Seasonic S12III 650W Power Supply - LABS Test Report

Duration: 03:31

The Seasonic S12III 650 W is an entry level, non-modular ATX power supply. It has a simple cooling setup, and efficiency that sits on the lower end of what we expect from an 80PLUS Bronze model. It has plenty of PCIe connections, but is held back by the permanently connected cables and slightly underwhelming 5 year warranty.

We tested a single unit and it failed during our OCP testing. It seemed to fail and resume functioning a couple of times before finally completely failing to recover. This unit may be fit for use in a budget system not expected to push the power rating, but we cannot recommend it for performance builds.
