@paul_chen That looks like it would work great for enclosures like the Samsung X5 that have the Thunderbolt port on the same side as the M.2 slot. The cable doesn't advertise Super Speed 10 Gbps. One reviewer says 5 Gbps max. But maybe it will still work (Thunderbolt is 20 Gbps per line but works with up to 5 of my 90° adapters chained together that advertise 10 Gbps).

I have found a solution for my fit problem but it's on a slow boat from China so maybe I can try it in November.

An alternative to R43SL is the R43UL, R43UR, R43ML, or R43MR. One of those could work with your M.2 enclosure and allow you to have the Thunderbolt port on the same side as the GPU display outputs like with the non-cabled M.2 to PCIe x4 adapters that I'll use.

For my M.2 enclosure, one of the M variants would be required to have the Thunderbolt port facing the rear with the graphics cards ports - R43MR to place M.2 enclosure in front of the GPU fans, and R43ML to place enclosure on the PCB (back) side of the GPU. In either case, the M.2 size of the R43Mx is only 2242 so an extension would be required to install in a 2280 only M.2 enclosure.

Here's pictures of each of the R43_STX series items. The first one seems like the best one for my enclosure. The width of the enclosure only needs to be about 2 inches (or slightly more) to accomodate these. 2 inches is probably the minimum width for an internal power supply (A Mean Well power supply without enclosure). I haven't received yet the M.2 extensions for the 2242 R43Mx but I'm sure they can work without (just use some tape to keep them in place). I used lengths of 10 cm for the GPU fan side and 5 cm for the GPU PCB side but I suppose 5 cm would have worked for the GPU fan side as well.

@joevt

you should set up a wiki guide, the pictures of the variants are useful along with controller direction

I managed to get the mean well supply working, however, I'm unclear how to jumpstart the rig if I omit the 5v connection to the ADT board and just connect the 12V and common connectors directly from the output of the power supply. When I wired it up to a pico psu (which comes with a floppy connector), and jump the atx, it works. Here is what it looks like.

What does 5V have to do with jumpstarting?

If you have 12V from the Mean Well then there's no jumpstarting required. You have a volt meter? What voltage does it say? Compare the 12V from the pico and from the Mean Well.

Did you connect both grounds of the ADT-Link? I don't think the ADT-Link requires 5V. Can you see anything on the ADT-Link that looks like it's connected to 5V?

okay i had 12v plugged into the wrong side of the floppy connector, i swapped it and it now works without pico psu!!!

@paul_chen Luckily that side of the floppy connector is not used, otherwise you could have blown something up! 🙂 I think you need an on/off switch somewhere. Would you put it on the 120V side or the 12V side? The PCB is from the Samsung X5? It's much larger than the PCB from the NVMe drive I used. What's the dimensions? Mine is 35x92 mm (45x95 mm with the aluminum base).

I got some other parts. First, an x4 to x16 riser which eliminates the need to cut a non-open ended x4 slot, and adds 19 mm of height so the Thunderbolt port will clear the bottom of the graphics card, and you can use a full sized floppy power connector (instead of the low profile one I showed before), and you can place a 40 mm high power supple under the GPU.

Riser rear

If 19mm is too high (you're not putting a power supply under the GPU and you want to minimize volume), then you can use one of the R43_STX series items like I showed before, but this time position the M.2 underneath. Add some pressure to fold the cable tighter (minimize height) but not too much pressure because that will cause loss of Thunderbolt signal and a strange noise. The flexible cable also lets you move the M.2 enclosure in all 6 directions for the perfect position. In this next picture, I used the 10cm long R43MR (I think 5cm would be better). The R43ML would also work but requires a few more millimetres on the back plate side of the GPU (for single cable fold and for floppy power connector) or requires a few more millimetres in height (3 folds of the cable instead of two for the R43MR).

R43MR under

The R43ML and Rd43MR require M.2 extenders. Here's what they look like with the R43ML:

Back to the solution that uses the fixed M.2 to PCIe x4 slot adapters where there wasn't enough room to connect a cable to the Thunderbolt port,
https://egpu.io/forums/which-gear-should-i-buy/thunderbolt-3-external-drive-slot-m-2-ngff-adapter/paged/2/#post-66727

I have received a couple M.2 Extender Adapters which can shift the PCIe slot by 9 mm which gives plenty of space for a 90° USB-C connector (and only adds 2.3 mm of height which is less than the height allowed by the PCIe bracket underhang). I used a Dremel with cutting disk to shorten the extender (cuts like butter) so it only includes the hole for securing a 2280 M.2 device. Below is a picture showing before and after trimming the excess.

I used the micro sata cables M.2 to PCIe x4 adapter and low profile floppy power connector (linked in earlier posts). The white M.2 to PCIe x4 adapter also works - it moves the USB-C connector inward more but that is unnecessary. The current position is fine because it is within the volume required to contain the top of the PCIe bracket (if you don't want the PCIe bracket to stick out of your case). Also, it gives more room behind the PCIe slot under the graphics card.

The final 90° USB-C connector makes slight contact with the backplate of the GPU. A flexible USB-C extension cable would be a better solution (like the one found by @paul_chen), if you can find one that can do 40 Gbps Thunderbolt.

This might be a silly question, forgive me if it is! Isn't there any performance loss in using a x4 PCIe slot? Or is it really because thunderbolt is only using the 4 PCIe lanes anyway?

This looks like a very interesting project and I might be doing something similar myself as well soon!
