Estimate your full-system peak draw

Quick Summary · TL;DR

For the AMD Radeon RX 7700 XT, get a 700W 80+ Gold power supply (650W minimum). The card peaks near 245W; the rest of the recommendation is headroom for your CPU and the transient spikes modern GPUs produce.

Why 700W and not less?

The AMD Radeon RX 7700 XT has a board power of about 245W, but it can spike well above that for milliseconds at a time. Add a typical gaming CPU and the rest of the system, then keep the supply in its efficient 50-80% load band, and 700W is the comfortable target. The AMD Radeon RX 7700 XT draws power through a 8-pin PCIe connector, so any quality unit with the right PCIe cables works; an ATX 3.x unit is still a nice-to-have for transient headroom.

Frequently asked questions

What power supply do I need for the AMD Radeon RX 7700 XT?

A 700W 80+ Gold unit is the recommended choice; it covers the card’s peak draw plus a transient-safe buffer and keeps the PSU in its efficient load band. 650W is the realistic minimum for a single-GPU build.

Is a 650W PSU enough for the AMD Radeon RX 7700 XT?

It can run a modest build, since the card itself peaks around 245W, but it leaves little headroom for a power-hungry CPU or transient spikes. Stepping up to 700W is the safer, quieter long-term choice.

Does the AMD Radeon RX 7700 XT need an ATX 3.0 power supply?

No — it uses standard 8-pin PCIe power, so any quality PSU with the correct PCIe cables is fine. An ATX 3.x unit simply adds extra transient headroom.
