SeaSonic CORE GX ATX 3 (2024) 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.

Its $99.99 price tag places it squarely in mid-range 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.
