Overview
A 650W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W covers a 220–300W GPU and a midrange CPU comfortably. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.
Its $129.99 price tag places it squarely in high-end territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. 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.
