Compatible with most Mac and Windows systems (excluding M1 Macs), it accelerates demanding tasks like editing, rendering, and color grading by offloading graphics processing to a dedicated GPU. With 8GB GDDR6 VRAM support and a sleek, easy-to-install design including all necessary cables, it’s a future-proof solution for professionals seeking to dramatically boost their computer’s graphics capabilities. ## Description Whether you’re editing, rendering, colour grading, animating or creating special effects, many of the pro applications you use rely on desktop and workstation graphics (GPU) cards to do the heavy lifting in processing data. Unfortunately, many popular computers are equipped only with integrated graphics or low-power discrete GPUs that bottleneck performance when performing these tasks. Happily, there’s a simple path to greater productivity — add a Sonnet external GPU (eGPU). The eGPU Breakaway™ Box 750 Thunderbolt 3 to GPU PCIe card expansion systems boost your eGPU-compatible computer’s graphics performance by connecting a high-performance GPU card to your computer via a single cable. Review: Easy to set up and looks good - 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. Review: Worked out of the box with my GPU. Easy to install, quiet and causing no headache. ## Features - Boosts graphics performance by allowing you to connect a high-performance GPU card to your computer with Thunderbolt 3 ports.

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. ### ⭐⭐⭐⭐⭐ Review *by Y***V on 9 March 2026* Worked out of the box with my GPU. Easy to install, quiet and causing no headache. ### ⭐⭐⭐⭐⭐ Review *by S***. on 29 October 2023* 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. ## 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.us/products/376995182-sonnet-egpu-breakaway-box-750ex-tb3-expansion-system](https://www.desertcart.us/products/376995182-sonnet-egpu-breakaway-box-750ex-tb3-expansion-system) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-24*
