FSP Group AU-500FL 500W

This is a 500W unit with 80+ Gold efficiency certification and semi cabling. 500W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.
