FAQ
Is a 400W PSU enough for an GTX 1660 Super?
It's the bare minimum, but we'd recommend 600W. This build peaks around 305W, 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 GTX 1660 Super?
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.
