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.

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.

Mostly works in my win max 2 2023 7840U, and RTX 3070 but in order to get PCIE 4.0 x4 speeds I need to use the m.2 adapter. If I use the onboard oculink port then I need to drop the PCIe speeds to 3.0 x4 which equates to about 15-20% performance loss in the real world. For the price it’s something I’m willing to deal with, especially since I can 3D print a cover for the bottom oculink adapter. Your mileage may vary on other computers, or even this same computer, as I’ve seen reports of stable pcie 4.0 x4 on other Win Max 2 2023s. I tried different power saving settings and every tweak I could find in every bios version as of may 2024 but the behavior was consistent across all of them - as soon as the GPU was accessed for acceleration in 4.0 speeds the computer would either lock up completely or blue screen, unless I used the m.2 adapter. Then it works perfectly.

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.

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 .

Works perfectly on use it on my HP elitedesk 805 g6 to add a egpu

Ran for almost a year with a GPD Win 4, periodically crashed until my 3090 died. Would not recommend.

This product aloud me to hook up a gpu to my older quad core Intel mini pc to allow it to be more elevate in the modern era of gaming. I used a gpu that had lying around dx12 card. I saved money from not having to by a new pc. You will need a pc power supply. Luckily I had a spare one. Good luck.

Product works with my gpd win 4 2024, for people struggling to get it to work here's some tips 1. There's a microscopic on and off switch on the board, make sure it's switched on ( i found it after scratching my head for ages ) 2. If you are trying to connect an nvidia card and get code 43 look up nando4 fix You are welcome

Really happy with this purchase, it comes with the oculink cable and wifi slot to oculink connector but I bought another one with extender through the nvme slot. Much better than the noisy overpriced Aoostar. The build is combined with RTX 5070 and Corsair RM750e modular PSU for a clean build. Zero noise build, the fan only goes up if temperature passes 50 degrees Celsius. The GPU is turn on and off according to the laptop power state. Plug in, Power up, Install latest Nvidia Driver, Gigabyte control center, code 43 script. I write low level CUDA for a living, so here’s some extra info: - nvidia-smi shows 2 GPUs (my original laptop GPU rtx 3050Ti and this one) - 2 GPUs can communicate through PCIe, I tested a NCCL code for vector addition on 2 GPUs and it worked. - CUDA Code can compile with sm_120, and run no problem. Pytorch recognizes 2 GPUs and set the 5070 as GPU 0. Nsight compute works with debugging and uses 5070 if the code is compiled with sm_120.

Klappt super mit einer RTX3060. Ich habe im Laptop eine GTX 1660ti. Hier gab es Probleme. Google hat dann geholfen mit [SCRIPT] nvidia-error43-fixer. Das hilft wenn die eGPU ständig deaktiviert wird. Bei mir muss ich außerdem beim starten das HDMI Kabel entfernen um auch den Laptop Bildschirm nutzen zu können.

Used it with N100 mini PC . worked with older hd4770 , failed to work with RTX 2070. Problem is the hd4770 is worst than the integrated graphics. Update: Ended up making the 2070 work on a ryzen 9. So the problem was the N100
