The AMD Ryzen 7 3800X may not be the most power-hungry processor around, but it still requires a PSU with modest capacity. We'd still recommend a PSU with at least 500W of power for a single GPU build, but just be sure to set aside some budget to cover the cost as you really shouldn't cut corners with the power supply.
Tried & Tested
When it comes to choosing a reliable PSU for your PC, you cannot go wrong with EVGA. We're big fans of the SuperNOVA P2 for its reliability, high build quality, and performance. It's also backed by a 7-year warranty.
NZXT makes not only PC cases and AIO coolers, but also power supplies. What makes NZXT's PSU line-up even more appealing is the fact Seasonic makes them. The E series is a smart PSU, allowing you to connect it to your motherboard via USB and enjoy accurate monitoring capabilities. It also comes with a 10-year warranty.
We returned to EVGA with the 500W W1, rocking an 80+ White certification. It's not the best PSU out there, nor will it allow you to throw in a second GPU, but it's affordable without cutting corners. You only get a 3-year warranty with this PSU.
You don't require 1,000W of power with this processor, but it will leave room for upgrades and expansion in the future. If you fancy diving into overclocking and plan to upgrade at a later date, this PSU from Seasonic is an excellent choice, rocking a 12-year warranty.
Choosing the right PSU is important
Don't get the PSU wrong. You shouldn't save too much money choosing one as the barebones basic power supplies you can find for $10 will likely fail within a few years and could take a few of your components with it. Is it better to spend an extra $30 on a better PSU or risk forking out an additional $300 to replace the GPU?
For this reason, it's why you won't see us recommending a "cheap" PSU, but a more affordable one. Overall, our best pick goes to the excellent 650W EVGA SuperNOVA P2 (opens in new tab), 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.
The E500 from NZXT and Seasonic is a particular PSU for those wanting a little more from their power supply. It allows you to check accurate data 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 also comes with this PSU.
