NUC8i7HVK eGPU still powered on when NUC shuts off

Jump to solution

Hi,

 

I bought the NUC8i7HVK recently and plugged in an eGPU. For some reason, when I shut down the NUC, the eGPU is still powered on and I can see the RGB lights.

 

I use the same eGPU with a laptop that also has TB3 and when I shut off the laptop, the eGPU turns off like it should.

 

I'm not sure why for the NUC, it is not turning off. I have the latest drivers for everything. The eGPU encloser is the Razer Core X.

 

Right now, the only thing I can do is just unplug the eGPU and plug back in every single day; which is annoying.

 

Thanks.

Hi,

Try this:

  1. Press F2 during boot, to enter Bios settings.
  2. In Bios: Advanced > Power > Secondary Power Settings (the R.H. panel) - disable Wake From Thunderbolt Devices
  3. Press F10 confirmed By "Y" to save settings and exit from Bios.

Hello 3000021817311.5559916495538584E12, Thank you for your response and attaching the report requested. We were reviewing more information about your system configuration and the external GPU connected to the unit. According to the product specifications, the Razer Core X Thunderbolt™ 3 external desktop graphics enclosure has its own power source. If a Thunderbolt* 3 device has its own power source, the Intel® NUC will not power off the device. This device has to be powered off separately.

HI,

 

But a lot of eGPU enclosers have their own power supply to power up the card.

 

One thing I did notice is that when I completely cut off power to the NUC (unplug power cord / turn off power strip), eGPU turns off. Is it because even when you shut down windows, the NUC itself is still providing power via its TB3 that the eGPU is sensing the PC isn't shutdown (like a USB hub)? Is it possible to completely turn off power delivery for the TB3 when you shutdown?

 

Thanks.

This worked! I guess on my laptops, the TB wake was probably disabled by default so I never noticed it.

 

Thanks for the solution.
