Title: 7 out of my 10 Antminer S2's just died - Will pay Cash or BTC if you can fix Post by: grkmec on June 29, 2014, 02:15:33 PM 7 out of the 10 that I have just died. I thought maybe I threw a breaker but electrical is fine. I tried swapping power strips, power cords, etc. Very odd how 7 of them would go down within 24 hours? It is like power supply is dead in the S2.
I have unplugged every possible connection between the PSU and motherboard and reconnected: 1) One unit powered back up but never started hashing. Then tried to reboot and was dead 2) One never started again 3) One unit powered up screen was just blank and then on reboot was dead 4 & 5 & 6 & 7) didn't bother trying I am at a total loss. Have my PSU's gone bad? Should I try getting a new PSU? Would you recommend replacing with a better PSU? If so, which?

Even if you were using surge protectors they could still get damaged that way. Could have also been a surge bad enough that the protector couldn't handle it and passed it on to the hardware, especially if they were cheap ones.

I lost a couple cards when my power blew one of the phases. Title: Re: 7 out of my 10 Antminer S2's just died within 24 hours Post by: grkmec on July 02, 2014, 01:18:00 AM Anyone in the NYC / CT area? I live in Stamford, CT. I will pay good money USD or BTC if you can come fix my S2 miners.
