Hi, folks!
I'm building my 1st mining rig. The equipment arrived at last and I finally finished the 2 week long construction of my very custom frame (which I'll post about later if it proves convenient). Now I did google and did a search on Bitcointalk, but still not sure how to power everything properly.
My setup:GPU2 x Asus DUAL Nvidia 1060 3GB
1 x MSI Afterburner Nvidia 1060 3GB
1 x EVGA FTW+ Nvidia 1060 3GB
2 x MSI Afterburner AMD RX470 4GB
2 x MSI Afterburner AMD RX570 8GB
PSU2 x Corsair CS750M (Gold)
MoboASRock H110 Pro BTC+
Risers8 x risers that look like this:

I figured that using an Add2PSU circuit is a good option so I'll probably grab myself one on Monday when the stores open unless you suggest me something way better.
This is how I understand the proper way to power it all up (please correct me if I'm wrong):1. Connect the PSU #0 to the Add2PSU circuit board via Molex
2. Connect the PSU #0 to the mobo via 24-pin and maybe to other power slots on the mobo if its instruction tells me to
3. Connect the PSU #0 to the 6-pin slots on Nvidia GPUs (as, AFAIK, 1060 normally consumes a little less power than RX470 or RX570 does)
4. Connect the PSU #0 to the risers in which Nvidia GPUs are installed
5. Connect the PSU #1 to the Add2PSU circuit board via 24-pin
6. Connect the PSU #1 to the 6-pin slots on AMD GPUs
7. Connect the PSU #1 to the risers in which AMD GPUs are installed
8. Connect the PSU #0 to whatever needs power supply but doesn't have one yet
Now, the questions that I got for you: Are the steps above correct?
My risers have 6-pin, Molex, and SATA power connectors at the same time to chose from. I heard connecting via 6-pin is preferable but can't recall why so.
Problem is, after I connect 4 GPU to the PSU, I won't have any free 6-pin connectors left.
So, what's the smartest of the two: to buy some 3rd party 6-pin cords and connect the risers via 6-pin slots, or to connect them via Molex/SATA official cords I received with my PSU?
If the last option from the previous question is the smartest, then use Molex or SATA? Why?
The wiring in my apartment is of decent quality and each socket easily handles 15+ kW of equipment. BUT! There is no grounding line in my house, so the sockets don't have one either. Is that critically dangerous?
My frame is almost fully metal (except for the planks on which the risers stand those are wooden), so all the PSUs and GPUs share the same contour.
Any answer, even to just one of the questions, even a partial one, will be greatly appreciated!
