EVGA SuperNOVA 850 GM 850W

A 850W unit with 80+ Gold efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $220.00 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Warranty coverage follows EVGA'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.
