I have problem with two rigs of mine. Both are 8x ZOTAC GTX1070, 8 GB RAM, one with ASROCK H110 BTC+, other with Biostar TB-250+. The PSUs are three Fortron Aurum 850 Pro, one EVGA 850 GQ. The problem is mostly with Neoscrypt, when ccminer (I tried like 10 versions and intensities) starts, PSUs start to emit clicking noise and after a while the rig shuts down unexpectedly, sometimes it even trips circuit breakers. Once the PSU literally exploded, thats why I have one different PSU. When i measure the power draw, it is around 500 W for each PSU. PSUs are connected with Add2PSU, I tried to start secondary PSU only with PS_ON, but no change. Both riser and GPU is connected to one PSU.
