Just plugged in one of my PSUs when all of a sudden the DPS power supply started sparking from the bottom ( from one of the little metal spikes on the bottom). I quickly unplugged the psu and I saw that the bottom of one of the metal spikes was burned and the top of the miner had black burn marks as well. Is the Breakout Board dead? Probably my fault for not grounding the miner in the first place, but just want to make sure before I turn it on again. Never had a problem like this before...


It's not a big deal to me as the miner is probably still intact but it's a small hassle to go out and buy another PSU if this one is indeed dead. Weird way to go out...

Those pins are the connections to the terminal strip on the other side the power sire are connected to... Pure and simple they shorted against the miners metal case. Odds are the PSU is fine and should have crowbar'd.

Um, always use an insulator under the board. Those are exposed power terminals after all...

Yeah, I didn't have much space in my current build so I plopped it up directly on the miner. Completely my fault, good thing I noticed it quickly or that could've been a total loss. Normally I would place it on the the ground but I barely have room to walk anymore Tongue


Problem solved, thread locked. Was just making sure.
