Antec Basiq 550W

This is a 550W unit with 80+ efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 550W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Its $118.02 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through Antec, 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.
