Sonnet 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.

Recently my laptop dock died and I needed something to drive the 2 external monitors connected to my Acer Aspire 5 (A515-57-760X) which has a Thunderbolt 4 port. Since I have a few extra Nvidia GPUs laying around, I wanted to give an eGPU a chance.Wow! It was very simple to set up. Just install the video card in the case, plug into the laptop and install the latest Nvidia drivers. Now I'm able to render videos in Davinci Resolve quicker, video playback is smoother and best of all.... all my screens sleep properly and resume as expected.When/If I decide to upgrade from my RTX 2070 Super to an RTX 30xx or RTX 40xx card for even faster Davinci renders, it will be as simple as install the new card, update drivers and go!

Does the job. A bit overpriced

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 Pro2. Dell XPS 13 9305 and 73903. Lenovo ThinkPad P1 Gen 34. AMD 5500XT GPU5. Nvidia 1060 GPU6. Four Acer 27" 1440p displays1. 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.

I got the Sonnet USB-hub Thunderbolt eGPU enclosure to replace the comparable Razer USB-hub enclosure I've used for the last couple years with my... I want to say NVIDIA GTX2060 Super, but I'm not going to pull it to check.The good: The Sonnet is quick, easy, smaller, lighter, more stable, bigger power-supply, and less-bloatware-pestering than the Razer. *. (that's an explicit major asterisk)*The Bad: I could only really use the Sonnet for a few hours. Because, you see, my laptop is a HP Spectre x360 (circa winter 2019). And around about BIOS update F.26 (and unresolved at present in F.30), HP introduced, into (from the sound of multiple support threads) their entire laptop line that shares this BIOS spec, a major issue with Power Delivery over Thunderbolt (keep in mind their newer laptops only charge over Thunderbolt). Basically, a whole broad category of devices more than capable of providing the required charging wattage no longer successfully charge HP laptops. Even if the factory power brick is plugged in at the same time. The Razer enclosure can, at least 80% of the time when it's not flaking out, successfully keep my laptop charged while I work. The Sonnet worked flawlessly for the short time I used it, while costing me about 10% battery every 30 minutes. The first day I used it, I didn't start from a full charge, and my entire system went into power-critical shutdown before lunchtime.Needless to say, while I WANT to be using the Sonnet for the stability and simplicity, it's going to be a non-starter until either HP fixes their laptop BIOS or I move to a different work laptop.

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.

It is a solid piece of equipment for using an external GPU with a Windows or Mac. I haven't tested Linux yet. The extra ports and ethernet is fantastic too.
