Overview
This is a 850W unit with 80+ Platinum efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.
Its $159.99 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through Seasonic, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
