FSP Group FSP300-57FCB 300W

A 300W unit with 80+ Gold efficiency certification and full cabling. 300W 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 $139.99 price tag places it squarely in high-end territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. FSP backs the product through its standard warranty channels; check the listing for region-specific terms.
