LEPA B550-SA 550W

This is a 550W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 550W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.
