Sorry to hear this, guess all it's unsalvageable, even the monitor, right?
I've had 4 cables breaking down due to storms and others, two taking the PSU with them, two of them were 10kw, 400v which barely showed any sign apart from the burnt bottom of the 5 pins, they didn't make any collateral victims, the other two were standard one PSU that was also burned just a bit, and one that really took some damage as the plastic was melted completely inside the socket so I had to effectively cut the cable with a bolt cutter. before throwing it.
Never had one explode like this to date, nor do I recall seeing one.
The monitor is dead. The minute I plug it into anything else it trips the circuit breaker with what I guess is a dead short.
I have not tested the miner yet. It's on the to do list in the next couple of days, but I want to be sure I have a block of time to deal with it if I have to move / test hash boards.
The cables from the PSU to the miner don't look burnt but we all know that does not mean anything.
