That miner is being powered with a set of the HP server psu's and I have had a few problems with the power plugs on that particular board on that miner and no matter what power supply i had on it they would get ripping hot right at the plugs going in to the board. and even changing the plugs on the power supply they would still get so ripping hot they eventually melt them selves in place and the last time it happened I had to  bust off the plug charged connectors on the board and replace them and clean up all the pins so I could finally get a good resistance free connection without them getting hot when running for awhile.      Tho I did happen to notice a tiny bit of a brownish burn on the ribbon cable the last time I had a problem with the power plugs. BUT I had assumed it was just because it was so close to one of the burn plugs that I thought it was just from that and didnt really think about the ribbon cable too much more till today when it was all burned up and melted..

So it does seem related to the burning plug issue.  BUT now im wondering if instead of it being the power plugs causing a prob with the ribbon cable as well.  Im starting to wonder it might of been the other way around and something not right with the ribbon cable from the start causing problems with the power plugs.  Because now with the new ribbon cable in place them power plugs on the board are not even getting all that warm now at the power connectors.   



I just ended up figuring out that I can borrow a replacement off of my s7 and got the s9 going again while I wait for a replacement and it seems to be working and the wire is so far staying cool.  But I'm going to watch it like a hawk all day.
