Sunbeam PSU-COM680-BK-US 680W

This is a 680W unit with 80+ efficiency certification and full cabling. 680W 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.
