Is your computer short on ports for basic connectivity? Step up to the eGPU Breakaway Box 750ex to add four 5Gb/s USB 3.2 Gen 1 Type A ports to connect peripherals, plus an RJ45 Gigabit Ethernet port for a wired network connection. The 750ex features a dual Thunderbolt controller design, enabling it to support both peripherals and GPU card through the single Thunderbolt connection to your computer. 4K to 8K Workflows – Connect Two or More Breakaway Boxes Many task times on supported applications—such as Adobe Premiere Pro, DaVinci Resolve, and Maxon Cinema 4D, to name a few—can be cut significantly with one eGPU Breakaway Box connected. But, for computers with multiple Thunderbolt ports, times can be slashed when two, three, or four Breakaway Boxes are employed. Connecting one or more eGPUs can multiply your computer’s graphics processing power, enabling it to handle 4K, 5K, 6K, and 8K workflows more efficiently. Coolest & Quietest Add-your-own-card eGPU System Available With its large variable-speed temperature-controlled fan that quietly and effectively cools the installed card, the eGPU Breakaway Box can be comfortably used in noise-sensitive working environments. Compatible with Thunderbolt 4 Windows Computers eGPU Breakaway Box 750ex is fully compatible with Thunderbolt 4 Windows computers and was purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum performance. Supports Latest GPU Cards Review: Ideal Business Setup - 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 desertcart 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. Review: Works great when it works - 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. ## Features - Boosts Graphics Performance - Connects a high-performance GPU card to your computer with Thunderbolt 3 ports.

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. ## Frequently Bought Together - Sonnet eGPU Breakaway Box 750ex - External GPU Chassis - Cable Matters [Intel Certified] 40Gbps Thunderbolt 4 Cable 3.3ft with 8K Video and 240W Charging - 1m, Compatible with USB4, Thunderbolt 3 Cable and USB-C - Cable Matters [Intel Certified] 40Gbps Active Thunderbolt 4 Cable 6.6 ft with 100W Charging and 8K Video - Fully Compatible with USB C/USB-C, USB 4 / USB4, and Thunderbolt 3 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/273188817-egpu-breakaway-box-750ex-external-gpu-chassis](https://www.desertcart.pt/products/273188817-egpu-breakaway-box-750ex-external-gpu-chassis) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-18*
