EVGA 750 B3 850W

This is a 850W unit with 80+ Bronze 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.
