When i try to add a second GPU card. NVidia GeForce GTX 1070 (EVGA GTX 1070 SC Gaming Black Ed 8GB DDR5)
And reboot the system i get a warning:    please install the psu's 4-pin power cables to the 4-pin power connector on your motherboard.    I did already 

connect the two PSU 4 pin connectors to this board. (Instructions on manual page 22 English) I use a new Power supply 1200 Watt. Darkpower Pro11 (Bequit!) 

Model.  Did reconnect the power cables. Bios is newest (P1.20)

Also new power cables. I did test all the cables all ok. I did a clear Cmos, battery and on mainboard (Jumpers)

One GPU works fine i did test all PCIe slots all work fine. Did try another 3rd GPU card. All GPUs are working. As i can use them separate.   It seems that 

this board is detecting a second card, and warns about the power while. I am running out of options. advise ?  Confused
