Rosewill SilentNight-500 500W

This is a 500W unit with 80+ Platinum efficiency certification and semi cabling. 500W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
