Chieftec Vita SM3 750W

This is a 750W unit with 80+ Bronze efficiency certification and semi cabling. 750W 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.
