2018 Mac Mini [8th,6C,B] + RTX 2060 Super @ 32Gbps-TB3 (Razer Core X) + Win10 [adonalsium]  

Hey everyone! Really excited to be able to post a working build. I hope it helps some people! 🙂
macOS 10.14.6 is loaded but cannot drive the eGPU as Apple-Nvidia have no RTX Nvidia drivers.

System Specs:

1. Late 2018 Mac mini – i5-8500B/UHD Graphics 630 iGPU/20GB RAM/128GB SSD
2. Philips 246E (Screen: 23.6in., Native resolution: 1920x1080, Aspect Ratio: 16:9, Refresh Rate: 60Hz, HDMI, DVI, D-Sub (VGA), 3.5mm output jack)

OS: (bootcamp) Windows 10 Home - version 1809, build 17763.864

eGPU Hardware: Razer Core X + MSI GeForce RTX 2060 Super Ventus OC. I use the TB3 cable included with the RCX.

Installation:

1. eGPU + GeForce 2060 Super Ventus OC plugged into power strip, but power switch set to off, TB3 cable plugged into eGPU but unplugged from far left TB3 port on Mac Mini. 
2. Mac Mini is off, connected to monitor via HDMI.
3. Power on Mac Mini, boot to Win10.
4. Once logged in, turn on eGPU power switch.
5. Plug TB3 cable into far left TB3 port.

Comments:

I am blown away by what the eGPU has brought to gaming. I appear to be fortunate that things worked seemingly "out of the box".

I'll say that what I have to do each time I shut down the Mac Mini and reboot into Win10 is:

• completely unplug the eGPU from the Mac Mini,
• make sure the power switch is off,
• make sure the HDMI cable is connected to the Mac Mini.
• I then log in to Win10,
• turn the eGPU power switch on,
• then plug the TB3 into the far left TB3 port on the Mac Mini. 

This seems to work consistently. Thanks for letting me post this build, I really hope it comes in handy for people!
