Enermax Revolution D.F. 650W

A 650W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W 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 $335.29 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. Warranty coverage follows Enermax's standard policy — confirm regional terms on the listing.
