Hi all,

Sorry for the delay. too much work here.

All started when I saw this article on Pro Tools expert: http://www.pro-tools-expert.com/home...-in-my-mac-pro

From there I've contacted the guys from "Create Pro" and they sent me that exactly splitter cable you see on the article. Guess what? Didn't work! Although the mac pro end of it was right, the other end of the splitter didn't fit the AVID HDX cable (but fitted the video card). So my tech used the second HDX cable provided with my system (the one for PC), and used it to adapt to the one supplied by Create Pro. And it worked!!! So its not easy, but its possible.

I do think that you can find the right splitter on eBay...

As I said before I personally recommend using the splitter cable to power both the HDX & GPU, then the second Mac Pro port for the GPU. That's the way I'm using it.

Oh, and my video card is GTX 970.

Hope that helps!

Cheers.

Ps. All that is working on an upgraded Mac Pro 4.1 (now 5.1). From 8 core 2.26 to a 12 core 3.33.
