FSP Group ADVAN GM 1000W

This is a 1000W unit with 80+ Gold efficiency certification and full cabling. 1000W 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 $139.99, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Warranty coverage follows FSP'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.
