Work Faster. Game Harder.
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 harness the full potential of today’s high-end graphics cards. Install the GPU of your choice, connect it to your compatible Windows laptop or small form factor (SFF) computer, and instantly unlock the performance needed for smooth 4K gaming, fast rendering, and demanding AI workflows. With triple-width GPU support, ultra-quiet operation, and upgrade flexibility, Breakaway Box 850 T5 is built for serious work — and serious play.

Transform Your Windows Laptop or Small Form Factor Computer Into a Near-desktop Graphics Workstation
Are you a video pro? Many of the applications you use — whether to edit, render, color grade, animate, or create 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. The good news? There’s an easy solution for boosting your productivity — just add a Sonnet Breakaway Box 850 T5 Thunderbolt 5 eGPU to connect your high-performance GPU card to your computer through a single Thunderbolt 5 cable and significantly enhance its graphics performance.

Local AI for Faster Processing and Enhanced Privacy
So, you’ve purchased a laptop or SFF computer loaded with RAM; a super-fast, high-capacity SSD; and a high-end CPU, but you’re not sure what it can do using the onboard graphics processor. For AI related tasks, maybe not as much as want it to do. But, when you connect Breakaway Box 850 T5 and install one of the latest GPU cards, you can run local AI apps faster to perform the tasks you need without paying for a subscription or per transaction fees.

LLM Libraries
Run Large Language Model (LLM) apps such as LM Studio Ollama, and GPT4ALL without needing to be online, and keep your data local.
Graphics
Edit and generate images with applications like Stable Diffusion and Flux.1.
Audio
You can also auto-generate text to speech, reduce noise, repair distorted audio, and even generate music using applications such as VoiceCraft, Krisp, and Ace-Step.
Graphic-Intensive Gaming
You don’t need to drag around a gaming laptop to enjoy high-performance gaming. Just connect Breakaway Box 850 T5 with your graphics card installed to instantly add the GPU power you need, when you need it. This solution will boost graphics performance on laptops and small form factor computers that may otherwise fall short for demanding games. You can output the enhanced graphics to one, two, or more monitors — or even your laptop’s built-in display. Best of all, the GPU you install is upgradeable, so you can easily stay current with the latest generation high-performance graphics tech — something gaming laptops can’t offer.

Thunderbolt 5: Tomorrow’s Performance. Today.
Breakaway Box 850 T5 features the performance and qualities you expect from a Thunderbolt 5 eGPU plus the added connectivity and functionality you need. Transform a single cable connection from your computer into a powerful graphics and processing upgrade with a built-in Thunderbolt 5 dock. With up to 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — you'll revolutionize your productivity.

Broad GPU Card Compatibility with Power to Spare for Future Graphic Cards
Built to handle the most power-hungry triple-width GPUs, Breakaway Box 850 T5 is a plug-and-play upgrade that boosts performance for video production, demanding games, and AI workloads. It supports Thunderbolt-compatible GPUs including AMD Radeon RX and Pro, Intel ARC and ARC Pro, and NVIDIA GeForce. Each GPU generation brings more power — and higher power needs. With its robust 850W power supply, the Breakaway Box 850 T5 easily supports today’s top-tier GPUs and is ready for tomorrow’s more demanding cards.

More Power. Many Ports. Built-in Thunderbolt Dock.
Is your computer short on ports for basic connectivity? Breakaway Box 850 T5 includes a built-in Thunderbolt 5 dock, enabling it to support additional peripherals, wired Ethernet, and a GPU card through the single Thunderbolt connection to your computer.

Connect and Power an Additional Thunderbolt Device
The Thunderbolt 5 peripheral port enables connection of an additional Thunderbolt 5, 4, or 3 peripheral — or a USB-C device — and provides 15W to power it.
Even Faster Transfers Across Existing Ethernet Cabling
Featuring a 5 Gigabit Ethernet port, Breakaway Box 850 T5 supports a 5 Gbps link over common Cat 5e (or better) cabling when used with a compatible Ethernet switch or NAS with 5 Gb Ethernet support, saving you the cost of another adapter. You can get great performance gains — 500 percent the speed of Gigabit Ethernet — without rewiring! In case you’re connecting to a switch or NAS without 5Gb Ethernet support, the Sonnet eGPU also supports 2.5 Gbps, 1 Gbps and 100 Mbps link speeds.
Quick 10Gbps USB Ports for Bus-powered Devices and Gaming Peripherals
Breakaway Box 850 T5 includes three USB 3.2 Gen 2 (10 Gbps) Type A ports to support super-fast USB NVMe SSDs at up to full speed, and each port provides up to 7.5W, ensuring bus-powered devices will operate without fail. They're also perfect for connecting gaming mice, keyboards, and headsets with USB-A ports.
Cool and Quiet – Add Your-Own-Card eGPU Enclosure
With its large variable-speed temperature-controlled fan that quietly and effectively supports maximum cooling of the installed card, Breakaway Box 850 T5 can be comfortably used in noise-sensitive working environments.
