TREBLEET 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

Worked straight out of the box with an AMD Ryzen 7 7840HS/8845HS Mini PC from AliExpress. Simply connected a standard ATX computer power supply (24 pin + 8 pin) to the dock, then a 8 pin power plug to my RX6600/RTX 3060, connected to its USB-C 4.0 port and powered both GPU and PC on. Windows 11 detected the GPU and it was fairly smooth sailing during driver setup. GPU-Z reports the GPU running thru the LH7740 Thunderbolt 3 chip is at PCIe 3.0 x4 link speed which is maxing out the capabilities of the dock (there are no Thunderbolt 4 chips available yet). Read the other review for more helpful hints, the other reviewer does recommend eGPU.io for help and support. You must ensure that the device you wish to use it with has Thunderbolt 3/4 support or has USB 4.0. If your device doesn’t support Thunderbolt, you’re outta luck.

Not sure what some of the other reviews are going on about - literally the largest 3-slot card with a huge fan housing/shroud is completely clear of the slot on this device. Working perfectly fine under Linux and Windows (and of course Apple killed off any chances of having decent graphic card support when they lost the capabilities of Nvidia support a while back, and again with AMD when they shot themselves in their feet by failing to support any decent GPUs whatsoever under their M1/M2/etc devices). If this isn't working for you, and you didn't somehow get a defective item shipped to you (more likely damaged by the courier, who love to destroy things/ditch deliveries in bushes/etc), then you likely are lacking adequate Thunderbolt device support on your system. Pretty happy with the performance of this product; stable-diffusion works well, as well as Yuzu/other emulators at 4K@120hz, and gaming in general.

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.

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.

As the headline suggests, while the product technically works, the enclosure is not deep enough to hold the GPU properly. It causes the GPU to tilt lengthwise, causing the GPU to not seat properly, lowering performance to unacceptably low levels (my Radeon 4600 performed worse than a GTX 1060 from limited testing, when it really, really shouldn't). Additionally, concerns over the rigidity (or lack thereof) have arisen. The slightest nudge causes the GPU to rock back and forth a bit in its seat. I have since removed the GPU over concerns of snapping at the area where the GPU was seated.
