Advice on powering 12 GTX 1060 3GB

[guacamayo]

I just got two 760W power supplies to power a 12 GTX 1060 3GB rig. The motherboard is an ASRock H110 Pro BTC+.
The power supplies are: https://www.newegg.com/Product/Product.aspx?Item=N82E16817139042

I just realized however that the power supply looks like its a 20 pin connector in one slot labeled ATX and the other is like 10 pins. Will I be able to power the motherboard with a 20 pin plug? I was going to get a dual psu adapter so they both get the on signal at the same time but now I'm not sure if these power supplies will work for what I need.

My other issue is that it looks like I'm going to have to use one of the PCIe slots to power the CPU which means I can only power 11 GPUs. Am I correct in thinking that?

Thanks for your help

2 1000 PSU are required i have few 6gpu rigs and i needed 1200 watt psu to power them the only important thing is try to buy cooler master instead of green if you can afford it.
