Overview
A 850W unit with 80+ Platinum efficiency certification and full cabling. 850W 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 $129.99, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Support and warranty service run through Seasonic, with terms that vary by region.
