SeaSonic PRIME Ultra Gold 1000 1000W

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.

Expect to pay around $196.99, which lands it among premium options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores.
