SeaSonic FOCUS GX-1000 ATX 3.0 1000W

This is a 1000W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 1000W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. 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. Seasonic backs the product through its standard warranty channels; check the listing for region-specific terms.
