@the_livy Can you share the block diagram of the NUC7? I'd love to use my NUC7i5BNH by getting Power Delivery through the eGPU enclosure. Currently I need to use the NUC's own AC power adapter.
Oh sorry, it seems the diagram I found was from the NUC8 only, I didn't think it would have changed between the two.
Sadly they are different though, see 1.1.4 for the diagrams in both:
NUC7 (Page 21) / NUC8 (Page 6)
to me, it looks a lot like power supply over TB3 should be possible on the NUC8?
edit: Chapter 1.8 sadly only states 5V 3A output on the Thunderbolt port: "The boards support ThunderboltTM 3 with up to 40 Gbps of data throughput, one 4k (60Hz) monitor output, USB3.1 (Gen 2) connection and charging capabilities up to 5V at 3A via the back panel USB Type C connector." (see page 16 for the NUC8) – that's a real bummer, would have been nice to have, I wonder why they didn't make the NUC's capable of that, especially with the misleading block diagram of the NUC8. Sorry for bringing up false hopes!

Thank you for sharing the links to the block diagrams. I agree it looks misleading in the NUC8. There should be arrow/s showing the flow of current. The Block Power provides charging to USB peripherals through the rear USB-C port and the yellow USB-A port in the front.
I tried connecting my NUC7 to the AKiTiO Node Pro's 60W PD Thunderbolt 3 port. It was not able to power on without the AC adapter connected through the DC input port. I even tried again when the Node Pro was fully active while connected to a MacBook Pro through the 15W Thunderbolt 3 port.
