FSP Group AU-400FL 400W

This is a 400W unit with 80+ Gold efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 400W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.
