And a SWEX to make the case fan work.

A SWEX for the case fan? I don't get it… I directly attached the the fan to the PSU. And the PSU is working as soon as I switch it on because I use sth like the paperclip trick.

The power plug for the case ventilator doesn't fit in the PSU. But maybe I can find another solution for that.

Guess you need a molex to 3 pin fan adapter or SATA to 3 pin fan adapter.

Will update the main post after work. Try to avoid more confusion.

Problem was: I wasn't passioned enough to finish the post, because my GTX 970 wasn't a good card. Had 2 MSI cards and 2 EVGA cards so far (3rd card is on the way to me now, so I am without a card again). All of them had coil whine or coil buzzing issues. Even in my (old) main desktop PC rig.

Bottomline is: EVGA card and @Evo* guide are now working perefectly in Windows 8.1. Optimus. Most important it is working from a cold boot and a shut down/boot. Had trouble in OSX with the eGPU and not using it in OSX now (seems to be a mid 2014 MBPr problem?).

Yes that is probably correct :-)

I have the akitio thunder 2 and the gtx 970. It worked partly with my mac mini 2011 on os x 10.10.1. I used a powered pci riser and the power supply of the akitio (it wasn't working without the akitio psu). My psu for the gpu is a fortron 650 w.

I use this setup for video editing but not without problems. I kept geting kernel panic when rendering video causing my computer to reboot. And now it seems that the gpu has died. My computer rebooted and i smelled somthing burned in the eGPU. After that the gpu couldn't start.

What did i do wrong?

There might have been the problem of ground loops. Electricity trying to flow through the PCIe slot as there are two ground "sources" (the AKiTiO PSU and the ATX PSU).

Do not use the Akitio PSU together with a powered riser.

- - - Updated - - -

So, should I remove the akotio PSU? If I do so the akitio won't get any power.

Than there is something wrong because the powered riser should be enough to power both the Akitio and give +/- 75 Watt to the PCIe x16 slot.

This works great for my setup.

I just tested the GPU on my friend's PC and it works. What's with that paperclip trick, should I try that?

Well you need to do the paperclip trick to start the ATX PSU… without that the GPU doesn't get power, right?

The GPU does get power but the Akitio doesn't.

You could try to order another PCIe riser because that is not normal. Does you Akitio still works with it's own power supply when you don't connect the GPU?

I'll order a new PCIe riser and try that paperclip trick. About the paperclip trick, I just need to bridge the two pins shown on the picture whith a paperclip and that's it, right? What do you need the ATX PSU adapter for?

You need one of this three options to start your ATX (computer) PSU:

- paperclip trick

- PSU adapter (bridge), same purpose as the paperclip trick just inside a plug

- SWEX, same but with a switch to make it more comfortable

No idea… maybe sth broke when you smelled that burn smell. Have you installed the latest Nvidia Web drivers? Can you test in Windows?

Yes I have last drivers. Kernel panic happened before the burn smell. I tested the card on a PC and it works fine.

OK it's not working on Windows 8.1 even with external display. But it works for Mac OS X xD. It just boots up to a black screen on the internal display and no signal on the external display.
