Zalman ZM770-XT 770W

This is a 770W unit with 80+ Bronze efficiency certification and full cabling. 770W 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.
