Overview
This is a 550W unit with 80+ Silver efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 550W covers mainstream builds with a modest GPU. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
At $77.45 it sits in the mid-range power supply bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Support and warranty service run through Gigabyte, with terms that vary by region.
