Mini eGPU Enclosure Compatible with Thunderbolt 3/4, USB4 40Gbps External GPU Dock Station, Compatible with NVIDIA/AMD PCIe, PD 85W Charging Support, Daisy Chain, DC/ATX/SFX Support

Be sure your cables are within spec if you are not using the included one and that your laptop or TB3/4/USB4 device is eGPU ready. If this enclosure doesn't work at all it's something you're doing wrong. Reference egpu.io for help. The JHL7440 chipset is widely used in other similar eGPU products. If you happen to get a defective one I would at least attempt to get a replacement before rating 1 star. This is one of the nicest complete packages I've seen. I am using a USB4 dock in the passthrough TB port with no measurable performance impact. I'm getting the rated 32Gbps, and readings go over that limit often. (This is limited to device side not the enclosure.) The only issues I had was the screws; my unit came with all internal screws loose and some had fallen out and rattling inside the shell. You can easily tighten them yourself so this was a minor inconvenience. Just had to mention. In conclusion: The shell design can accommodate almost any size GPU. Keep in mind when using the passthrough TB to not use any display inputs with the passthrough TB (such as a HDMI port on hub; this causes iGPU/dGPU from laptop to render output, and not the eGPU which takes up bandwidth.) Connect all monitors if possible to the eGPU and disable the laptop display to get the best performance. Only keep laptop display enabled if your laptop allows you to assign the i/dGPU to the laptop display. Do not route any rendering to a display NOT directly connected to the eGPU. It will reduce performance by a bit. JHL7440 chipset is the highlight. Very fast and responsive. No crashes or BSOD. You will likely BSOD if you disconnect the cable without dismounting. Especially while playing a game. So I wouldn't recommend that. Overall, do your research and enjoy eGPU life! This is a good product.

I bought this eGPU dock as an experiment to see what a thunderbolt 3 laptop could do with an external graphics card. Set up was easy, I used an old power supply, connected the motherboard and CPU connectors to the dock. I first tried an old 1080ti GPU. I used two VGA connectors from the power supply connected to the GPU. When I plugged the thunderbolt 3 cable in, and turned the dock on, it downloaded its own driver. I verified using the thunderbolt control panel on my laptop. I did not get a display at all, so I went and got the latest Nvidia driver installed. The monitor came to life. I next tried my current GPU in my desktop, a 3080ti. It was able to run a 3440x1440@180hz, and the new Dell U4025WQ at 5120x2160@120hz simultaneously. This was nice becuase my thunderbolt 3 ports could only run 5120x2160@30hz. Lastly I tried a 3050 low profile card with 2 DP 1.4a, and 2 hdmi 2.1 connectors. It was able to run 4 monitors. The hungriest setup I tried was 5120x2160@120hz, 3440x1440@180hz, 1920x1080@180hz all at the same time. It worked no problem. I did not try any demanding games or rendering with this though. This dock is great if you are like me and want desktop like monitor support from your laptop. The dock charges my laptop over the thunderbolt connection which is nice. I did not see that in the description anywhere so I assumed it wouldn’t. Hardware: Laptop: HP Elitebook 840 G7, i5-10210u GPUs that worked: 3080ti, 1080ti, 3050 low profile. (I had to remove a bit of metal from the dock shell with a dremel and drill to fit the low profile card, this is my only complaint). If this dock works for a long time it will be well worth the money.

I got this dock because I found it cheaper used. It works finein terms of being a functional eGPU board, but it has no support brackets for stabalizing the GPU (see the video). I'm going to make due with it, but I'm going to have to put together some sticks to make a stabilizing bracket myself. It might not matter if a desk never moves, but one accidental bump and you might damage a GPUs connector pins. I use a walking pad which means I shake the desk more while walking and working, so this isn't acceptable at all. This should be a deal breaker for most people: it simply isn't worth risking damage to a valuable GPU in this dock without modifications.

Gets the job done, but leaves a lot to be desired. I installed an xtx 7900, and the card says over to one end because there's NOTHING securing it to the eGPU enclosure other than pressure between the pins. Now I have to design a custom bracket.

Great value, allows me to crunch numbers with my laptop using an external graphic card, I.e. NVIDIA. Super easy to use, must have Thunderbolt to work. I have this connected to a Dell laptop using a docking bay with Thunderbolt (WD19TB). I have an ATX power supply capable of driving the GPU. Applications like handbrake are much faster now. Also, can run CUDA based application. Seems very stable, design is such that the card is exposed. Compatible with system automatically. As for stability, take care to power down carefully, do not let the card be knocked out as it may damage the device - it is fragile. It would be good if it were in a box to protect the GPU card.

Had to return this product. This enclosure can not hold the GPU without wobbling as it holds the GPU only at its slot. There are plenty of chances to snap the card's contacts when you try to plug the PCIE cables to GPU as there is nothing to hold it firm. Also, wobbly GPU is unstable when in use and may cause system crash which wouldn't be easily understandable.

Plugged it in, installed the Nvidia app and it just worked.

I have so far bought 2 of this unit for my son's with laptops. Works like a charm without a hassle.
