOCUS Plus 750 Platinum, but not quite. This is due to the fact that the Seasonic FOCUS Plus 750 Platinum comes with a Platinum efficiency rating, which is better than Gold.

The Thermaltake Toughpower Grand RGB 750 Gold does have a bigger fan at 140mm, but unfortunately, it's a bit noisy. This is perhaps to be expected due to the RGB lights, but it's a little annoying regardless. Thankfully, the PSU is fully modular, and also this power supply costs a bit less than others on this list.

Overall, if you're okay with trading some efficiency and quieter performance for a more stylish look and a lower price, than the Thermaltake Toughpower Grand RGB 750 Gold is an excellent PSU.


  • Excellent power amount
  • Great efficiency
  • Modular
  • RGB lighting


  • A little pricey

Best Style

Thermaltake Toughpower Grand RGB 750 Gold

Style and substance together

The Thermaltake Toughpower Grand RGB 750 Gold is an excellent PSU that isn't as efficient or quiet as the higher-tier options on this list.

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 in order 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 then getting an official replacement


  • None!

Best for Xbox One

YCCSKY Xbox One Power Brick

Better in every way

The YCCSKY Xbox One Power Brick is the most effective and least expensive way to replace your faulty Xbox One PSU.

Bottom line

Ultimately, all of these different PSUs offer something different, and you're sure to find one in this list that suits your wants and/or needs. Overall, you're going to want to spend money on a quality PSU. Without power, your PC is basically useless, so if you have a few extra bucks, put it into the PSU purchase.

In general, though, we think that the Seasonic FOCUS Plus 750 Platinum is the best PSU on the list due to the fact it combines excellent power output with supreme efficiency and a great price. If you're a person putting together a competent PC gaming setup and want something that can effectively power it through intensive game sessions, it doesn't really get much better then the Seasonic FOCUS Plus 750 Platinum.
