SeaSonic PRIME Ultra Platinum 650 650W

This is a 650W unit with 80+ Platinum efficiency certification and full 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.

Its $99.99 price tag places it squarely in mid-range territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Warranty coverage follows Seasonic's standard policy — confirm regional terms on the listing.
