FAQ

Is a 400W PSU enough for an RTX 3060?

It's the bare minimum, but we'd recommend 650W. This build peaks around 336W, and a 650W 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 RTX 3060?

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.
