CoolMax CUL-650B 650W

This is a 650W unit with 80+ efficiency certification and semi cabling. 650W covers a 220–300W GPU and a midrange CPU comfortably. 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.
