Thermaltake Toughpower XT 1375W

A 1375W unit with 80+ Gold efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 1375W 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.
