SeaSonic X 750W

This is a 750W unit with 80+ Gold efficiency certification and full cabling. 750W 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 $119.99, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Seasonic backs the product through its standard warranty channels; check the listing for region-specific terms.
