The thing is: a single molex plug is way too overloaded to provide all the power. You should use at least 2x molex plugs. Better to use the 4/8-Pin for the mainboard and use as many 12v/ground lines as possible.
-
Try different times when to tunr on the eGPU:
- boot selection menun
- during the boot
- in windows...
-
try and power on the eGPU when in the boot selection menu.
-
Yes. What was the problem? x4 is normal, because TB2 is limiting it. Cuda driver, yes install!

Sure you can. yellow = 12V and black = ground.
Check all the cables, especially the TB cable. can you try connecting the eGPU to the Mac after half of the boot.

@Yavor You made a barrel plug to power the AKiTiO with the corsair 650? Any overclock applied? If overclocked, lower the overclock!
-
So, you are using this 8-Pin to conenct to the barrel plug? That is good! but still no idea what your problem could be. Can you test the GPU in a PC?
-
And you have an adapter from molex to the barrel plug?
-
Have you connected the two 6-Pin adapters? Does the PSU even have that many?
-
@shirazigs That depends on the case... unfortunately the 90° riser must be pointing into the other direction. The risers you linked would point (in a normal PC) down and away from the mainboard. We need them point towards the mainboard.
The risers you linked are not "wrong", but if you want to use them you will need a long riser cable to get all the way around the card and back to the AKiTiO.
-
Now you just need a good case
-
In OSX it will work (with an external display!).
-
@Arckititta So you mainly want to use it in OSX, right?
The PSU is very weak and might not be enoguh for that GPU. A 680 can use a lot of power on the 12V rail.
"csrutil disable" ... did you even bother to google it?
You just need to reboot into recovery mode of OSX and open the terminal there and disable csrutil. After that, reboot normally, install script, reboot into recovery,enable csrutil, reboot into OSX.
-
@shirazigs Have you done a reboot? Any manual changes in OSX before you ran the script?
@AlexMacPro 1. Wrong section 2. there is currently no way to make a eGPU work in Windows with a nMP

Had the same with my setup. Especially after using it in Optimus and with an display I had to do multiple reboots.

Had a 980Ti working great in Windows...

@shirazigs How are you powering your AKiTiO / PCB?
- 1
-
It could work, but even with a 750Ti and a 120W PSU some people had stability issues, which I think a caused by the "weak" 120W PSU.
Using a bigger GPU might result in that situation for you as well. Maybe consider stepping up to sth more powerful. (Dell DA-2 220W?)
The ITX cards from ASUS are often very wide. ASUS cards with 6/8-Pin PCIe power plugs will not fit into the AKiTiO closed. Maybe they do fit without the PCIe power plugs.
EVGA should be the safest way: evga-geforce-gtx-950-low-power
-
OSX? Windows?
A1: For OSX there is a script to disable the internal screen!
A2: Don't put your eGPU system into sleep. That is not working well for a lot of people. Don't even let your Mac put itself to sleep.
-
Are you still useing the AKiTiO PSU? If yes, DO NOT USE IT!
The riser you have is a x1 or x4? Why not get a x16? Riser are in general the weakest part in a eGPU system. Can you test without the riser and make a barrel mod to power the AKiTiO with the 600W PSU?

The nMP is not working as easiliy with an eGPU as other Macs. In OSX it is no problem, but Windows + eGPU + nMP has only been "teased" by MVC (Rominator) und netkas in their own forum. They are currently not willing to share a guide.
-
@Rttr84 In OSX that is no problem. Please keep in mind that you should use an external monitor if you want to game with the eGPU and that the internal display might be laggy and not of use when using with an eGPU+external Monitor.

60FPS in The Division with a GTX960? o_O
I think that game is a good example on how bandwidth can affect the performance. This will vary with most games, some run good some not. You can see that in the link Morv posted.

Try and lower the power limit clock speed in Windows with EVGA Precision X or MSI Afterburner.
Maybe even the 120W PSU is at its limit with the 750Ti. The card doesn't have any 6-Pin PCIe power plugs on it, right?!
