Best Power Supplies For PC Gaming In 2022

Best Power Supplies For PC Gaming

Are you in the market for a new power supply for your gaming PC rig? If so, you’re in luck, because we’ve compiled a list of the best power supplies for gaming PCs.

Whether you’re looking for something high-end or budget-friendly, we have you covered. So, without further ado, let’s take a look at the best power supplies for PC gaming!

If you want to make sure your PC is up to snuff, the best power supply is a must.

It’s not just for gamers anymore – any build that includes high-end graphics cards or other components needs one of these beefy units in order to run smoothly with no hiccups along the way!

You may be wondering what the point of investing in a quality power supply is.

You want something that will last you, and there’s no need to buy new when this could do just fine!

But don’t worry–you can spend more if necessary without worrying about low efficiency at light loads from before thanks to modern PSUs being efficient regardless of their capacity or wattage rating (gold-rated ones have even better performance).

As of July 2020, all power supplies meeting the ATX12V v2.53 spec have to be efficient at lighter loads as well– Intel has set some low-load requirements in its newest update which states that every unit must have over 70% efficiency with 10W (<500 W capacity) or less than 2%.

This requirement is practical for those looking into purchasing an energy source for their computer system because they’re going to need one anyway!

The latest Intel processor specification includes a new requirement for low-efficiency power supplies that address the Alternative Sleep Mode (ASM), which allows ultra-fast wake from sleep modes.

This can be done with alternative processors such as Microsoft Modern Standby or other ASM compatible mainboards when writing these lines but it’s always worth being future-proofed by purchasing more durable PSUs so you don’t have any issues down the road!

Picking out the right power supply can be overwhelming, but don’t worry. We have tested dozens of them and handpicked our favorites for different builds!

1. Corsair RM750x (2021) : Best Power Supply For High-End Graphics Card


  • Manufacturer (OEM): CWT
  • Max. DC output: 750 W
  • Efficiency: 80 PLUS Gold
  • Form factor: ATX12V v2.4, EPS 2.92
  • Noise: Cybernetics A- (25-30 dBA)
  • Cooling: 140 mm Maglev fan (NR140ML)
  • Modularity: Fully modular
  • EPS connectors: 2
  • PCIe connectors: 4 (on two cables)
  • Warranty: 10 years

The industry-leading RMx line of power supplies from Corsair has been a timeframe for some time now, but it’s about to get even more competitive with the release of their new models that are set out to challenge current frontrunners like Seasonic Focus GX and XPG Core Reactor.

The new Corsair RMx range is an excellent example of what can be accomplished when you improve on something that was already good.

As it turns out, there are many things wrong with improving a system in such as case, and thankfully I never had any problems during my time testing these coolers!

The new RM750x is a big step forward in noise reduction, with its performance leading to that of the older model.

Although it will not be as silent on average due to increased fan speed and louder operation when needed, you cannot call this machine noisy because Cybernetics gave it an A-rating for low levels at 28 dBA!

The efficiency of the product is outstanding, with a slight downside under high loads.

However, this does not hold back its incredible performance during light use and off-peak times which makes it an ideal choice for anyone who needs their appliances to provide them with comfort at any time day or night!

The inclusion of a powerful fan is not only welcomed but also highly valued. It supplements the reliability under harsh conditions, even when most rifle and fluid dynamic bearing fans would give out in due time.

With two EPS cables for power distribution as well four PCIe connectors available on each side; this PSU will be able to keep your gaming system running smoothly with enough oomph leftover from handling GeForce RTX 3080 graphics cards!


  • Top-notch performance overall
  • Magnetic Levitation fan
  • Fully modular
  • Huge ten-year warranty


  • You will notice a high OCP triggering point on the minor rails
  • Fan speed profile is bad
  •  In cable capacitors 

2. Seasonic Prime Titanium TX-1000: Best 1kw Power Supply


  • Manufacturer (OEM): Seasonic
  • Max. DC output: 1000 W
  • Efficiency: 80 PLUS Titanium
  • Form factor: ATX12V v2.4, EPS 2.92
  • Noise: Cybernetics A- (25-30 dBA)
  • Cooling: 135 mm FDB Fan (HA13525M12F-Z)
  • Modularity: Fully modular
  • EPS connectors: 2
  • PCIe connectors: 6 (all on dedicated cables)
  • Warranty: 12 years

The Seasonic Prime platform is a winner among power users, starting from Gold efficiency and going all the way up to Titanium.

It has been used by several high-impact brands such as Asus with its ROG Thor 1200 Watt PSU for Antec’s legendary Signature series that are known for their top quality material construction in terms of both safety standards (fire protection) and performance capabilities when it comes down right plugging into your computer without any issues whatsoever!

Seasonic has released a trusted and well-reviewed power supply, despite its high price tag.

This is an indication that there’s no need for other brands to rush in order to satisfy customer demand because this unit will sell itself with confidence from the beginning due to long warranties like those on offer here at Seasonic!

This power supply from Seasonic is one of top quality. The soldering work and use of polymer caps as well make this device very special in its features, not to mention that it also has a bearing fan for even more durability!

The Seasonic SS-300FR is a high-performance, efficient PSU that can handle heavy loads and maintain silence while doing so.

It offers tight voltage regulation on all rails with low ripple suppression using inline caps where needed; it also holds up well under light load conditions which makes this unit perfect for when you need your system to perform at its best without being overworked or generating too much heat!

The TX-1000 has six PCIe connectors on dedicated cables which will help you avoid the use of a single cable with twoX16 card slots.

This is because some graphics cards can require an excessive amount of power to run properly, so it’s best if they are fed from separate ports instead!


  • Performs very well silently
  • Components and body build quality is top-notch
  • Fully modular
  • Huge 12-year warranty


  • You will see High OCP setting on all rails, especially the minor ones

  • Manufacturer (OEM): CWT or Great Wall
  • Max. DC output: 450 W
  • Efficiency: 80 PLUS Bronze
  • Form factor: ATX12V v2.4, EPS 2.92
  • Noise: Cybernetics A- (25-30 dBA – CWT) | Standard+ (35-40 dBA – Great Wall)
  • Cooling: 120 mm rifle bearing fan (HA1225M12F-Z [CWT] or D12SM-12 [Great Wall])
  • Modularity: No
  • EPS connectors: 1PCIe connectors: 1
  • Warranty: 5 years

The CX450 is the lowest capacity member of Corsair’s budget-oriented line. It’s manufactured by either Great Wall or CWT, and uses a distinct platform for each company to make their own models in larger volumes with lower margins than higher-end products like memory kits – which can sometimes cost as much per GB!

The only way to tell the difference between these two laptops is by looking at their RPS numbers, reference designators given to each model.

Both configurations have fixed cables in order to keep prices low and feature modern platforms that utilize LLC resonant converters with voltage regulation modules for generating minor rails as well as high-quality fans!

It is hard to find a modern platform in this price range, but Corsair does it with the CMX series.

The weirdest part about them? They use an outdated system and lower performance level than what you would expect from their brand name!

The Great Wall Corsair CX450 is more efficient than the CWT model, especially under light loads.

It also has a 5VSB rail that’s less likely to cause problems with stability and efficiency but it produces much noise due to its aggressive fan profile which can be heard from across your house!

The CWT version of the Corsair CX450 is designed to avoid tariffs in the US market and keep its price tag low.

The GW platform, also available for purchase at a similar level as mainstream builds with embedded or lower-powered graphics cards such as those used on AMD APUs/CPUs (which can’t be paired together), offers high performance per dollar ratio without sacrificing any modern capabilities – it’s an excellent choice if you’re looking for one!

The XPG Core Reactor line of PSUs are a great example of the company’s commitment to providing high-quality power supplies that stand out in comparison with other brands.

These products use Channel Well Technology’s proprietary CSE platform, which gives them an edge over competitors by limiting where these units can be purchased or replaced under warranty – only from approved channels within North America for instance!

XPG’s move to become an exclusive OEM platform provider suggests that they have serious intentions in the power supply market.

The XPG Core Reactor is an impressive Computer Power Supply. It has the strength to face off against some strong competitors, such as Corsair’s RM650x and Seasonic GX-650 units but manages to lead them all despite not being very powerful in this market historically or having people who can do their jobs properly for that matter it seems like they’ve hired away from proper companies because these days anything sounds good enough when you’re talking about the electricity going into our computers!

The Core Reactor 650 is the perfect power supply for any high-performance computer.

Not only does it produce clean, steady output but its silence makes this unit all that much more efficient with an average dBA level close to 23!

With a Gold-certified efficiency rating and reaching up to 115V compatibility–you won’t find anything better than what we’ve got here on our website today.

The fully modular cables will help in the installation process and keep your workspace organized. Speaking of compact footprints, this power supply has a small one that you can easily fit into any space!

It’s not a huge drawback, but the EPS connectors hosted on one cable can be limiting.

Usually, they should have their own dedicated power cables for lower voltage drops and enhanced safety to avoid any problems with short circuits or malfunctions in high-traffic areas where many people may plug into an outlet at once like restaurants, hotels lobby, etc.

The worthy successor to the legendary AX1500i, Flextronics’ new 16 channel digital power supplies offer cutting-edge technology and best performance that money can buy.

Thanks in part due their high efficiency as well long hold up time or excellent ripple suppression capabilities these units are not only highly reliable but also provide a rich set of features for your application needs!

The Corsair Axi1600i is one of the most powerful PSUs on today’s market, and it does not disappoint when you need power.

The fans are relaxed which means that this product will be noiseless in operation thanks to its high capacity combined with top-quality components like an FDB fan; users also have three modes they can choose from: performance mode (for those who want fast loading times or low voltage), balanced setting(which reduces Noise Level by increasing temperatures)and finally “Quiet” -a fifty percent decrease over standard volume levels without reducing overall efficiency.”


  • Top notch performance in all sections
  • Good build quality
  • Silently operates
  • Excellent software control


  • Too expensive
  • The small distance between peripheral connectors
