Corsair HX850 850W

A 850W unit with 80+ Gold efficiency certification and semi 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.
