I have an interesting one for y’all. I mine etherium for a living which means I need a lot of those pcie x1 to pcie x16 risers to mount my GPUs. I have quite a bit of them lying around and I was wondering if I could covert one of them into an egpu. I’ve already tried gaming off of one with a 1060 3gb plugged into a pcie x1 slot on my motherboard and compared it to being plugged directly into an x16 slot. To my surprise there was no drop in performance when using the riser vs being directly connected. Now I am trying to get it to work with my laptop. I think this is possible because the part that plugs into an x1 slot that has the female USB port for the riser has no chips what so ever on it, just traces that go to the female USB port. That means I should be able to somehow find out which wires in the usb riser cable represent the pcie lanes and then solder those wires to a usb c plug. If the pcie lanes in a thunderbolt 3 interface are the same as the pcie lanes in a desktop mobo then this should work, right?

There are very low cost M.2 to PCIe adapters shown below that would allow your riser to connect to a NVME-TB3 adapter like Wavlink UTE02, JEYI Leidian, Orico TCM2T3-G40 or JEYI Thunderdock 7 mini. Then can attach to a TB3 port.

 

Of course you could plug the PCIe end of your riser to extend out a TB3 enclosure, though you might want to just plug your video card directly into the TB3 enclosure instead. Compare the best TB3 enclosure options in the Buyer Guide.

They aren't. Thunderbolt3 is not PCIe, it is an encapsulation of PCIe (and other protocols) in a Thunderbolt3 connection.

That means I should be able to somehow find out which wires in the usb riser cable represent the pcie lanes and then solder those wires to a usb c plug

All this will do is likely to fry whatever you're connecting this to. It won't work.

You need a Thunderbolt3 controller on both sides of the link, so if you want to connect an existing riser into a Thunderbolt3 device, you first need a Thunderbolt3 to PCIe adapter of some sort, like the kinds of adapters that nando4 is describing.

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

  • @yukikaze Is a 10Gbps nvme enclosure enough to run my gpu at full power?

@lock_macgregor, Since there no TB3 NVMe enclosures that are "10Gbps" I am guessing that you are looking at a USB-C to NVMe enclosure. That's not Thunderbolt, and it won't work.

Your riser only works with a PCIe connection - (M.2 Socket 1 key A+E, M.2 Socket 2 key B+M, M.2 Socket 3 key M, Express Card, mPCIe, etc.)

If your laptop doesn't have a free PCIe connection to use, then you can make one by connecting a Thunderbolt to M.2 NVMe adapter or Thunderbolt PCIe expansion chassis. In either case, you don't want to use the riser because it's only x1. You can connect a GPU to Thunderbolt using x4.
