Faulty unit

by Charl star_border star_border star_border star_border star

Swapped over from a Corsair HX1000i, wanted a little more headroom after changing to the 14900k. PSU lasted 22 days and failed. switched back to the Corsair and no issues. Seasonic is a solid brand so probably just got unlucky.

Best PSU Period

Handles a 16 Core Ryzen and 7900XTX with ease, rock stable.
