Overview

This is a 700W unit with 80+ Titanium efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 700W covers a 220–300W GPU and a midrange CPU comfortably. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Its $375.88 price tag places it squarely in premium territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Warranty coverage follows Seasonic's standard policy — confirm regional terms on the listing.
