SeaSonic PRIME Ultra Platinum 1000 1000W

A 1000W unit with 80+ Platinum 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.

At $269.99 it sits in the premium power supply bracket. 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.
