Who knew 6,1 could still be in 99th percentile?

Wow - superb results Wink Offering eGPU's would make much wider range of customers for flashed cards.

So basically your EFI makes these cards run under Windows even with zero OS mods.

What happens if a customer puts such card in cMP - will it work or is it some kind some of special rom which will work only as eGPU?

The MP's two mini-PCIe connectors top out at 120w total?? That's not even close to the spec of 75w per 6-pin connector. If that's the case, Apple seriously fucked up using shitty traces to provide the power through the mobo.

120 watts is highest peak I've seen that hasn't lead to shut down on a single cord

I've never seen both in this area at same time as most cards draw more from one side than the other

It makes sense about the lopsided power draw actually, since with a 2x 6-pin to 1x 8-pin adapter the cards have no way to differentiate between the two cables and thus no way to load balance the power draw. That also means that even with the SATA cable option there isn't a safe option for this in a Mac Pro outside of external PSU because you run into the same problem using 2x SATA -> 8-pin connector and a single PCIe 6 pin connector from the motherboard. Either way, you're in for potential current overdraw. On the plus side of things, the SATA cables, flimsy as those generally are, are likely way better than the pathetic motherboard traces used for the mini-PCIe connectors.

Heh, that's the spirit Grin
I have also an external power for the optical drive slot laying somewhere, it will be useful again Wink
Thanks!

With the new crop of affordable chassis, eGPU makes more sense then ever.

Same level of functionality used to be $1,000

So to sum it up, the cmp mobo is too old and shitty to power the 1080ti or titan Xp?  Angry

Well, that's the "glass half empty" version.

Or you can say "Gosh, who needs 6 SATA drives, I'll grab power from one of those and put a 2017 GPU in my Chesesegrater" and be the "Glass half full with a silver lining" type guy/gal.

All the talk is about the PS.  What about the MB traces when they card draws all that current?  The main reason I went for the GTX 1080, was the one 8 pin connector and the lower TDP than my previous GTX 780.
