I ordered 4 S3+ and one of them had a crooked cap that made smoke pour out of the unit, the 2nd DOA unit just made a spark when I plugged it in. That's a 50% defect rate out of the gate! There is nothing wrong with my power supply or electrical as everyone including bitmain is suggesting over and over to me. I used a 20 amp single breaker on each G2 EVGA 1300 with just 3 miners on it with stock PCI-E connectors that worked fine on all my other S3, which should be more than enough. I ran regular S3s on this setup since June. I am sorry, but bitmain has to do something to really restore my confidence here. I can understand the S3+ going bad after a few months, but 2 of right away out of the box? Even though I have the photos as evidence, its still feels like no one believes me, it MUST have been something I have done wrong and not anyone at bitmain. Very frustrating. I am sending them back, even after they see the smoke pouring out and the spark from the other unit, they probably will still want to blame me for it.
One word - SPONDOOLIES! Israeli made, no bullshit, just works.
