## Description

Part No. GPU-750WEX-TB3 Pro Power Graphics – Add a High-performance Video Card to Create Your Own Personal eGPU Workstation Whether you’re editing, rendering, color 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. 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?

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
*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.
