Logisys PS480E12 480W

This is a 480W unit with 80+ efficiency certification and non-modular cabling. 480W 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.

Expect to pay around $29.99, which lands it among budget options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through Logisys, with terms that vary by region. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
