The first thing I did with AMD Radeon RX Vega 56 in the AKiTiO Node was turning up the power limit to +50% and increasing the fan speed. All the early reviewers suggested doing that to get a free and easy speed boost if you don't care about Watts. Unigine Superposition benchmark at 1080p Extreme preset improved from 3283 to 3548 with this simple change. Then I tried to run it again for confirmation, and the Node shut down. It shut down under any sustained load. So I set the power limit back to default and ran 3DMark Fire Strike stress test. The Node shut down again after a few minutes, even at default settings. I managed to get it stable by lowering the GPU core voltage from 1200mV to 1000mV. Clearly this is a GPU with high power requirements!

Akitio Node with it's 400W PSU is not suitable for any Vega. Please upgrade your power supply to 650W or higher, with single 12V rail

That's too mammoth of a power requirement for a single card, isn't it...
When Akitio Node was getting ready to be released, the highest power consumption AMD GPU was R9-390X, and that enclosure can handle that.
That was way before first Vega sample became available; all eGPU OEMs required (by Intel) to list compatible GPUs, and I do not think anyone has listed Vega yet...

True!
But also who would have expected that vega would be more power hungry and more loud than a R9 290!
Edit: I would like you give us some support instead, like driver and bios updates news that users could sort out eGPU side and deal with it decently.
Would be nice if you could do so.

I am already trying to support the community as much as can (without getting fired) 🙂
Efforts to optimize Vega XConnect support are in progress. As it was mentioned few times already, drivers for Vega are only going to improve, and as soon as we have XConnect ready drivers for Vega, I will post them here.

Don't bring the "fired" argument, i have already a hard time dealing with misleading thread about Raja being fired, how bad vega is in every point and explain what is really vega, etc etc etc! 😉
Dealing with basic customers and shadow posters is an hard task, hope you guys are well aware about all the thread on usual enthusiast forum.

Trust me. It's really hard trying to support this community without crossing any red lines. There's a lot of NDAs and different contracts in place that limit what we can publicly disclose. 🙁 🙁 🙁

I managed to get it stable by lowering the GPU core voltage from 1200mV to 1000mV.
Akitio Node with it's 400W PSU is not suitable for any Vega. Please upgrade your power supply to 650W or higher, with single 12V rail
After a full day of testing I found that it requires the GPU power limit set to -50% to run games on an external 4K monitor.

Thats great to hear!
Im glad you have a graphics card you enjoy and suits your needs. 👍
I have to say this... Thanks in advance for letting me get it off my chest. LOL!
In my opinion:
ATI/AMD are smoking some serious kind asking/expecting users to carry 650+ Watts of power just for their hot running cards.
I find it absolutely ironic that Apple pushed Intel into the "Low Power" corner, yet they partner with one of the highest consumption companies out there in the GPU space.
I want to support them, but other than their top end Vega cards, I have yet to find anything compelling. (For my needs)
For the record, nVidia is not perfect either.

Would you clarify why a 650W PSU is necessary with 15W PD to the host? Power peaks measured by an oscilloscope are very realiable results:
http://www.tomshardware.com/reviews/amd-radeon-rx-vega-64,5173-17.html
I've not seen any graphs where brief peaks are over 385W with the Vega 64. And a Vega 56 should not be that power hungry.
What matters more is the Max Amps/Peak Amps of the PSU.
How can the Akitio power supply be upgraded?
