I try to use the 19 GPU model but did not get it working. May be the piece was defective but I was able to return for the 12 GPU model from BioStar. I am using only 6 GPU on it currently due to the summer heat but have no complains. In winter I was using 11 GPU on same board with 2 PSU (1200 and 1000w). The rig was fairly stable
The 19-GPU model or the ASUS B250 mining expert works fine and in my opinion works a lot better than the 12-GPU BioStar mobo. To make the 19 GPUs work you will need to have mining edition cards (nvidia p106, p104, or p102) placed on the first few PCIE rows. This is clearly stated in the manual inside the motherboard's box.
