Chieftec ATMOS 750W

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

At $265.31 it sits in the premium power supply bracket. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores.
