Thermaltake Toughpower 650W

A 650W unit with 80+ Gold efficiency certification and non-modular cabling. 650W 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 $59.99, which lands it among budget options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores.
