SeaSonic VERTEX PX-1200 1200W

This is a 1200W unit with 80+ Platinum efficiency certification and full cabling. 1200W 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 $319.99, which lands it among premium options. 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.
