Being one of the younger people in my office and having even a small amount of knowledge about computers means that I do part time IT work. One of the perks is that whenever people at work get new computers I get to take the older ones. This time my machine was next up on the list for replacement, so my current work computer became my personal computer. I’ve had a PSU and GPU lying around for a couple of years and it seem like the right time for and eGPU build. This is my first eGPU build and I new to the community.

After extensive research, I found nando4’s M.2 vs TB3 test. This build used components that were most similar to my own and it served as my guide. Ali Express wouldn’t let me order things for some reason and everything came from Amazon. While things were more expensive that I would have liked, all of the parts arrived in two days. Total cost ~$170 after tax.

System specs 

2018 15" Dell Precision 7520

Intel Core i7-7820HQ (Quad Core 2.90GHz, 3.90GHz Turbo, 8MB 45W)

16GB, 2x8GB, DDR4 2666MHz

Intel® HD Graphics 630

NVIDIA Quadro M1200 w/4GB GDDR 5

Windows 10 20H2

eGPU Hardware

Enclosure: ADT-Link R43SG (50cm) M.2

eGPU: Zotac GTX 980 Ti Amp Extreme

NVME-to-TB3: Wavlink WL-UTE02

PSU: EVGA SuperNova NEX 750B

Hardware pictures:

Coming soon

Installation steps:

  1. Attached eGPU to ADT-Link R43SG (50cm) M.2
  2. Connected PSU 24p + 4p (CPU) to ADT-Link and 2x8p from PSU to eGPU
  3. Attached ADT-Link R43SG M.2 adapter end to Wavlink WL-UTE02 NVME-to-TB3 and secured with screw (I plan to get some heat shrink tube)
  4. Boot Win10
  5. Disable the dGPU via Device Manager -> Display adapters -> (highlight) dGPU, then select View -> Devices By Connection. Right-click disable the PCIe port directly above the dGPU.
  6. Disabled automatic driver installation Control Panel -> System and Security -> System -> Advanced System Settings -> Hardware -> Device Installation Settings -> Select No -> Save Settings
  7. Download Nvidia drivers
  8. Restart in Safe Mode
  9. Use DDU to Remove any existing Nvidia drivers (Quadro) and shutdown
  10. Plug in eGPU M.2 to TB3 into TB3 port, and boot Win10
  11. Wavlink appeared in Thunderbolt attachments: Approve the device -> Set to Always connect
  12. Install latest Nvidia Geforce eGPU drivers

I don’t know if Step 6 was necessary because the PCIe port was disabled.  Maybe someone more experienced can comment on that.

Step 11 was my only hang up. My computer saw that the Wavlink was attached to the TB3 port but wasn’t allowing it to connect. This caused my driver installation to fail because it said there was no recognized device. The problem continued until I manually told it to always connect.

Comments This went remarkably smoothly. The only hiccup was the TB3 software requiring the device to be approved. Even if I'm losing 30+% of performance to the TB3 connection, the GTX 980 Ti is still better then the M1200. I am still able to use the HDMI port on my computer, programs need to be told to use the eGPU in the NVIDIA Control Pannel.

Last week I was playing the Diablo II: Resurrected Closed Beta on the lowest graphic setting possible and getting 20-30 FPS with the M1200. I’ll update the post with my new FPS when the Open Beta starts this weekend.

@nando4, I'll add some imgur links soon.

Also, thanks for your guide. It was super helpful.
