Well… kind of. You need to keep in mind that you might need 6 or 8-pin connectors for the GPU. If you just want to power a GTX 750Ti by a powered riser any SFX will be fine.

To get an idea about the possible PSUs, here is a list from a german search page: Netzteile mit Hersteller: be quiet!/Chieftec/SilverStone, Formfaktor: SFX Preisvergleich | Geizhals Deutschland

I am using the Chieftec SFX-500GD-C because it has a quiet 120mm fan and two 6/8-Pin PCIe connectors.

Thank you on answer. I will see what can get of this from link in Croatia

Is it 300w sfx enough?

Yes there is a Dell DA-2: http://forum.techinferno.com/diy-e-gpu-projects/8304-gtx970-dell-da-2-test-results.html

But keep in mind that you might need to rearrange the wires.

Thank you for advice

I will buy a ATX PSU,that is best solution. i wanna safe some space on my desk with ac adapter. but easiest way is buy atx i think,and have no problem with wires

Hi, @VladoKc. Here are the parts I used.

I also purchased a GTX760, which I now run instead of the 750Ti most of the time (more stable than the 750Ti, and can be run without a powered riser since it can accept an 8-pin plug from the ATX PSU):

Good luck! Let me know how it turns out.

Thank you for the post,you help me a lot

I am look for gtx 750 ti because price,the gtx 760 is little too more for my budget right now :/. Is there some other good graphic card in price range gtx 750,of course with stabile performance? i plan spend about 200$ for graphic card.

I am from Europe,here is AKiTiO more expensive than in US

what kind of adaper is capable to provide enough power? i read some dell adapter come with 220w

or i must buy atx psu?

HDD Power Supply AC 12V 5V 2A for Hard Drive Molex EU | eBay

is this capable to supply enough power for gtx 750 ti over riser?

Thanks, @goalque, I wasn't aware of the different types of risers. That explains it! I appreciate the electrical help, I'm not very experienced with that.

Update: I received my MSI mini-ITX GTX 760 today and am running it now on the AKiTiO box with my 500w ATX PSU providing power through the PCIe 8-pin connector on the 760 as we speak. It appears to be completely stable in OSX Yosemite (so far). It runs an external display perfectly both on my 11'' Early 2014 Macbook Air and on my 13'' Mid 2014 Macbook Pro (Retina). Interestingly, benchmarks on each are pretty close to being the same (see below). It appears that there is little-to-no performance difference between a Thunderbolt 2 connection (on the Macbook Pro) and a Thunderbolt 1 connection (on the Macbook Air) when using an eGPU with the AKiTiO. My speculation is that this is because the 4 PCIe lanes the AKiTiO provides already max out at 5Gbps themselves, well within the throughput range of both TB1 and TB2.

In summary:

1) Early 2014 11'' Macbook Air (TB1) with GTX750Ti running purely on the AKiTiO's own power (no riser): works under both OSX and Windows, but unstable under load, scores roughly 440 in Unigine Heaven benchmark "Extreme" @ 1080p.

2) Mid 2014 13'' Macbook Pro (TB2) with GTX750Ti running purely on the AKiTiO's own power (no riser): works under both OSX and Windows, but unstable under load, scores roughly 440 in Unigine Heaven benchmark "Extreme" @ 1080p.

3) Early 2014 11'' Macbook Air (TB1) with GTX750Ti running on the AKiTiO with a 500W ATX PSU via a powered riser: works under both OSX and Windows, stable under load, scores roughly 440 in Unigine Heaven benchmark "Extreme" @ 1080p.

4) Mid 2014 13'' Macbook Pro (TB2) with GTX750Ti running on the AKiTiO with a 500W ATX PSU via a powered riser: works under both OSX and Windows, stable under load, scores roughly 440 in Unigine Heaven benchmark "Extreme" @ 1080p.

5) Early 2014 11'' Macbook Air (TB1) with Mini-ITX GTX760 running on the AKiTiO with a 500W ATX PSU via 8-pin PCIe connectors (no riser): works under both OSX and Windows, stable under load, scores roughly 660 in Unigine Heaven benchmark "Extreme" @ 1080p.

6) Mid 2014 13'' Macbook Pro (TB2) with Mini-ITX GTX760 running on the AKiTiO with a 500W ATX PSU via 8-pin PCIe connectors (no riser): works under both OSX and Windows, stable under load, scores roughly 680 in Unigine Heaven benchmark "Extreme" @ 1080p.

Update: The Mini-ITX MSI/Nvidia GTX760 appears to run properly as an eGPU even when using the stock Mac OS X graphics driver in Yosemite! I'm not entirely sure why this is - perhaps because Yosemite supports the GTX760 natively? I'm surprised it will allow it to run in an eGPU though. Can anyone else with a GTX760 and an AKiTiO confirm this?

i read your post and i plan to buy gtx 750 ti (60w) and akitio thunder2 for my mac mini 2012. i just need help. what kind of power riser do i need a buy to work stable? can this work with any kind of power supply? for example 400w?

Welcome. Yes, there is one GTX750Ti implementation running purely off the 60W AKiTiO Thunder2 AC adapter without any riser. See http://forum.techinferno.com/implementation-guides/8569-%5Bguide%5D-2011-11-macbook-air-gtx750ti%4010gbps-tb1-akitio-thunder2-osx10-10-a.html#post116853

Recommend you also review specific implementations for your machine at http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#Thunderbolt

thank you for quick answer. that is good if work without any riser.

Helo. I am new at forum. First i want tell hello to everybody

I read a lot about akitio thunder2 pcie box,i must tell its great product for what i have read.

Now i have a qustion. I plan to buy gtx 750 ti for my mac mini 2012. That graphic card need only 60w power. Now i am corious will it work with akitio thunder 2?

do i need more power or is that all i need. thank you everybody for such great forum. sorry for my bad english,i am from Croatia
