Chieftec Vega M 750W

This is a 750W unit with 80+ Gold efficiency certification and full cabling. 750W covers a 220–300W GPU and a midrange CPU comfortably. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $164.77, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores.
