@craftsman Thank you for the update. That is my observation as well. The computer and external GPU themselves stay asleep just fine. What keeps running during sleep is the PSU fan. The sound is not that audible.

It would require a firmware or software update to tell the PSU to sleep.

This set up can no longer complete any of the Unigene benchmarks and the few 3D game titles I have also result in crashes. It wasn't stable before but worse now. I've tested the card in a PC and it looks fine. 2D games + compute benchmarks Luxmark and Geekbench continue to work normally.

The Unigene demos will hang at some point or log me out. After crashing there is an instance of the app still running in Activity Monitor where it is consuming a lot of CPU. The app however is not running and is closed. It is just a thread stuck in the CPU.

@craftsman
testing the card in a pc, this was a very smart move by you. In this way you should be able to rule out a hardware defect. Still why wouldn't it work in MacOSX?

In an eGPU set up there are many points of failure....System APIs > Drivers > SMC > Thunderbolt firmware of the host computer > Active Thunderbolt Cable with chips in the connectors on both ends, Thunderbolt firmware of the chassis > GPU firmware > GPU hardware.

To work out where the problem is takes a lot of work. The only thing I can do is try another GPU. Everything else is not in my hands.

I've made this thread private, invisible to guest visitors. 

After very intense research, looking at other user experiences and screenshots I found that a batch of Revision ID 0x00c0 cards have an instability and reliability issue. I refunded my RX Vega which was behaving inconsistently and had Revision ID 0x00c0. I'll now purchase the Radeon VII but will first wait for the fan fix and for Apple to list it in their support article.

This thread can be deleted.

Tried Rise of the Tomb Raider. Same performance as the 1080 Ti but that's not great. It's a very badly ported title that randomly jerks and freezes even though the GPU is not overheating. 

This should not be the case, Feral ports are awesome and super optimised. I've run several Rise of the Tomb raider and it works great on any eGPU system I've tried. I've a video on my Italian channel
