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. Designed for GPU Cards, Also Supports Other Demanding PCIe Cards The Breakaway Box’s single x16 PCIe 3.0 slot accommodates full-length, double-width cards, and its 750W power supply supports trouble-free operation. Its single-port 40Gbps Thunderbolt 3 interface ensures the full 2750 MB/s of PCIe bandwidth is dedicated to the installed card. Why Sonnet? Sonnet maintains a working relationship with Thunderbolt and graphic cards partners, and is one of the first eGPU enclosures recommended by Apple®. Apple demonstrated eGPU connectivity over Thunderbolt 3 with Sonnet's eGFX Breakaway Box at Apple's 2017 WWDC (World Wide Developers Conference). The Breakaway Box was provided as an eGPU kit to developers to assist in the development of eGPU on Mac® computers. eGPU Breakaway Box 750ex Key Features: Includes two 8-pin (6+2 pin) auxiliary power connectors 750W power supply; supports cards requiring up to 375W of continuous power plus an additional 100W peak power Provides 85W of upstream power (useful for charging your notebook) AMD approved for the air-cooled editions of the AMD Radeon RX Vega 64, Radeon Pro WX 8200, and WX 9100 Designed to also support overclocked NVIDIA cards with high peak power requirements See Graphics Card Compatibility Chart (PDF) for List of Compatible AMD and NVIDA GPU Cards 750ex Model Includes: Integrated hub with four USB 3.2 Gen 1 Type A ports and one Gigabit Ethernet Port ***Note that updating from macOS 12.2 to macOS 12.3 creates a temporary compatiblity issue with eGPUs that we expect Apple to quickly resolve.*** Product Overview One x16 Mechanical (x4 Electrical, Thunderbolt 3 Spec) PCIe 3.0 Slot Supports One Full-length, Full-height, Double-width PCIe Card Maximum GPU card size 312mm x 160mm x 55mm; See Graphics Card Compatibility Chart (PDF) for Supported Video Cards Quiet, Temperature-controlled Fan One Thunderbolt 3 Port 0.7-meter Thunderbolt 3 (40Gbps, 100W) Cable Eco-friendly Power Features Thunderbolt Certified Mac and Windows Compatible 2-year Product Warranty Free Lifetime Customer Technical Support Designed in the USA More Ports, Additional Functionality: eGPU Breakaway Box 750ex Is your computer short on ports for basic connectivity?

How Can You Decide If an eGPU Would Accelerate Your Workflow? Learn More About How Much Power External GPU Cards Really Need Learn How Breakaway Boxes Powers On, Charge Notebooks, and Sleep Review: It was nice while it lasted... - It was nice while it lasted. This has finally died, after about 8 years of usage with an RX580 card to have an external GPU for my Mac Mini 2014 (Using TB2 to TB3 adaptor). I will not be purchasing a new one since the Mac has hardware issues now, but overall this was a good purchased. Review: Great for use with an Intel NUC. - We wanted to try out Minecraft with ray-tracing and the onboard Intel Iris graphics of my NUC i7 was obviously not going to be enough. Rather than replacing the computer, I decided to add an external graphics card using this eGPU housing. I was pleased to buy it on special offer at 345 Euro which was a great price (price seems to fluctuate quite a lot as stock comes and goes with different suppliers). The case is much bigger than I had expected, but I guess that is necessary to house the power supply and to fit the longer graphics cards. I went with a Asus GeForce Dual RTX 3060 12GB V2 OC Edition Gaming Graphics Card (DUAL-RTX3060-O12G-V2) for about 295 Euro, which fitted easily: https://www.desertcart.de/dp/B096658ZWP Noise is very low. I would say it is actually silent compared to the fans of my NUC11 i7. Build quality seems very high, with good instructions for opening the case and installing the graphics card (not that this is exactly difficult to work out for yourself anyway!). The external USB ports on the back of the unit are very useful, and mean that I have been able to get rid of a USB hub that was needed for webcam, sounds and DVD writer. All works perfectly. The result - we can now play Minecraft with way better ray tracing graphics at between 50-60 fps. Ok so the graphics might be a little held back by being in an external enclosure compared to plugged directly into the motherboard, but the RTX 3060 was enough for what we wanted. Maybe the limitations of an eGPU enclosure are only significant with faster graphics cards? So I now have a decent PC for gaming, but also a tiny NUC that I can disconnect and easily carry when I need to work away from home. Almost best of both worlds, so I'm pleased. Be sure to check the list of compatible graphics cards on the SoNNet website before purchasing to make sure it fits (but almost every card I checked seemed to be on the list). **Conclusion** I would 100% recommend, very pleased in every respect, but worth watching the price for a while and buying when it is on offer. ## Features - Boosts Graphics Performance - Connects a high-performance GPU card to your computer with Thunderbolt 3 ports.

Most NVIDIA RTX 3080s do not fit, but a few do, such as EVGA GeForce RTX 3080 XC3 Gaming and ASUS GeForce RTX 3080 TUF Gaming. For a compatiblity list of hundreds of GPU cards, see the reference pdf on the sonnettech web site. **Q: Can it support a gpu with a quadruple slot?** A: The maximum card size that will fit in a Breakaway Box is 312mm x 160mm x 55mm. If the card is larger in any dimension, it will not fit. **Q: Do they have a usb c only version of this anywhere? I don't have thunderbolt :(** A: eGPUs require a Thunderbolt interface on the computer ## Customer Reviews ### ⭐⭐⭐⭐ It was nice while it lasted... *by M***I on 16 November 2025* It was nice while it lasted.

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.co.th/products/282341241-egpu-breakaway-box-750ex-external-gpu-chassis](https://www.desertcart.co.th/products/282341241-egpu-breakaway-box-750ex-external-gpu-chassis) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-10*
