Yes that is good. You will have to cut off the 6-Pin. After that you will have 2x Molex plugs with wires (black and yellow). yellow has to go into the + side of the barrel plug with the screw terminals and black into the - side.
The barrel side will than go into the AKiTiOs back side, the exact same spot where the original PSU would go in.
The Molex plugs have to be plugged into the matching inverse molex plugs of the PSU.
Ah, understand now, I thought that cable was coming with the PSU.
Final (Final) List:
- AkiTiO
- Galax GPU
- PCIe 6 Pin - 2 Molex (Cut off both Molex heads, both yellow go in inverse positive, both blacks go in inverse negative)
- 90 Degree Cable (Top of GPU, then wrap the remaining around the bottom of the case then connects to PSU outside of the back of AkiTiO case)
- Starter Bridge Adaptor (PSU Paper Clip replacement)
- PSU
Man, I don't know how I can thank you Dschijn. I'll give you guys an update on how it goes after I order all the parts and set it up.

Yes list is good, but you still need the molex -> 6-Pin PCIe (I think I am repeating myself… ). You don't want to cut the cable of the PSU, you want to use an ADAPTER in between.
Ah, my mistake, I kept thinking that was the Molex to Barrel Adapter.
Would this cable work? http://www.amazon.com/HDE-PCI-Express-Pin-Molex/dp/B002CZANA8
Where would this fit at now, or was it in the overview that I posted with the ASUS card?

Yes it would be like the white cord.
Take a look at the image you posted. You can see that the ASUS card is as high as the case of the AKiTiO is. Now imagine plugging a plug into the card (where the green arrow points to). You will not be able to close the case because the white cable is perpendicular coming out of the card pointing upwards. There are two ways to solve this problem:
1. get a slimmer card (ASUS cards are very wide) and the edge of the card will be lower as the case
2. get a 90° PCIe cable to route the cable parallel to the card itself and not stick it out on the top
Yup, starting to understand now. Was i correct in stating where the 90 degree would go, and how the other part would flow under the card and be connected to the PSU Molex by removing the grill on the back of the case? Also, can you verify that the cable needed comes with the PSU i posted (Not the 90 degree cable, the 6-Pin, believe it is).
Final checklist:
- AkiTiO- Galax GPU
- Molex to Barrel Adapter
- 90 degree cable
- Starter Bridge Adaptor (For Pin trick)
- PSU (Linked above)
Thanks, finally feel comfortable.

I had it open in a tab, hope that helps.
Edit: I copied/pasted it in a reply, but it was removed.

You forgot the barrel plug
Yes, the barrel plug with the red cable is what is pwoering the AKiTiO and the PCIe slot. Yours would come from the PSU and two of its molex plugs to your selfmade molex -> barrel adapter.
The 90° 6-Pin plugs are necessary to beeing able to close the case! Thinking about that, you might need to extend the wires, since they would too short to bring out of the case.
Please keep in mind that I used an external Dell DA-2 PSU and my wiring is a bit different.
Maybe reading my basic guide would help you to understand most basics (but the thread is currently offline).
I don't understand how the 90 degree 6-Pin fits into this equation. Where would I plug it in at on the GPU, and where would I put the other end at? I guess the 90 degree angle part connects the GPU at the top, where shown at in diagram, and then loops around bottom of the case to connect to the PSU Molex cable (After removing back grill of to case fit cable). Also, does this PSU (linked above as New PSU, some reason when I paste link it shows a newer but it's not correct one) come with the 6-Pin PCIe Express to Dual 6-Pin and/or a 8-Pin PCIe Express 2.0 Cable (Or is it just called the PCIe cable). Thanks.

You have to use an alternative PSU and should never use the AKiTiO PSU.
The eGPU setup has 2 power inputs:
- the GPU itself (side of the card with 6/8-Pin PCIe plugs)
- the AKiTiO
Powering the AKiTiO can be done by a powered riser (here you don't use the barrel plug) or a barrel plug (to be plugged into the back of the AKiTiO case), like you linked. Both ways have to recieve the power from the same PSU that is powering the GPU directly, so only use one PSU!
The barrel plug you linked is good and you would only need a 2xmolex -> 6-pin PCIe y-cable, cut of the 6-pin and use the Molex plugs to connect to your PSU and the wires to plug into the barrel plug.
I have no problems at all with my mini setup, it is even running overclocked and boosts over 1400MHz stable. The only thing is that it is hitting 80°C when running demanding games and is overclocked.
Please keep in mind that you will have to use 90° low profile 6-Pin PCIe extensions if you want to close the AKiTiO with such a short card (available on eBay).
The PSU looks fine.
If you don't want to do the paper clip trick, you can get this one: http://www.amazon.com/24-Pin-STARTER-BRIDGE-WITHOUT-MOTHERBOARD/dp/B00K38IKRY
Here's the new list:
- AkiTiO
- Galax GPU
- The starter bridge: http://www.amazon.com/24-Pin-STARTER-BRIDGE-WITHOUT-MOTHERBOARD/dp/B00K38IKRY
- The molex -> barrel plug: http://www.amazon.com/Link-Depot-Express-Adapter-Inches/dp/B000JWTIKC/ref=sr_1_6?s=pc&ie=UTF8&qid=1453127843&sr=1-6&keywords=6-pin+pcie+molex
- 90 degree low profile 6-pin PCIe extension: http://www.ebay.com/itm/NEW-6-Pin-to-6-Pin-PCI-E-90-Degree-right-extension-w-low-profile4-USA-MADE-/261225911899?hash=item3cd247165b:m:mxGogGSSsz95lLh97DTDU0A
Unless I'm not understanding the 90 degree extension correctly, how would I power the GPU with the case , closed? As in, how would my molex cable from the PSU connect to the extension inside the case? I looked at your recent setup, and would it be that red cable you have coming out the back of your case, but that looks like it's plugged into the barrel hole on the AkiTiO?
Man, i feel like such a noob, thanks for everything again.

You can use Riser cables in two ways.
1. powered and without soldering
2. not powered riser and solder a barrel plug
The 2nd option might give you better results if the 1st one fails.
Nevertheless... I used an EVGA GTX970 FTW+ in my 2nd build with a powered riser and it worked very well. It might just be the root of problems if your eGPU keeps crashing your system.
I really like EVGA as well, and the awesome customer service helped me a lot with my GTX970 cards, but in the end all of them had the coil whine/buzzing problem (like all the other 970 [I had 5 cards in total with MSI, EVGA and Galax]).
PSU: Just get any PSU (not older than 3-4 years if you get sth 2nd hand) and with the correct amount of 6/8-Pin PCIe plugs. Most 500+W PSUs should be good for that.
Has your Galax card ever given you an issue? I really like the idea of the small card in the case, and actually having a case. What do you think of this Molex to Barrel adapter? (http://m.ebay.com/sch/i.html?isRefine=true&_odkw=5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power&_from=R40%7CR40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power+-female.TRS0&_nkw=5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power+-female&_sacat=0&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X5.5X2.5mm%20DC%20Power%20plug%20Terminals%20Connector%20Adapter%20Power%20-female.TRS0&_mwBanner=1)
Would I just separate the wires from one of the molex plugs with a PSU and arrange the yellow in positive with the black in negative in the adapter, then plug it into the AkiTiO Case?
How would I power the GPU then, if the caseis closed, since wouldn't I need Molex cables directly to the GPU to give it the remaining power it needs, since the AkiTiO can't supply enough, or would the PSU Molex -> Barrel fix that when plugging into the back of the case?
- Galax GTX 970 (http://galaxstore.net/GALAX-NVIDIA-GeForce-GTX-970-OC-4GB_p_32.html)
- AkiTiO Thunder 2
- Molex -> Barrel Plug adapter (If verified will work)
- How about this PSU: http://www.amazon.com/EVGA-Continuous-Warranty-Supply-100-W1-0500-KR/dp/B00H33SFJU/ref=pd_bxgy_147_3?ie=UTF8&refRID=0C67G8XZN7T7B221JN0E
- Can't think of anything else.
Thanks man, grateful for the time your taking to help me out with this. Sorry for so many questions.

There is no soldering between the PCIe board and the GPU. All the soldering I did was for the power between my Dell DA-2 220W PSU and the AKiTiO (barrel plug mod) and the GPU (2x 6-Pin PCIe).
Dschijn, thanks for all the help thus far. Since I prefer EVGA cards, I'm most likely going along with an EVGA GTX 970 over the Galax. I'm going to take the chance with a powered riser, and see if that works out. If it fails, I plan to mod the AkiTio case so that the EVGA can fit.
Heres what I'll get:
- AkiTiO Thunder2
- Powered 16x Riser with Molex.
- PSU
*What PSU would you recommend?
I'm not entirely comfortable with soldering, since I don't want to mess anything up.
Really appreciate your quick replies and help. Thanks.
Edit:
In this few minutes I've already become unsure of which way to go. I found a thread with how to make a mild to barrel plug, and there are adapters that I can buy (which I'm assuming would be just what I need), and if that adapter just goes PSU molex to the adapter, then adapter (barrel plug) to Akitio, with a card sitting on the PCIe, then that sounds simple and not hard at all. Would these types of adapters work?

The longer cards have in general a better cooler and better power delivery for the GPU. That is more important to high overclocks, so I really don't see any reason why you shoudn't get the smaller card.
This is my latest build: https://www.techinferno.com/index.php?/forums/topic/7667-2014-15-mbp-iris-gtx97016gbps-tb2-akitio-thunder2-win81osx1010-dschijn2/
Really nice modding. After setting your gpu on the PCIe board, did you solder anything between the two? Or is the soldering just done when you made the PSU to barrel plug modification.
Again, thanks.

@Lockbox30 You can use any card... The benefit of short cards is, that you don't have to run them with a riser or bend the case of the AKiTiO. Long cards can be used without a riser, if you are willingly to bend the front part of the case.
I am running my small Galax card inside the AKiTiO with a closed case since a year and have no problems at all. Of course it depends where and how you position the cables inside, so they aren't at risk in the first place.
There are two kinds of riser cables: powered and not powered.
The powered ones are often not very good quality and can cause problems.
The not powered ones will require a barrel mod to power the AKiTiO from the back and not trough the riser (like powered riser does).
@iddinmx Yeah the card seems fine. Maybe you can take a look at the single fan EVGA cards as well?
Your list is good, but you will still have to make a Molex -> barrel mod to power the AKiTiO with the Corsair PSU.
Are there any differences between the Galax and EVGA cards besides just length? Of course I'll guess cooling, but modding the case could fix that. Do you have a post I can check out to see your build and how you setup everything? Also, if I go the small card route, I'll have to modify the Molex to the barrel and that'll be my only power source. PSU modified to barrel plugged in to Akitio.
Thanks, really appreciate it.

@Lockbox30 We don't recommend using that powered riser cables since they can cause stability problems and are often of poor quality.
The alternative way would be to get a quality riser cable and power the PCIe slot and AKiTiO with a modded barrel plug.
Is there a reason why you want to use it with a riser?
Answers:
- no
- no
- yes, you will have to do the paper clip trick
- can
- connect to the I/O of the eGPU, not the Mac or any TB port.
I would have gotten a riser cable since the EVGA GTX 970 wouldn't fit in the case. I hadn't realized this post got submitted since I'm in pre-registered mode. Would you recommend getting a smaller card to fit in the case?
*Edit
Something like this where he uses the riser, and mentions that using a small card can sometimes cause a burning on the cables inside the AkiTiO case.

If i plan on getting the AkiTiO Thunder2 Box, and a GTX 970, would it be smart to get a smaller version such as the Galax, or a bigger one such as a EVGA. Are there any differences between the two cards, having one smaller/bigger? Also, if I go with the Galax, and since it'll fit in the Thunder2, would I need to solder anything to make the Galax fit in the Thunder2 while being operational? Lastly, if I get the EVGA, I know I'll need a riser, would I need to solder anything if I go along with using the Riser to connect the PCIe card to the GPU, and having the PSU power the GPU with the Riser transporting power to the PCIe, and leaving the AkiTiO's PSU unplugged and not in use? Any recommendations on a PSU by any chance?
Thanks guys, appreciate it.

How's it going.
Recently, I've been looking into eGPUs for my rMBP 13". (Early 2015, 13", 2.7 i5, 8gb, Intel Iris Graphics 6100 1.5Gb)
I started looking at the Bizon Box 2, but found the threat where it's overpriced and the AKiTiO Thunder2 PCIe Box is better.
I'm looking into getting an EVGA GTX 970 SC ACX 2.0.
I've been looking at videos and setups on using the AKiTiO Box, but I still have some remaining questions.
Sorry if they've been answered somewhere already.
Here's what I plan on getting:
- AKiTiO Thunder 2 PCIe Box (About $220)
- EVGA GTX 970 SC ACX 2.0 (About $350)
- PCIE 16x to 16x Cable (Link: http://www.amazon.com/PCIE-Powered-Flexible-Extender-Bitcoin/dp/B00GUKRX6S/ref=pd_bxgy_147_2?ie=UTF8&refRID=0XV9YYBVV8T225GQT3JR) (About $7)
* Can someone verify that this will work. Thanks.
- PSU (Not sure which to get, new to this.)
- Not sure if there's anything else I will need. (Guessing that the cables needed will come with GPU/PSU)
Here's a blog that I found when looking, I'd like something similar, as you can tell from my parts.
Link: https://odd-one-out.serek.eu/thunderbolt-2-egpu-setup-using-akitio-thunder2/
Now my questions are:
- From the blog-post, and going by his setup, will I have to solder anything? (I'm guessing not since people usually solder their eGPUs when making them fit in cases)
- Would I need to make any adapters to get the PSU to work with the Graphics Card?
- Paper Clip trick - I'm just going to search it.
- Should i disable the fan inside the AKiTiO Case or just leave it on?
- If I get a monitor s to use, can I connect to the GPU by the HDMI port on it, or would I connect using thunderbolt to my MBP, then HDMI to the Monitor?
I appreciate all the help, and sorry if anything was already posted and answered.

Apologies, I meant to say cut off the 6-Pin end, not the two Molex heads.
"You will have to cut off the 6-Pin. After that you will have 2x Molex plugs with wires (black and yellow)."
