The Nvidia GeForce RTX 3080 is sold out everywhere on Prime Day, but that doesn't mean you can't prepare for the day it's finally available. One thing that will take a lot of prospective buyers by surprise is just how power hungry that graphics card is – you're going to need at least a 750W PSU to get the most out of it. 

Luckily, over at Newegg, a lot of the best power supplies have gone on sale, so you don't have to spend a fortune on a PSU, leaving more money in your wallet to tempt you with those inflated eBay RTX 3080 sellers. 

We've picked out the best Prime Day PSU deals on Newegg, and listed them below. Every PC power supply here has at least a power rating of 750W and an 80+ Bronze efficiency rating – though we recommend going for something with an 80+ Gold rating or better.
