This seems far more likely. Maybe just this outlet is wired incorrectly, but at least 110Vac Seasonic units seem to work fine.

Anyways, other than 1 manufacturing problem (with a recall/replacement) with, IIRC, X-650 & X-750 Gold's when they were new, Seasonic has basically been rock solid for years. In fact, they're my go-to brand for reliable PSU's.
