eGPU Breakaway Box 750ex - External GPU Chassis

No issues or hassles. The directions had good pictures to follow along. I use this for business (no gaming) for zoom meetings, lots of open tabs, and six monitors while having the flexibility of a laptop. The reviews here on Amazon were a little intimidating, however I found the installation of this eGPU and video card to be straightforward plug-n-play and the product to be excellent as advertised. It was easy enough to do myself without needing the manufacturer's support desk. I added 64Gb RAM to my laptop and a Radeon R7 350 HD7750 4GB to this eGPUex. The internet port and 4 usb ports on this eGPUex model eliminated the need for a separate dock to have just one usb thunderbolt cord to my laptop. To have a clean desk, I used a simple under desk laptop mount. I also used a pc under desk mount. I combined two monitor stands for three monitors each on a single extended pole. I added a reinforcement plate for my standup desk for the mount which gives good stability. I used adhesive clips and adhesive cable ties to manage all the cables underneath my desk. I also got a pebbles sound speakers so I wouldn't need a headset and Bluetooth for mouse, keyboard to not need a docking station and reduce the number of wires.

This is a great product. I fit mine with a Rtx 3060 Ti. I have an Intel tiger lake with Xe graphics and they both function on the laptop screen. Like if you max out the external, the internal will start picking up. eGPUs in general can be kinda finicky though. I have an infrequent problem where my laptop will drop the eGPU to save battery and going full tilt the break box can't quite keep my battery topped up. I had the luxury of adding a second charger and didn't have any more issues. Upgraded to 5 stars as I found out I had some configuration issues causing my problem.

I am posting this review to all of the EGPU enclosures that I tried in the hopes that it might help someone else that's trying to make a purchase decision. I'm ranking these from most favorite to least favorite. My primary goals are to be able to run 4x 1440p external monitors and I want the unit to be super quiet and reliable. I tested each with the following equipment: 1. 2019 16" MacBook Pro 2. Dell XPS 13 9305 and 7390 3. Lenovo ThinkPad P1 Gen 3 4. AMD 5500XT GPU 5. Nvidia 1060 GPU 6. Four Acer 27" 1440p displays 1. Cooler Master MasterCase EG200 - while the most expensive out of the bunch, it is my favorite due to best compatibility, reliability, and lowest noise level in my experience. This one also seems to have the best build quality and easiest to replace the PSU later if I ever want to. Also includes a built in stand for my laptop. 2. Razer Core X Chroma. Great build quality but the case fan and PSU fans are both far too loud for my liking. I also could not get the ethernet port to work with my MacBook Pro 16" but that worked fine with my Windows laptops. The PSU and fan also seems harder to change if I ever want to do that in the future. 3. Sonnet Breakaway Box 750ex. Great feature set but not clearly not built as well as the Cooler Master or Razer and more importantly I could not get it to work at all with any of my equipment so worthless to me. 4. Sonnet Breakaway Box 750. Same story as #3 but thought perhaps I just had bad luck with the 750ex. Nope! Could not get it to work with any of the equipment listed above.

Finally pulled the trigger on a EGPU and the Sonnet Breakaway Box has been great. While the Radeon 6800 barely fit, it did fit after a little bit of finagling. Very quiet even while gaming and provides a nice boost while gaming, more than doubling my fps in some games, compared to the MacBook Pro's built in Radeon 5500m. Only issue is opening and closing the enclosure is not the smoothest, but rarely needs to be done and no internal HD connectivity for a SSD so I am using an external HD though one of the provided rear USB ports. My configuration is a MacBook Pro 16" with an intel i9 CPU and 5500m GPU, an Asus ROG 43" ultrawide 3840x1200, and the Sonnet Breakaway Box 750ex with a Sapphire Radeon 6800 16gb Pulse GPU.

I bought this hoping that I would be able to hook up an external GPU to my Premiere Pro hardware accelerated video rendering. However, due to Apple's brain-damaged policy on not supporting NVIDIA graphics cards, all you can use are AMD GPUs which are not well supported by Adobe, and give you little to no improvement in the performance of your graphics processing. This might be good for gaming. I don't know. I don't game on my Mac. Do not buy this for your mac if you want to improve your video rendering. Instead: sell your mac and build a good PC, and then buy a decent NVIDIA card and simply install it in the PC case. Problem solved. Speaking of my Mac, I bought it so I could upgrade to a decent video editing platform. Looks like Mac isn't the computer for doing that any more. I hate to say that Windows--the awful and the ugly--just has better hardware support. I'm kinda regretting dumping the thousands of dollars into this stupid machine. But I guess that's what happens when it takes 5 hours to render a 24 minute video--in between the moments where you're just praying to God that the render is correct and you won't have to do it all over again to fix some dumb problem.

Worked out perfectly to add egpu, network and USB ports to my onexplayer s1. Currently have an AMD Vega 56 installed with no problems. Love the ability to upgrade GPU as needed.

Had an issue with the power supply. It was DOA on arrival. Replaced it and it works great.

Works as advertised with no issues.

Worked out of the box with my GPU. Easy to install, quiet and causing no headache.

Fonctionne parfaitement, ma carte graphique RTX 4060 ti 16gb rentre parfaitement malgré ça taille. Ce qui a amélioré largement mon pc du côté gaming. Franchement je le recommande 🙂.

A nice looking box, though you need plenty of space for it. Great that the integrated power supply includes the necessary cables and that there is a thunderbolt cable to connect to my laptop. Having these makes the setup super easy.

Great package. The seller was very supportive and helpful. Excellent egpu setup for supporting AI/ML development needs.

Recibí el producto con claras señales de haber sido manipulado previamente. El empaque estaba abierto, los sellos de seguridad venían violados y las protecciones de plástico de las entradas de video estaban incompletas. Falla técnica (Dead on Arrival): Al conectar el equipo, este no encendió en absoluto. Ante el riesgo de un cortocircuito, me preocupó la posibilidad de quemar mi GPU. Pruebas de descarte realizadas: Retiré mi GPU y la probé directamente en mi PC, confirmando que afortunadamente sigue funcionando sin problemas. Para descartar un problema de cableado, probé el equipo nuevo con un cable diferente conectado a la fuente de poder, pero siguió sin recibir energía. Conclusión: Es un producto defectuoso con una falla eléctrica grave de origen. Resulta inaceptable y una completa pérdida de tiempo que desde fábrica o almacén envíen un equipo dañado y en condiciones de haber sido abierto previamente. Solicito la devolución inmediata.
