A 400W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 400W covers mainstream builds with a modest GPU. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
