Corsair CX550F 550W

A 550W unit with 80+ Bronze efficiency certification and full 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.

Expect to pay around $150.00, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Corsair 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.
