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

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, i5-10210uGPUs 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.

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.

Everything was awesome drivers went great but I turned it off for the night and haven't had it able to turn on since. I changed the psu and gpu to equipment that is working in my pc.

This is a good option for crypto miners that need the daisy chain option for mining with laptops or mini PCs and for light GPU aka 4070 or 7900 xt usage due to it only being TB4 capable speeds at 1080p gaming with dlss or fsr scaling. Most gamers would be better off buying a Minisfourm DEG1 having pci-e x4 4.0 speeds for a um890 or a Beelink egpu dock for a beelink AI mini Intel ultra 5 pc as it has x8 pci-e 4.0 speeds for a 4090 and 7900 xtx for a 4k 120hz 2024 lg oled g4 tv, 86 inch budget 120hz 4k lg tv, or samsung 8k 55 inch tv. Until TB5 egpu docks are made form this manufacturer or others I cannot recommend this for gaming as the lag and fps spikes can annoy alot of console gamers that are used to a 30-60 fps smooth framerate in games at 1440k or 4k.

It does work, but while you can use an external graphics card for rendering, it refuses to use its video ports. But I think that Windows 11 or having Intel integrated and dedicated Nvidia GPU in laptop and adding another Nvidia GPU causes some driver issues that are not unsolvable and are not the fault of this product.Also you may need to go a little cutty-bendy on the top cover to accomodate your GPU's screws or ports, as that seems not to be 100% standardized. My RTX4060TI 16GB MSI two-fan GPU did need customization. But please get the top cover off and cut it alone to avoid contaminating the PCB with metal shavings.One thing that is definitely wrong with it is that it did NOT come with a power supply or Thunderbolt cable or the screws needed to secure the card in place, contrary to the product description.

Worked but the lag time for the gpu was over 12 ms. Not useful for what I'm going for.

Sorry, I was unable to access the product, so I already returned this product to the seller

Works great for me. I like the small form and the on/off switch is a plus. I have this to connect a GTX 1650 to a shared mini and only turn it on when using games that are more graphically intense using a thunderbolt connection. I didn't need a big PSU (for such a small graphics card), so not having a relatively large bracket other docking stations came with in the way is fine for me. I see there are only 2 left in stock, I hope they will replenish by the time I need to replace or upgrade this setup.
