Well, I've got a half burned-out Seasonic X-Series 1050W Gold PSU (single 12V rail), which I know doesn't fall under your "lightly used" category (figured I'd put it out here anyway). I say 'half' burned out because 2 out of the 4 PCE-E connectors no longer work after overdrawing on an old KnC Jupiter. The rest of the PSU works great though...ran the Jupiter off of those for several more months before selling the unit.

Anyway, it's still a nice PSU...but destined for the trash unless someone wants it for a repair project or what have you. Happy to provide pics as needed.
