Overview

This is a 850W unit with 80+ Gold 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. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Its $222.24 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Support and warranty service run through Seasonic, with terms that vary by region.
