Corsair RM850x SHIFT 850W

A 850W unit with 80+ Gold efficiency certification and non-modular cabling. 850W 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. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Its $139.99 price tag places it squarely in high-end territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Corsair, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
