GMKtecAD-GP1 External GPU Docking Station, eGPU Enclosure with AMD Radeon 7600M XT GPU Graphics Card, HDMI2.1, DisplayPort2.0, Oculink, USB4, eGPU Dock for Mini PC Laptop Notebook Game Console

I spent $20 on a M.2 PCI X4 to Oculink adding it to my mini-PC. This allowed me to use the Oculink connection on this GMKtec AD-GP1 External GPU Docking Station, with AMD Radeon 7600M XT GPU with great success.If you use the USB 4.0 with video support the FPS performance Will be fine. But a great deal of small gaming freezes while playing. This is because the video is converted to a format the USB can use, then converted back, causing intermittent lag making this a deal breaker. Oculink has given me very solid, low lag, consistent FPS gaming.My Mini PC and others show up in search queries regarding the automated onboard graphics switching to EGPUs and back. This causing boot issue inconsistencies. Yes, that's not a comment specific to this manufacturer and performance of this EGPU but directed @ some Mini PCs that will need Oculink connectivity added (M.2).This will help. First, with pc and EGPU power disconnected plug in the Oculink cable, and all others (HDMI, USB, etc.) to both units. Second, The EGPU must be plugged in first as your Pc only responds to what is there as the BIOS fires up (POST). If the EGPU is not connected and powered up first, it cannot be seen when you hit the power button on the PC.Third, this process still holds true with future EGPU connection issues. So, all connections/cables remain connected. Pull power from both units. Long press PCs "power on" button "without power connected" to drain any residual BIOS startup memory. Connect power to the EGPU, then the PC, and finally press the power button. Your BIOS has seen a new PCI X4 connection and will have responded to it. If you intentionally switch from EGPU to onboard graphics or back hold down the "SHIFT" key while you click shut down. This will Delete the KERNEL (operating sys, instructions as to what hardware and drivers to preload) and allow it to be rebuilt on boot up.This unit is and has been a 5 Star purchase. Deciding to buy it you will consider the above. You would prefer to go into this with a Mini PC that has Oculink built into it. If you choose my way (add M.2 Oculink) just make sure you have a general understanding of BIOS POST and the operating sys. Kernel

I wanted to set up my GMKtec M6 for Linux gaming (ChimeraOS or Bazzite) because I’m not a big fan of Windows. It kinda worked, but I kept crashing after a few minutes of gaming. I reached out to support, and they gave me some suggestions, but they mostly suggested I try Windows for stability. I decided to give it a shot and set up Windows and the eGPU. It’s working great now! I might try reinstalling Bazzite in a few months if GMKtec supports Linux better. In the end, the gaming set up is much smoother on Linux (no Windows nonsense!), but actual gaming is more stable on Windows. I ended up spending a few days trying to beat Windows into submission. Did you know that even though it’s 2025, there’s no easy way to stop shortcuts from showing up on your desktop? Sigh. Anyway, Julian at GMKtec support was super helpful, so I really appreciate the support I got with this purchase. Thanks, GMKtec!

This is my first eGPU and GMKTEK purchase. For context, I purchased this to pair with my Legion Go + an OLED portable monitor (UPERFECT 02: OLED 3k 16 inch).My initial impressions were the build quality, which feels very premium. The size is also very compact and the design is minimalistic/subtle. It doesn’t throw RGB at your face or look ridiculous.When plugging it into the Legion Go it was Plug N Play on the internal screen. I was instantly able to use the 7600m XT rather the Z1Es integrated GPU. The performance increased via TB4 and the internal screen was about 15-40% depending on the game.Now, the tricky part was using the external monitor. Unfortunately the stock drivers on the Legion Go don’t play nice with eGPUs and external monitors. This isn’t a fault of GMKTEK, but a fault of Lenovo and their drivers. You will need to install stock 780m drivers on your LEGO to use this and an external monitors. It’s time consuming but isn’t difficult. There’s lots of tutorials online.Once you get the external setup working, the performance jump is quite significant. You will get higher performance on an external monitor rather the internal (bandwidth issue on the LEGOs screen). I was getting anywhere from 30% to nearly 100% more performance. For example, in Cyberpunk 2077, I could achieve nearly 100FPS on 1920x1200 with AMD fluid frames and all settings on high with RTX. That’s amazing for the price point!All in all, I highly recommend the product if you’re looking for an eGPU. If you’re using a handheld and want to use an external monitor, make sure you read up on some guides to help navigate some potential errors.

I am really happy with the device but my power brick stopped working, anyone know what is the size the of DC connector? I found many brand with the same input/output but not sure about the connector size?
