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!

This is my 2nd eGPU enclosure. There's now even less alternatives for this niche solution and have had minor issues: turning it on *after* logging into Windows is more reliable, occasionally need to disable/re-enable the GPU driver. Granted, some issues will be down to the GPU but just saying that the 'eGPU experience' is still far from smooth.Having said that, this enclosure is the closest to 'plug and play' you could get. I installed my GPU into the enclosure, connected all the cables, turned the enclosure and my laptop on, installed the GPU driver, and it worked. The USB ports at the back are great, allowing me to connect all my peripherals and the GPU to the laptop, and charge it, with the one cable. The price doesn't make it an easy purchase but you can judge that yourself. The enclosure does power down when your laptop does but I turn it off manually due to one of those issues I mentioned.

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.
