Best option for Akitio Thunder2 PCIe Box w/o modding

Hey guys, how are you?

I *think* I´ve done my homework. Been using thunderbolt chassis for my audio interfaces but I happen to have this Akitio Thunder2 PCIe Box laying around that I wanna put to use...

I´ll be downgrading to High Sierra (15" mbp mid 2014)... I wanna know what´s the best (more powerful?) GPU that I could use with the Thunder2. No mods beyond upgrading the power brick (I want to keep the case closed too, so no large format gpus). I need simple and classy. Smile

Any suggestions?

Thanks so much!

DC.

@destinyschild, assuming you want the eGPU to work in macOS, you need to stick to AMD. I use the one model of RX580 that fits inside: a single fan MSI RX 580 V1. You will still need to use a pair of pliers to bend up (about 90º) the top front lip on the inner enclosure to fit the card in. I leave it like that and run with the cover off. It looks like there are models of RX 5500 XT that would also fit. I don't think there are any better cards by AMD in such a small form factor.

If you're using it only in Windows, then consider Nvidia: there are a number of mini ITX size GTX 1060/1070 and RTX 2060 models that would fit and are faster.

To fit with no modifications, the card needs to be < ~193 mm long (EDIT: with internal fan removed). ~200 mm will fit by bending the top lip. Of course, if you cut/bend open the whole front of the enclosure, you can fit a card of any length (search the site for some examples).

With the DA-2, I recommend a card of 150W TDP or less. Cards that need more power will need to be underclocked. Note that the TDP of any individual model may differ from the reference specs listed by AMD or Nvidia. Check the vbios listing in the techpowerup database to be sure. If instead you use a regular ATX psu, you won't be constrained by power.

Thanks so much, man!

High Sierra supported Nvidia cards so the best option for you would be a 1050ti which doesnt require any more than 75w.

This is the thread you need... https://egpu.io/forums/thunderbolt-enclosures/akitio-thunder2-and-thunder3-gpu-size-to-close-the-akitio/

Thank you! Can´t wait to get gaming! Grin

@destinyschild, let us know how it goes! Just to be warned - Nvidia cards dont perform that well in macOS, if you are gaming solely in macOS i'd maybe get an RX560 which while a fair bit weaker has native support.

 

I did some testing here.... https://www.notion.so/eightarmedpet/7460661cce3e4cc3b98fd2e24abe35f2?v=b97d67731f95457aa21d6d2f0deea233

Yep. I´m leaning towards the RX560. I play just a couple of hours a week and native support makes a big difference (specially if I wanna watch some 4k content). Thanks once again!
