Zalman ZM660-XT 660W

A 660W unit with 80+ Bronze efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 660W covers a 220–300W GPU and a midrange CPU comfortably. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.
