Cooler Master MasterWatt 550 550W

A 550W unit with 80+ Bronze efficiency certification and semi cabling. 550W 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.
