So far I've had 6/60 PSUs fail on me. That's a 10% failure rate, and something seems up.

When I get back to work on Monday, I'm going to crack it open and see if I can find any failed components, but has anyone else experienced failures with these PSUs? They are the ones that came bundled with the A4+ ASICs.

Thanks! I'll report my findings here after I trouble shoot them.
