Overview
A 550W unit with 80+ Bronze efficiency certification and non-modular 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.
PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Seasonic's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
