SeaSonic Platinum 1050W

This is a 1050W unit with 80+ Platinum efficiency certification and full cabling. 1050W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. 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.

Expect to pay around $29.99, which lands it among budget options. 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.
