Hello guys, 

Im pretty new to this, but am looking to build a eGPU for my HP Specter x360 15'. I have read a ton of forums and guides but seems I am still a little confused.

This project has 2 main, being able to game on my computer (Gears 5 is waiting for me 🙂 ) and spend some time building something. Therefore I would like to avoid the likes of Razer core X

As for as I have understood so for I need to find a PCIe Board (with TB3??), a Graphic Card, and a PSU, and the TB3 cable and I should be done...

Still, researching for the parts, I don't seem to find the PCIe Board, am I missing something?

Do you have any recommendations on what hardwares to get, and where?

Any installation or builds that you think could guide me?

Do you think this is possible?


thank you for your help guys!

@felipe_moreno This discussion on ADT-Link R43SG-TB3 is as close and accessible as you can get to DIY.

Consider a ADT-Link R43SG or ADT-Link R43SL + Jeyi LEIDIAN.   Skip the Jeyi unit if get a deal like this:

eGPU Setup 1.35    •    eGPU Port Bandwidth Reference Table

2015 15" Dell Precision 7510 (6th,4C,H) + GTX 1080 Ti @32Gbps-M2 (ADT-Link R43SG) + Win10 // compares M.2 vs TB3 performance

Check some of the ideas at

There's pictures of the wavlink at

Basically, you can turn any Thunderbolt 3 device with a PCIe slot or M.2 slot into an eGPU. You just need to add power.
