What PSU do you need for an RX 9070?
The RX 9070 draws up to about 220W 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 9070 paired with a Ryzen 5 9600X; if your parts differ, the calculator gives your exact number in seconds.
Paired with a Ryzen 5 9600X, this build draws about 398W at peak (220W GPU + 88W CPU + system). A 750W unit runs it at ~53% load. Absolute minimum: 500W.

FAQ
Is a 500W PSU enough for an RX 9070?
It's the bare minimum, but we'd recommend 750W. This build peaks around 398W, and a 750W 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 9070?
80+ 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.
