Cooler Master MasterWatt 450W

This is a 450W unit with 80+ Bronze efficiency certification and semi cabling. 450W 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.

Expect to pay around $137.00, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Support and warranty service run through Cooler Master, with terms that vary by region.
