SeaSonic CORE GM 650W

A 650W unit with 80+ Gold efficiency certification and semi cabling. 650W covers a 220–300W GPU and a midrange CPU comfortably. 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.

Expect to pay around $139.00, which lands it among high-end options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. 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.
