EVGA SuperNOVA 850 G5 850W

This is a 850W unit with 80+ Gold efficiency certification and full 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. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

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 EVGA, with terms that vary by region. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
