Rosewill Tachyon 1200 1200W

A 1200W unit with 80+ Platinum efficiency certification and full cabling. 1200W 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.
