The problem with crowning the best nutrition for one is that each PC’s PSU requirements are different. Not only is wattage an important consideration, but the size of systems can vary widely, meaning there really isn’t a ‘one size fits all’ solution. That said, we’re confident you’ll find something that suits you in our shortlist.
Investing in a high-quality power supply will likely make it the longest-lasting member of your setup through years of upgrades as you turn your tower into the best gaming PC. You may not necessarily consider it the most critical part of your PC, but if the gaming CPU effectively acts as the brain, then a PSU is the heart of your setup. Think about it, even the string of cables looks like a mess of arteries and veins at a glance.
Here is the best power supply for a gaming pc in 2022:
1. Best nutrition
The best nutrition is the EVGA Supernova 850 T2.
Expect to pay $190 USD / £220.
What makes the EVGA Supernova 850 T2 a cut above most PSUs is its 80 Plus Titanium certification, which means it’s 94% efficient or higher under normal load. This means that the power supply wastes very little energy, resulting in less excess heat and lower operating temperatures.
It’s completely modular, so you only need to lay the cables needed to power your system. It’s also built with Japanese Nippon Chemi-Con capacitors, making this PSU an ever-reliable part of any setup, and it comes with a 10-year warranty should you need it. While 850W should be enough for most people, you can also find 1,000W and 1,600W versions of this power supply.
- 80 Plus Titanium certification
- 10 year warranty period
- Enough power for the latest graphics cards
|EVGA Supernova 850 T2 specifications|
|watts (W)||850 / 1,000 / 1,600|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x2) / PCIe 6+2 pin (x4) / PCIe 6 pin (x2) / SATA (x10) / Peripheral 4 pin (x4)|
|80 Plus certification||Titanium|
2. Best cheap food
The best cheap food is the Corsair VS500.
Expect to pay $62 USD / £55 GBP.
Costing just under $65, the EVGA 600 BR is undoubtedly one of the best value PSUs on the market for budget-conscious builders. Despite its lower price, this power supply doesn’t skimp on the 80 Plus Bronze certification, meaning it’s definitely not a waste.
The EVGA 600 BR should have no trouble fitting into almost all ATX PC cases, thanks to its 150mm long case which is around the standard power supply size. A three-year warranty should allay any concerns about the reliability of this power supply.
- 600W for under $65 USD
- Enough juice for an Nvidia RTX 3060 Ti
- Not modular
- Not enough power for the Nvidia RTX 3070 or higher
|EVGA 600 BR|
|Connectors||ATX 24-pin (x1) / CPU 4+4-pin (x1) / PCIe 6+2-pin (x2) / SATA (x6) / Peripherals 4-pin (x3)|
|80 Plus certification||Bronze|
3. Best 1000W power supply
The best 1,000W power supply is the Gigabyte UD1000GM PG5.
Expect to pay $190 / £202.
The Nvidia RTX 4000 series hasn’t hit the 1,000W ceiling yet, but there’s no telling what the AMD RDNA 3 series is hungry for until team red lifts the lid on the Radeon 7000 GPUs. If you don’t want your power supply to lag for years to come, you might need a monster 1000W, and the Gigabyte UD1000GM PG5 is already prepared for pretty much anything to come.
It already comes with support for the latest PCIe Gen 5 16-pin power connector, which will likely eventually power any GPU that comes our way in the future. Gigabyte claims that the power supply’s 120mm smart hydraulic bearing fan lasts 1.4x longer than a standard plain bearing on some lower-priced models. It also comes with a host of other features you’d expect from a top-tier power supply, such as 80 Plus Gold certification, a fully modular design, and a 10-year warranty.
- Native support for PCIe Gen 5 16-pin power connector
- 80 Plus Gold certification
- Completely modular
- Noisier than others on this list
|Gigabyte UD1000GM PG5|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x2) / PCIe 16 pin (x1) / PCIe 6+2 pin (x4) / SATA (x8) / Peripheral 4 pin (x3)|
|80 Plus certification||Gold|
4. Best SFX power supply
The best SFX food is the Corsair SF750.
Expect to pay $170 USD / £142.
If you’re building a system in a compact PC case then the tiny but mighty Corsair SF750 should be at the top of your list for potential power supplies to spice up your miniature setup. That said, it will also work great in a larger ATX chassis, thanks to the included SFX-to-ATX bracket.
The Corsair SF750’s ‘Zero RPM Fan Mode’ ensures that the PSU doesn’t turn on its fan until it needs to, keeping it quiet when browsing the web and kicking things into high gear when gaming. It’s also fully modular and the individually-sleeved cables make it a breeze to route them into your gaming PC. If your computer doesn’t require 750W, consider the less powerful but cheaper SF600 or SF400.
- Zero RPM fan mode keeps things quiet until the PSU is at 40% load
- Includes SFX to ATX bracket
