## Overview

The SoNNeT eGPU Breakaway Box 750ex is a high-performance external GPU expansion system that connects via Thunderbolt 3, delivering up to 750W of power to support the latest AMD and NVIDIA graphics cards. Compatible with most Mac and Windows computers (excluding M1 Macs), it dramatically accelerates editing, rendering, and visual effects workflows. Designed for professionals seeking a future-proof, plug-and-play solution backed by a 2-year warranty and lifetime technical support.

## Description

Whether you’re editing, rendering, colour 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.

Review: Easy to set up and looks good - A nice looking box, though you need plenty of space for it. Great that the integrated power supply includes the necessary cables and that there is a thunderbolt cable to connect to my laptop. Having these makes the setup super easy.
