StarTech ATXPOW350PRO 350W

A 350W unit with 80+ efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 350W 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.

PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through StarTech, 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.
