Chenyang Oculink SFF-8612 to PCI-E 3.0/4.0 M.2 M-Key to SFF-8611 Host Adapter for eGPU/GPD Win Max2 External Graphics Card & SSD

Hooked up a 750w psu and a 750ti to my kids dell optiplex aio 2nd m2 port and it works like a charm. Integrated graphics are a no go when it comes to gaming, even an old 750ti stomps hd 630 Intel Totally worth it, and it was a fun process installing and building an enclosure.

It works! The oculink connector to your computer comes out straight up/out from the board, so keep in mind the orientation of your m.2 connector. For a laptop, this means it comes straight out the bottom, not the side or back.

I received this today, briefly tested it and it works great! I briefly tested an old GTX 970 on this pcie x16 board with the included m.2 adapter and a different m.2 adapter, they both worked. Also, tested with this with an m.2 to m.2 extension cable. This did NOT work. I did not check how many pci lanes are actually running, but I will update here once I do. And I just threw this together rather quickly (zip ties and scrap metal bottom). I have ordered an external gpu bracket to hold it all better.

This thing works. I attached it to a Aoostar Gem10 through the Oculink port and powered it with a standard PC power supply. This powered my Nvidia 1070ti with no issues and was able to deliver full video support to my mini-PC. I have not tested the NVMe adapter, but i'm sure that works as expected. I didn't really need it for that use case. I bought this for $50 so I would say it was the best value for the money.

So far, this is the only thing that let me connect my ASUS ROG Strix Scar 18 (2025) with RTX 5090. I tried Aoostar AG02 and Minisforum DEG1 with no success. They gave me unstable PCIe 1.1 connection. I used this Chenyang Oculink adapter with the JMT ADT-F9G F4Q to amplify the signal on the laptop side. Then the laptop and RTX 5090 FE connected with each other via staggering PCIe 5.0 x4 connection not even PCIe 4.0.

Has Quality issues. Was not boxed properly (loose) and arrived damaged with broken capacitor. Was missing the Occulink cable. Do not recommend!

Let's drive the very first important point here; a WIN MAX 2 is NOT the only device you are allowed to use for this. I bought this for my GPD WIN MINI, which has an oculink port, and this has worked fine. Personally, for $40 dollars the price is very reasonable, especially considering that oculink cables can be expensive. The only gripe I have with this is the board; there is no supporting bracket or piece of anything underneath the actual board to give it some strength. When I connect my graphics card to it, I feel as though I'm going to snap the board because of how thin it is. Also take into consideration that the board does not have those locking clips to give an audible sound that the gfx is connected, you have to provide a little force to make sure it's connected with this product. A little scary, worried that I am going to break the actual board trying to connect or disconnect, but time will tell. Overall this is a must buy if you have oculink and want to use an EGPU. I pair this with a 6700xt to a MINI and get decent performance. For the most recent game example, Hellblade 2 gets me around 68fps on high, 1080P, 120hz. Compare this to TB4, I get around 54fps overall. Oculink definitely gives a nice little bump .

Worked well
