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?
