Silverstone Essential 550W

This is a 550W unit with 80+ Gold efficiency certification and semi cabling. 550W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $102.00 price tag places it squarely in mid-range territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Silverstone backs the product through its standard warranty channels; check the listing for region-specific terms. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
