SeaSonic Platinum 660W

A 660W unit with 80+ Platinum efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 660W covers a 220–300W GPU and a midrange CPU comfortably. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
