SeaSonic Core GC 550W

This is a 550W unit with 80+ Gold efficiency certification and non-modular 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.

Its $139.00 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. Seasonic backs the product through its standard warranty channels; check the listing for region-specific terms. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
