Logisys PS550E12 550W

This is a 550W unit with 80+ efficiency certification and non-modular 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 $49.99 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. Warranty coverage follows Logisys's standard policy — confirm regional terms on the listing. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
