Overview

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 $445.00 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Seasonic backs the product through its standard warranty channels; check the listing for region-specific terms.
