I built a mining machine with an MSI z270 Mobo, lintel Pentium processor, 1 SSD, 1 RAM, 1600w PSU, 6 PCI risers for the 1070ti's...6 1070Ti.

Upon powering it up i get an led on the board that says "VGA" according to the manual it means no GPU detected, also the HDD led does not come on (maybe that's normal before installing an OS)

I tried plunging the HDMI cable from the display into each 1070ti and also the mobo HDMI port....same issue, the VGA LED comes on and off but mobo is still on.

 
Solution
I believe you are limited based on your motherboard to the number of supported GPUs. It could also be a power issue. I'd get it running with one, then two, then three and see where you top out... In general, your PSU needs to supply at least 15AMPs per card on the 12volt rail (assuming single rail design).
