CoolMax ZP-1000B 1000W

This is a 1000W unit with 80+ Bronze efficiency certification and semi cabling. 1000W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. 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.

At $107.99 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 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.
