XClio GreatPower 550W

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

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