Safe to daisy chain two ASUS ROG Strix 1070 ti on a single HX1200i rail?

[geekcryptogal]

The power supply only supports 5 GPU (and only cmes iwth 4 cables.. sucks).  I want to have six cards in the rig (both the motherboard and frame support six cards).   Not sure what to do.

Should I buy a cheap power supply for the motherboard and just run the six GPU alone off of the corsair?

The PSU cables *should* be able to handle both 8-pin connections (per line) at, or close to full load. (Which is what would be expected for a pegged 1070ti with only 1x 8-pin power connection, but we don't know exactly how much power is pulled through the slot vs. through the onboard power connector.)

However, the safer bet would be to use 1x 8-pin connection from each cable, then use 2x 6-pin to 1x 8-pin adapters to power the remaining cards, sourcing each of the 6-pin connections from a different line off the PSU. This should also give you some extra length to work with, rather than powering 2 cards directly off of the same line.

you can order pcie direct from corsair.

there are 2 kinds  type 3 and type 4

two head type 4 right here

http://www.corsair.com/en-us/type-4-sleeved-black-pci-e-cable-with-pigtail-connector-and-capacitors-for-type-4-psu

so you can access 5 x 2 = 10 plugs

btw 


1070ti's  really do well at 100 to 110 watts if they are   8 pin  150 watt tdp cards

I would not do  beyond  100 watts  on the shared wires

I run those exact components (minus the ti, mine are regular 1070s, but Asus ROG).  I cable two GPU per PCI-e cable,  then two risers per sata cable.  I've had two rigs running like this for over a year.  I was hesitant at first and checked the cables for heat frequently, and have never had an issue.  I do power limit each card to 125 watts with nvidiaInspector.

Thank you. Is Nvidia inspector like MSI Afterburner?  That's all I have installed right now.  I would love an app that shows all the info on all the graphics cards at the same time.. like temperature graphs , power usage etc.  I have no idea what nicehash does to my poor cards.. thye take control and optimize them.. hoope they aren't wearing them out.

The MSI Duke 1070ti has been running up to 75C or so.  The 3 ROG STRIX 1070 ti's I have run in low 60's to about 67.

Yes its similar, but can be used at the command line to set core and mem clocks as well as power. 

Heres a sample of my batch for nvidiaInspector:

SET GPU0=-forcePState:0,0 -setPowerTarget:0,75 -setTempTarget:0,1,70 -setFanSpeed:0,40 -setMemoryClockOffset:0,0,300 -setBaseClockOffset:0,0,50
SET GPU1=-forcePState:1,0 -setPowerTarget:1,75 -setTempTarget:1,1,70 -setFanSpeed:1,40 -setMemoryClockOffset:1,0,300 -setBaseClockOffset:1,0,50
SET GPU2=-forcePState:2,0 -setPowerTarget:2,75 -setTempTarget:2,1,70 -setFanSpeed:2,40 -setMemoryClockOffset:2,0,300 -setBaseClockOffset:2,0,50
SET GPU3=-forcePState:3,0 -setPowerTarget:3,75 -setTempTarget:3,1,70 -setFanSpeed:3,40 -setMemoryClockOffset:3,0,300 -setBaseClockOffset:3,0,50
SET GPU4=-forcePState:4,0 -setPowerTarget:4,75 -setTempTarget:4,1,70 -setFanSpeed:4,40 -setMemoryClockOffset:4,0,300 -setBaseClockOffset:4,0,50
SET GPU5=-forcePState:5,0 -setPowerTarget:5,75 -setTempTarget:5,1,70 -setFanSpeed:5,40 -setMemoryClockOffset:5,0,300 -setBaseClockOffset:5,0,50

.\Bin\nvidiaInspector\nvidiaInspector.exe %GPU0% %GPU1% %GPU2% %GPU3% %GPU4% %GPU5%

I use nvidia-smi.exe to see the graphics card stats, but its a command line utility as well.  You can find it here:

C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe

Just run it from an command prompt and it will show all the stats in one snapshot.  It can make an xml file which I parse with powershell to pull that stats I want, but just running the exe will give you the basics.
