SeaSonic Platinum 520W

This is a 520W unit with 80+ Platinum efficiency certification and full cabling. 520W covers mainstream builds with a modest GPU. 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.

At $158.02 it sits in the high-end power supply bracket. 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. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
