Corsair TX850M Gold 850W

This is 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. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
