Cheapest and most efficient option - also you have room to expand.
Server PSU's are pretty much all 80+ platinum and are designed to run 24/7 365 for years unlike most domestic units.
Bear in mind you should have a 15AMP circuit
Might be a bit more power than you need though and remember these do not have the resell value or demand of a domestic unit.
Topic: 8 - 11 GPU Rig, which PSUs to choose? - page 2. (Read 1218 times)
I think better with one pay, 10 x 1060 can condone maximum 1200watt without any power limitation so a 1500 watt is more than enough or even a 1200watt
Thanks for your fast reply. What's the advantage of only 1 powerful PSU instead of just using 2?2 x 700 Watt = 1400 Watt what should also be enough, or not?
Nvidia cards do not work with PCIe splitters as far as I've seen. If you get a ASUS Prime z170-A or Pro you can probably get 7 cards working, but you'd need to likely have 2 - 850W+ PSU's in order to not fully max them. A single 1500W might work as well, but you'd likely be pushing it.
Make sure you have a 20A breaker on the circuit you use or split between two circuits.

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.
