Cooler Master MWE 450 450W

This is a 450W unit with 80+ efficiency certification and non-modular 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 $143.00, which lands it among high-end options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
