Same issues here.  After moving to 1.3.1 EthOS my local config files for power management stopped working.  My cards all juiced up to 7 for power and they are crashing now.  Rock solid and stable with 1.3.0.  I am probably going to go back because this is a joke.

No issues with NVIDIA cards.  Only AMD cards.

You're not crazy.  The Bittrex API is super sketchy right now.  Server 500 errors, and random nonsense replies.  We are porting our API software to other exchanges because Bittrex just isn't reliable right now.  They may get theior stuff together, but it is not together right now.

I bought one of these from a Chinese reseller on Alibaba.  The power supply died and I can't find a replacement anywhere.  The P/S has no 24 pin connector.  Just a 8-pin to the PCB and then 6 6-pin connectors to the mining boards.  Now that selling miners is hard my reseller stopped offering them and won't respond to me.  I need to buy a replacement power supply jst like the one in the picture.  Can anyone point me in the right direction?
