The AMD Ryzen 7 3700X isn't the most power-hungry CPU out there, but it's always essential to invest in a good power supply unit (PSU). This collection of our favorite PSUs will provide stable power to the Ryzen 7 3700X and all other components inside your PC.


EVGA SuperNOVA P2 650

Tried & Tested

EVGA is a well-established brand within the PC community, and the company's PSU line-up are excellent additions to any build. We're big fans of the SuperNOVA P2 for its reliability, high build quality, and reliable performance.



Smart Power

NZXT makes not only cases and coolers, but also PSUs now. The E series is a smart family of PSUs, allowing you to connect them to your motherboard and observe accurate readings through NZXT's CAM app.


EVGA 500 W1


You shouldn't really spend less than $50 on a PSU unless it's a solid deal on a reliable brand. EVGA's 500W W1 is a good, solid, affordable PSU with an 80+ white certification. It's not the most efficient, but it also won't destroy your PC.


Seasonic Prime PX-1000


You likely won't require a 1000W PSU when you only have this CPU and a single GPU installed, but should you look to upgrade in the future, you'll want to have plenty of headroom to expand, and this Prime PSU from Seasonic is a good option. It also comes with a 12-year warranty.

Choosing the right PSU is important

Why you can trust Windows Central Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

It's essential to never cheap out on your PSU. This is the component responsible for supplying stable power to the entire PC. If you do not grab a PSU from a reputable brand, you run the risk of it failing at some point and (worst-case scenario) taking out a few of your valuable components. Is it better to spend an extra $20 on a better PSU or risk forking out an additional $300 to replace the GPU?

This is why you'll only find us recommending tried and tested PSUs, like the 650W EVGA SuperNOVA P2, which may be a little on the expensive side, but you get a great PSU that will last years and has enough capacity for a single GPU enthusiast build. This PSU also comes with a 7-year warranty.

For those wanting a little more from their PSU, the E500 from NZXT and Seasonic is a solid choice, allowing you 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.
