Hey all, I'm sure everyone is sick of these posts by now. I'm looking at getting an external GPU for my Early 2015 MacBook Pro 13" Retina. Because my MBP only has Thunderbolt 2, I was looking at a cheap Akitio Thunder 2 setup. I realised that it was going to be a lot of work to get the parts and mods necessary to power any decent GPU e.g. splicing, soldering etc... (none of which I feel confident doing) I did a bit more research and saw that the Thunder 3 was available. And now that Thunderbolt 3 to Thunderbolt 2 adapters now exist (Thank God), I can use the Thunder 3 with my MacBook Pro, supposedly with only an additional 5% decrease in performance from TB3. I'm wanting to install the EVGA 1050ti SC (the one without additional 6-pin power connection). Here is a link:  https://www.amazon.com/EVGA-GeForce-GAMING-Support-04G-P4-6253-KR/dp/B01MF7EQJZ

I also read that the stock Akitio supply could be replaced with a cheap barrel connection power supply of up to 120W, so that the PCI-e board can supply the 75W needed for the 1050ti to run. I got that information from this video: 

However, I'm still confused about the power situation. In another video I saw:   (around the 2 minute mark), this guy said that he used the stock Thunder 3 power supply to power the 1050ti (which only supplies 25W through PCI-e), and apparently worked fine with no issues whatsoever, What?! Or did I misinterpret it.....

I guess what I am trying to find out is, can I just buy the Thunder 3 and the 1050ti, plug it all in, download drivers (Bootcamp of course) and expect it to work with the stock PSU? Thanks in advance!

Hey!

 

I am in the same spot as you. Bough the Thunder3 enclosure and an 120W source. I will go for an 110W EVGA GTX 950 that will fit inside the enclosure. I would have gone for the new 1050 but they are not supported on MacOS. So if you plan on using it on MacOS I suggest you got for the 900 or 700 series or the RX460/470/480/Fury from AMD.

Also I would strongly suggest to chop your box, take the front off so you can fit normal size GPU. Better bang for your buck. Also improves airflow around your GPU. But that will come with custom made cables. No need for soldering. The barrel plug adapter comes with screw sockets and the PCI extenders and splitters are cheap to buy. If you want I will take a picture of my cables. Took me 5 minutes, a barrel plug (5,5x2,5mm), 2 PCI 6pin splitters (my GPU has 2 power sockets) and some insulation tape. 

Hope it helps.

Hi, 

All parts for you are:

You cant use the Akitio Thunder 3 power supply for gaming you will have problems. So you must buy 120W AC Power supply with Output: 120W, 12V, 10A | Plug dimensions: 5.5*2.5 mm

Hey,

Thank you both so much for your help!

I though the 9xx series wasn't supported my Mac. Or have they got drivers for it now? Yup I will definitely look at some Mac compatible cards, hopefully as low powered as the 1050ti, but maybe that's not possible...

As for the 120w power supply I'll see if I can find one that suits!

Thanks again Enjoy and Mehen!

Sooo...

I'm back again with another try.

Setup:

What I did:

Enabled tb3 via script, ran automate-egpu.sh (it saw the gpu, installed driver)

and...

The MacBook Pro sees the enclosure, the GPU, but no device (monitors attached...). If I hot unplug the enclosure, the MacBook Pro freezes as it should (black screen) so something is working right. If I plug the device via TB3 cable to the late 2016 MacBook Pro it works.

Advices?
