H110+ BTC randomly shuts down

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi All 

Recently started building out my mining rig and have come across some issues and hoping somebody can help.

Spec: 

Asrock H110+ Pro BTC MoBo
Intel Celeron G3930 CPU
Windows 10 Pro - unregistered
2 x 4GB Corsair Value Select DDR4 Ram
Samsung 850 SSD 256gb 
550w PSU - for MoBo and SSD only
2 x HP Server PSU 1200w 
2 x Breakout Boards 
6 x ASUS 1080ti Strix GPU 

I£�ve installed all GPU£�s one by one, and has been all good. Eventually it will house 8 x 1080ti and 2 x ASUS AMD RX5700xt. 

All the GPU£�s and risers (6 GPU and 6 risers) are equally  distributed among the 2 x 1200 watt server PSU. Everything boots up fine, all the GPU£�s are all showing on device manager and even are able to benchmark/partially start mining on NiceHash. 

However after about 15 minutes of being on, it completely shuts down. Initially thought it was a power supply issue, so ensured there is nothing connected to the Mobo PSU and moved all GPU£�s to the HP server PSU, however still no luck. The temperatures on the GPU and CPU barely reach about 50 degrees so it can£�t be a temp issue shut down. 

Any help would be great. 

Thank you
