How could that be ok if the GPU uses more than the PSU can provide?!
No no, not just PSU. 300W from PSU+The 75W provided from the adapter connected to the box.
So this:
Plus our GPU.

Have always done. Done via the AKiTiO DC jack barrel port.
Only time this has been avoided is by when a PCIe riser extension with 12V input was plugged into the AKiTiO PCIe slot. This is NOT recommended as it leads to Gen2 signal degradation that has resulted in an unstable implementation.
I see. But other than PCIe power adapters(8pins and/or 6pins), Akitio can only provide 75W right? So if we have a 300W PSU, and our GPU consumes 325~330W peak, it should be enough?

Do we still have to feed Akitio Thunder2 if we are certain we're powering our GPU with a right amount of power? I figured we do, but just asking to make sure.

Interesting! Does this also enable using the internal display with an eGPU after disabling the 650m/750m? in the system manager?
I'm not certain how to check the setting you said. If you can be a little more specific, I'll definitely check! But let me explain the display situation in another way:
So if I close GT750m, Iris Pro works on its own. If I open GT750m, I can use it with Nvidia Optimus driver. Theoretically if we plug an external GPU using Thunderbolt, we must be able to use it with Iris Pro+Nvidia Optimus usig internel monitor... Unfortunately I can't test this, because currently I don't have the hardware needed.

Hi everyone, I just bought my new 2014 rMBP during Black Friday and now have many problems with eGPU setting.
I've already set the eGPU for my macbook air 2014 and it works pretty perfect.
Here's my specs:
i7 2.5GHz
512g SSD
Iris pro +gt 750m
GTX970 msi gaming 4g
I first upgraded my Mac OS to 10.11 so that I think I might use the new bootcamp assistant (without flash disk) to install windows;however, it still asks me to use a flash disk for installation. So I had to follow the instruction to use USB disk to install Windows 10, ending with "failure configuring windows updates" and then I go back to mac to remove the windows partition and install windows 8.1 instead. However, the installation still failed, and what's more when I boot into Mac OS there's a banner and that might mean my Mac OS is also broken. So I restore the whole computer and manually use EFI to install windows 8.1 without. But after installing bootcamp drivers, I can only use dGPU in windows (which is also reported by many other users). In order to enable iris, I installed rEFInd and load Apple_OS_set. And I installed Nvdia drivers for GTX970, but every time I plug the thunderbolt to MBP in rEFInd interface or that option select system interface, it just freezes and I can't get into any OS(But in the option one, I can't still use mouse to choose wireless); if I plugin the thunderbolt (and power up gtx 970)before I power up the macbook, it doesn't show up anything and can't hear the booting sound. I succeeded in booting into windows twice, the first time is that I get into windows with a BSOD and automatically restart; and it magically go into windows with perfect gaming performance( I test GTA V); another time is that I pluged the thunderbolt during the rEFInd interface and it didn't freeze so I also get into the system with perfect gaming performance. So I suppose the driver works good and the only issue is that I have to figure out a stable procedure to power up.
My Question is:
1.Why can't I install windows thru bootcamp without flash disk? And why can't I install windows even with flash disk?
2.Is there anyway to make iris pro available in windows?
3.What should I do to make the eGPU works?
4. Is there any different to use EFI and bootcamp to install windows ? Is that possible to install iris driver before I install bootcamp driver so that I can enable iris?
I am considering using apple_set_OS and disable gt750m in windows just like the implementation guide of that 2015 rMBP with R9. But I am afraid that if I disable gt750m and it still couldn't recognize iris pro, I have to reinstall the whole system.

The GT 750M Macbook variants disable the Iris Pro upon booting Windows and therefore the Iris Pro is not visible and no driver is installable. People with GT 750M Macbooks aren't having issues with internal display use together with their eGPU for no reason. If it was that easy they'd be doing this.
I just found an actual solution.

It works, here is a screenshot from my device http://i.hizliresim.com/yoaA80.png The thing is, you have to flash the EFI everytime you boot via rEFInd. And I'm having some issues with resolution, but I guess it's manageable with Intel app.

Hi guys, I have an eGPU project, but I'm limited on budget.
Here is my -planned- rig:
2013 rMBP w/ GT750M(ME294)
Akitio Thunder2
Corsair CX430
EVGA GTX 970 *insert any model here*
So the question is, will I be able to run this rig with the internal display, and I really don't want to buy a monitor. Some peeps wrote about Nvidia Optimus, but I don't know what it is. So If you can explain, or drop a link about optimus-internal monitor relation, that would be great.
Addition: I will run the system on Windows 10, or downgrade to 8.1 depending on your answer.
Thanks and enjoy your systems:Banane04:

1. You need another disk because you have to boot the computer via USB. Either connect another disk or a USB drive. The reason you need bootcamp is that it will install drivers into windows files. So after setup you don't have to install any drivers.
2. Read fourth reply.
3. --
4. refer to second answer.

@TYRTlive: That are just the official specs. We think that they have to write that, because of restrictions from Intel regarding eGPUs. Additionally the PSU way to weak to run anything faster than a GTX 750Ti and it's just noct official supported / guaranteed to work.
Bootcamp incompability is because Apple isn't supporting all TB features in Windows, like sleep/standby.
But there are multiple people that made it work and even AKiTiO is having an eye on the eGPU community.
Thank you, so it works fluently.

On Akitio Thunder2 site, it says the product is not compatible with bootcamp, and cannot used with GPUs. Did you had any problems with bootcamp or using your gpu?
-
Yes. TB2 can offer PCIe 2.0 x4 performance on a AKiTiO or any other direct PCIe->TB2 case. PE4C will be limited to sth like PCIe 2.0 x1. More and more games require high bandwidth!
You can get an idea in this report: GeForce GTX 980 PCI-Express Scaling | techPowerUp
Thank you. I'm multiTYRT from youtube
I had some questions but I read your guide, it's so useful. Thank you again for a guide like that.Yes. Can see more detail on how the native 10Gbps-TB1/16Gbps-TB2 beats 4Gbps-EC2 in these threads:Thanks again, it looks like there is a huge difference between mPCI-e and TB.

Avoid 4Gbps expresscard solutions (PE4C/EXP GDC + Sonnet EE) on your notebook that has a 10Gbps-TB1 or 16Gbps-TB2 port. Instead use a native Thunderbolt enclosure for better performance, less complexity and lower price. See http://forum.techinferno.com/enclosures-adapters/7205-us%24189-akitio-thunder2-pcie-box-16gbps-tb2.html . Carefully read the links near the bottom of that post on how to get 75W slot power and how to extend the chassis for cards longer than the 8" that do not fit into the factory-delivered chassis.
Lots of examples of the AKiTiO Thunder2 in action at http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#Thunderbolt
First, thank you for your reply. So you're saying that using a direct Thunderbolt feeder(I mean AKiTiO Thunder2) is way more logical, way more powerful. Am I right?

Hi guys, I'm going to buy EXP GDC Beast or PE4C, which one i should buy i'm not decided yet. But I have a more important question than choosing. I see both of set-ups using HDMI to any PCI port. I'm using a MBP(i7 4850HQ, GT750m) so I have to use thunderbolt. I think that can I use a direct HDMI-to-Thunderbolt converter instead of ExpressCard-to-Thunderbolt converter? Because If I have to use ExpressCard-to-Thunderbolt, I have to convert it with a Sonnet Echo ExpressCard Pro(which is an expensive way to use thunderbolt.) I think there is no difference two ways to use Thunderbolt. I really need help about this, because Sonnet Echo ExpressCard Pro is too pricey($170)

Thanks! Now I get it.
