AMD's Ryzen 9 3900X requires considerable amounts of power, so too does the rest of a PC build. We've rounded up some of our favorite power supply units (PSU) that offer great value and reliability.
Tried & Tested
EVGA creates some killer hardware, and its power supply range is among the most recommended by the PC community. We love the SuperNOVA P2 for its reliability, high build quality, and solid performance.
1000W PSUs are only really required when you have more than one GPU installed, as well as a power-hungry CPU and other components. This Seasonic Prime PSU is perfect for such scenarios with a beefy 12-year warranty.
Choosing the right PSU is important
As aforementioned, you should never save too much money on your PSU. It's what supplies stable power to the entire PC. If you pick up an unreliable unit from an unknown brand, you run the risk of it failing and (worst-case scenario) taking a few components — like your valuable Ryzen 9 3900X — with it.
This is why we recommend only tried and tested PSUs, like the 650W EVGA SuperNOVA P2 (opens in new tab), which may be a little on the expensive side, but you get a killer PSU that will last years and has enough capacity for a single GPU enthusiast build. This PSU also comes with a 7-year warranty.
If you're after a smarter PSU, the E500 from NZXT and Seasonic is a solid choice for those who prefer to check statistics and make sure everything is running within desired parameters. All you need is a free USB 2.0 internal header on your motherboard. A 10-year warranty comes with this PSU.
