FSP Group AU-1200PRO 1200W

A 1200W unit with 80+ Gold efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 1200W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
