Hi,

I am going to build an 8 - 11 GPU Rig (depends on how many cards I can get to run on an Asus Z270-A mainboard (using 1 M.2 to PCIe adapter and also 1 PCIe to 4 Port PCIe adapter, see pic).
I will use only NVIDIA 1060 (some 3 GB / some 6 GB) cards, cause others are extremely overpriced.

I would prefer to use 2 seperate PSUs, cause it's much cheaper than 1 big PSU.
Would 2 700 Watt PSUs (be quiet! Pure Power 10-CM 700W) be enough to power the whole rig?
I am planning to undervolt (65%) and overclock the cards (core +120, mem +850) and think 1 card will user 90 - 110 Watt.
If I am right, the maximum for 11 GPUs would be around 1210 Watt and then there would be some power for the rest of the system (CPU, RAM, etc.).
Or is this too less power?

If I use 2 PSUs, will I have to use a special link cable, between the PSUs or will it also work if I just connect the additional cards to PSU2?

Do you think, that these 1 PCIe to 4 port PCIe adapter will work on the Asus Z270-A mainboard? Or will even more than 1 of that adapters will work on that mainboard?

Last question:
The Asus Z270-A mainboard has 2 x M.2 slots. I will use one slot for M.2 to PCIe adapter. So can I run my system using a M.2 SSD in the second M.2 slot or is it blocked cause of the use of slot 1? I am asking, cause I did read, that only one M.2 to PCIe adapter will work on that mainboard, so I am unsure if a SSD will work in the other M.2 slot.

Also this may not be a profitable rig, profits are rapidly dropping, and you may not breakeven before profits go to under a $1 a day.
