CoolMax CUL-850B 850W

This is a 850W unit with 80+ efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Its $64.99 price tag places it squarely in mid-range territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. CoolMax backs the product through its standard warranty channels; check the listing for region-specific terms.
