CoolMax ZX-500 500W

A 500W unit with 80+ efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 500W 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.

Expect to pay around $47.25, which lands it among budget 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 CoolMax, with terms that vary by region. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
