Corsair RM1000e (2022) 1000W

This is a 1000W unit with 80+ Gold 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.

At $142.99 it sits in the high-end power supply bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Support and warranty service run through Corsair, with terms that vary by region.
