## 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).

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.
