Overview

A 650W unit with 80+ Platinum efficiency certification and semi cabling. 650W covers a 220–300W GPU and a midrange CPU comfortably. It uses the ATX form factor — confirm your case lists ATX support. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

At $49.99 it sits in the budget power supply bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and fold its price into your running build total. 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.
