l0l, always restart / reset your miners first before asking help Cheesy

Fixed -- amazing what uninstalling and reinstalling a paperclip can do...

I'm no EE, but you probably had a brown out followed by a surge or perhaps a surge went through.

I lost a couple cards when my power blew one of the phases.

Sounds like you had some kind of a brown out/dirty power, if it was a PSU problem they wouldn't have all died on the same day. 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.

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?
