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.

Coolest and 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.

Eco-friendly Thunderbolt 3 Power Features
Thunderbolt 3 provides eco-friendly power features to help save power and energy: the enclosure powers on when your computer is on and powers off when the computer is put to sleep, shut down, or disconnected. In addition, Thunderbolt 3 Power Delivery (PD) allows the Breakaway Box to power and charge notebook computers when the computer is sleeping.
