very good rig list
btw you do not need 8gb
4gb will do
anyway use one molex cable for two gpu
and your rig will be fine

Thanks man. well i already ordered the 8gb RAM since the one's that i was watching in youtube always uses 8gb ram.
What you mean use 1 molex cable for 2 gpu? isn't it better to use 1 pcie cable per gpu to better spread load and also not to overheat cables? can you please explain on this?

if you have enough pcie cables  use the pcie cables  to power  the risers.

12x  1070's

is 12 x 100 watts = 1200 watts   at a low tdp clock  in smos  set watts to 100

12 x 120 watts =1440 watts      at a medium tdp clock in smos set watts to 120

12 x 150 watts = 1800 watts at a high tdp clock in smos set watts to 150

you need 12 + 6 = 18 pcie cables to make it work


I suggest using 100 watt setting at first

and ending up in the 115 to 125   setting at max

once you go above the 125 watt setting  1070's tend to waste the power

This is great! thanks for the input, i'll definitely try it out. Anyway, i'm thinking if i should use SMOS or use just stay with NiceHash. Since the 8 limit GPU on windows has already been increased by the creators update then i might as well try that and do the OC and Undervolting using the Nvidia Inspector if MSI afterburn or others will not support 12GPU OC

They probably mean 2 molex on 1 strand for 2 risers.

i see. all my risers are sata powered and yes, i've been planing to use 2 on 1 strand. Thanks for clearing that up!

On such a number of power cards should be enough, even with a small margin.
The main thing is to use quality cables.

Hi Guys, i need your input on my Rig. my rig will consist of the following:

SMOS

CPU PENTIUM G4400

Motherboard ASROCK H110 Pro BTC+

RAM GSKILL 8gb DDR4

PSU 2x 2000w 95+ gold (i tried buying 2x 1650w but there are no stocks in my area!)

Dual PSU link

Ver. 7 Sata powered Risers

128Gb M.2 SSD

12x Gigabyte GTX1070 all single 8-pin

10x Fans in the Rack

I also bought WattMeter/Killwatt

Is my 2 PSU enough to power those 12 GPU? i guess i need to pay attention into daisy chaining them.

i intend to power 2 risers per VGA cable, is that okay?

Thanks in advance and looking forward.
