What PSU do you need for an RX 570?
The RX 570 draws up to about 150W under full load. On its own that only tells half the story — your total system power (and so the PSU you need) depends just as much on your CPU, drives and cooling. This page sizes a supply for the RX 570 paired with a Core i5-6600 / 6600K; if your parts differ, the calculator gives your exact number in seconds.
Paired with a Core i5-6600 / 6600K, this build draws about 330W at peak (150W GPU + 90W CPU + system). A 600W unit runs it at ~55% load. Absolute minimum: 400W.

FAQ
Is a 400W PSU enough for an RX 570?
It's the bare minimum, but we'd recommend 600W. This build peaks around 330W, and a 600W unit keeps it near 55% load — the efficiency sweet spot — with headroom for the GPU's transient spikes.
What efficiency rating should I get for an RX 570?
80+ Bronze or Gold. It's the best balance of price and efficiency for a build this size. Never pair a good GPU with a cheap unrated PSU.
