Thermaltake TR2 650W

This is a 650W unit with 80+ efficiency certification and full cabling. 650W covers a 220–300W GPU and a midrange CPU comfortably. 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.
