SHARKOON Rebel P20 1000 1000W

This is a 1000W unit with 80+ efficiency certification and full cabling. 1000W 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.
