Rosewill Libertas 650W

A 650W unit with 80+ efficiency certification and full 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.

Its $44.99 price tag places it squarely in budget territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Rosewill, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
