Hey Uhlhorn,

I think the following line is what w4vz was trying to say:

sudo ./automate-eGPU.sh -url http://de.download.nvidia.com/Mac/Quadro_Certified/367.15.10.15f03/WebDriver-367.15.10.15f03.pkg

(This is assuming you are running Sierra 10.12.1 Build: 16B2659

It's the same one you have a few posts back (new_used_computer_parts)

Yours is definately different from mine (which is good news for you, I guess). Also comparing to the diagram in the opening post of this thread it seems correct to me. But I got only limited knowledge in this field, thats why I was opting for a ready made solution in the first place.

I'ts noticeable we both bought our adapters from the same eBay seller. Maybe he has gotten something wrong?

I had a nice email conversation with him and he is now sending me another adapter with different layout. Shipping to Germany might take a while though. Once I receive my unit I will gladly report whether it might be different again from you adapter.

Maybe one of the more experienced members can provide more feedback for you in the meanwhile

I just got my Dell DA-2 in, when I plug it into the wall with nothing attached the indicator light is orange, as soon as I plug in the the 8pin adapter (got it on ebay, looks like it's wired properly) the light goes out and nothing happens. Akitio box gives a green indicator light when using the psu it comes with.

 

Is the Dell DA-2 bad?

The LED on your DELL-DA-2 turning orange is normal behaviour.

Could you perhaps provide a picture of the adapter you purchased from eBay?

@Halbertus A 980 might only work if it is a reference card. If you still want to go the 980 way I can help you find the correct parts in Germany. Beeing able to fit a small 970 card into the AKiTiO and closing the case will result in importing a cable from the US which come with a big price.

Thanks for your feedback and for offering your support!

Unfortunately I was not able to find a GTX 970 that I had reliable information would work with my Dell UP2715K@5K@60Hz.

So I needed to go GTX 980. I found a great deal for an open box EVGA GTX 980 on Black Friday, so I ordered that. (for reference: https://www.amazon.de/gp/product/B00O3JZAYA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

Splitting a PSU line like that will just slightly reduce the efficiency of the PSU. It will not directly be a problem.

 

Be careful with overclocking a 980 on just a 220W PSU. That card can draw well over 220W if the power limit is high enough.

Thanks for the Info. I will not overclock the graphics card. It is only being used for video production, memory bandwidth is important in that case and I guess the GTX 980 220GB/s should be sufficient for quite some time.

In the meanwhile I got my custom cable (shipping from North Carolina, USA) and the Dell DA-2 power supply.

Unfortunately the colours of the wiring (black/yellow) / the placement of the paperclip seems to differ from the diagrams that can be found in the beginning of this thread.

There is few different ways on how I could connect the adapter cable to the PSU. None of both variants is identical to the image in post #1

Would this still work? Am I missing something? Or is the adapter soldered incorrectly?

UPDATE: I contacted the eBay seller, he told me I got a wrong cable indeed.

Variant 1:

Variant 2:

So, after reading about your builds on this forum a few weeks I finally decided to build an eGPU for myself to improve performance in video editing software.

I got an Akitio Thunder 2 and a DELL DA-2 Power supply that i would use to drive an nVidia GTX 970.

As i am not  really into physics and tools I ordered a cable solution from eBay:

Unfortunately I cannot find a GTX 970 that is capable of connecting my Dual Cable Monitor, which requires 2x miniDisplayPort (Dell UP 2715K)

So I had to change my mind and would now like to use a GTX 980.

This card however requires 2 X 6-Pin Connections for power.

As shipping costs to Germany for the above cable solution have been quite expensive I was wondering whether I could still use that cable and add something like a 1x6-Pin to 2x6-Pin Adapter like one can be found on Amazon:

While not that aesthetically pleasing this could be an affordable solution.

Do you think this would work? Or would this cause any (risk of) damage?

Thanks!
