What is the chance that the coming Vega Nano card/future vega 56 mini itx card could make due with the PSU on the Aorus gaming box? The mini cards usually have less power consumtion right so perhaps a 450W PSU will be sufficiant?

AORUS' PSU can handle 150W worth of GPU. This is due to the technical limitation of 1x 8-pin power cable. Any GPU with a TDP of more than 150w should have either 2x 8 pin adapters or 1x 8pin and 1x 6pin.
I do believe that at present, the 1070 is the biggest (in terms of TDP) GPU that can be handled by the Aorus.
RX 56 is 210w, so it must have 1x 8pin + 1x 6pin - therefore I don't think this particular eGPU can handle it. Go for a bigger bugger

.That should be 180w TDP, more than normally possible with 1x 8-pin connector. Which might suggest that the 1080 is actually underclocked or otherwise limited... or that Gigabyte found it suitable to exceed normal specs with their particular build (since they can QC everything in there).

Now that the Vega nano is out let’s tlak about it. There are 8 pin to 8+6 pin adapters so that is not really an issue. So is it feasible to upgrade the aorus box with a powercolor Vega 56 nano???

Wait, doesn't the PCIe bus provide an additional 60W?
