Power supply sizing

What power supply does the AMD Radeon RX 7600 need?

The AMD Radeon RX 7600 draws 165 W on its own. Here is what that means for the supply you buy, and why the answer is not simply that number.

Recommended supply

650 W

For a complete system drawing about 320 W under load.

Where the watts go

Graphics card165 W
Processor (mid-range estimate)105 W
Board, memory and storage50 W
System under load320 W

The recommendation adds 25% over measured draw. That is not padding: a supply run near its ceiling sits in the least efficient part of its curve, and graphics cards draw in microsecond spikes well above their rated figure.
