Antec EARTHWATTS GOLD PRO 650 650W

A 650W unit with 80+ Gold efficiency certification and semi 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.

Its $148.02 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through Antec, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
