CoolMax ZPG-500B 500W

A 500W unit with 80+ Gold 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. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $47.25, which lands it among budget options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows CoolMax'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.
