Does anyone know if you can mine Verge on the SMoS in Headless mode?
Love using it for ZenCash, but I'm looking to diversify.

Thanks.

I have a very similar setup, I'll share where I'm at after tweaking and following the advice of folks here.
I'm suggesting you change yours, just offering up what works for me in SimpleMiner.

Currently, I'm set to +200 core, +700 mem, 126w, 70 for temp, and 52% Fan Speed.
With that, I'm no averaging 510-515 Sols/s per card. I have three EVGA 1070 Ti FTW2's running on an EVGA 1000w SuperNova Platinum P2.
It's dead quiet and running perfectly between 57-40 Celsius per card.

I love to get advice from someone who knows the research!

Took your info and found a great page with the specs on most connectors http://www.playtool.com/pages/psuconnectors/connectors.html.

Looking at the back of the EVGA SuperNova P2 1000w:

Each of the VGA's are 8-pin out (rated at 336 watts per) = so splitting should be 168 watts per split (I called EVGA and they confirmed at least 300 watt per VGA output).
So I'm probably safe on a Y-Splitter keeping less than 160 watts per (and I'm at 126 max).

For the riser you are dead on, SATA is really a bad idea.
That being said, each SATA/PERF port puts out a max 75 watts (interchangeable) so theoretically, each port (4 SATA/2 PERF) 6-pin connector would support a PCI-e riser.
I could get 6-pin to Molex connectors and 'probably' be ok.

The final issue is total wattage, and my question to anyone who knows.
If a card is limited to 126 watts (using SimpleMiner), where does the power for each card come from?
Is it a mix from VGA and the PCI-e riser? Something like 100 watts VGA and 26 watts from PCI-e riser?

Or, is the power to the card considered from the VGA connector, and they PCI-e is separate power.
If they are separate, then I'm doomed with a 1kw PSU.
That would be 780 watts (230x6) for VGA + 450 watts (75x6).

Can anyone confirm if the total GPU card power is split between the PCI-e and VGA, or are they unique and separate?

I'd like to go the PSU route, but stuck with this EVGA 1000w P2 until I can upgrade.

So I think for providing power to the cards - a 6-pin to 6+2 cable is the answer - then I can get the extra power cables.
The remaining issue is how to get power to all the Risers. If the PERF (peripherals) output on the PS will power a riser, then I have 4 SATA and 2 PERF.

Is there any reason to believe that 2 SATA to MOLEX cables can't run from one SATA cable to PS?
Then I can run two PCI-E risers off of 1 SATA PS connection.

Thanks both for answering (I've set my current rig based on reading several of your posts @QuintLeo).
I've got each set to +200, +700, 126w, 70 for temp, and 52% Fan Speed (Averaging 510 Sols/s per card thanks to you!)

Checked again. Looks like the FTW2 has (2) 8-pin (6+2) on each 1070 ti.


So couldn't I use PCI-E Dual 8-Pin (6+2 Pin) Y-Splitter to each card?
Something like this: https://www.amazon.com/PCI-Express-Y-Splitter-Adapter-Converter-Gaming/dp/B004PBJARO

Total power would not exceed 756watts.
Is there a max wattage on each VGA out of the EVGA 1000 P2?

@toptek, the SATA splitters offer three outputs - what is the issue with 2 cards per SATA output on PS?

That's what I thought, but if you watch VoskCoin, he uses one 1000 watt EVGA Gold to power 6 cards.

So is he splitting each 6 pin to (2) 8 pins?

I have a question about powering GPU's, that's likely ridiculously simple.

I have 6 EVGA 1070 TI's and each has two 6 pin inputs going to it. If I'm powering these off an EVGA 1000 watt P2 power supply, do run two to 6 pins to every GPU? If I do that, then I don't have enough 6 pins for every card. I.E, I'd have two 6 pin connectors off each PS output to one card. Only allowing me to connect 3 cards. How do I get the 12 connections I need for the GPUs off the 6 connector PS?

Thanks!
