Corsair CS550M 550W

A 550W unit with 80+ Gold 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.

Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Warranty coverage follows Corsair'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.
