I've a Thinkpad X1 3rd generation tablet, which has thunderbolt 3 slots. I am thinking about getting an external GPU enclosure since the thunderbolt 3 protocol itself supports interfacing with PCIe. What I'm looking for is a basic thunderbolt 3 to PCIe adapter. Basically just the cable with the necessary controller board.

I already have a GTX 1060 and a power supply, which is why I thought maybe I could get away cheaper if I just bought an adapter without all the extra stuff. I also don't have a set budget, but 300$ or more is a lot for just the enclosure in my opinion.

    These are good questions, but we specialize more at finding something that works, rather than explaining the underlying specifics. Try asking this question on electronics.stackexchange.com, and post a comment to the URL so we can follow it. – Alex Jan 2 at 12:44
  • I was redirected here. I think the question if actual adapters exist still fits in here. I'll post the rest elsewhere – Jeffrey Jan 2 at 17:09
  • Yeah it's more complicated than you're imagining, you need a controller on the other end, along with (usually) power delivery, other I/O, etc. Some are more simplistic than others, but the suggestion of just wiring a cable to a riser won't work AFAIK. That said, if you could rewrite your question in the form of a hardware recommendation, that'd be good. Else, try superuser. – JMY1000 Jan 5 at 19:10
  • @JMY1000 right thanks for the recommendations. I changed my post accordingly – Jeffrey Jan 5 at 21:25
  • What laptop do you have? Do you already have a GPU you want to use with the enclosure? If so, what? If not, what's your total budget? – JMY1000 Jan 6 at 22:13
