Cooler Master MasterWatt 650W

A 650W unit with 80+ Bronze efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W covers a 220–300W GPU and a midrange CPU comfortably. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

At $99.99 it sits in the mid-range power supply bracket. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Cooler Master's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
