The Sonnet Breakaway Box 850 T5 eGPU Enclosure allows users to add real GPU power for gaming, creative work, and AI applications.
The Breakaway Box 850 T5 brings desktop GPU power to your laptop with a single Thunderbolt 5 connection. Designed for video editors, AI developers, medical imaging, and gamers, this powerful eGPU expansion enclosure lets you utilize the full potential of today’s high-end graphics cards.

Editing, rendering, color grading, animating, or creating special effects require the processing power of desktop or workstation graphics (GPU) cards to efficiently and quickly handle the demanding data processing needs. Because many popular laptops come with either integrated graphics or low-power discrete GPUs, their performance can be severely limited for these tasks. By adding the Sonnet Breakaway Box 850 T5 Thunderbolt 5 eGPU, you can connect your high-performance GPU card to your computer through a single Thunderbolt 5 cable and significantly enhance its graphics performance.
