Sonnet - 'eGPU Breakaway Box 750W'

Thunderbolt™ 3 to eGPU Card Expansion SystemsWhether 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 and 750ex 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.
750W Power Supply

Future-proof UpgradeWith each new generation of GPU cards, users can look forward to a step (or leap) forward in performance. Less predictable is how much power they will require to operate—better performance frequently requires increased power. For eGPU users, power consumption can be a concern. Don’t limit your future card choices—choose a Sonnet eGPU Breakaway Box 750 or 750ex. Equipped with 750W power supplies, these Sonnet chassis easily support the highest power demands of latest GPUs and have plenty of extra power to support GPU cards from generations to come.
Thunderbolt Certified eGPU Breakaway Box

eGPU Breakaway Box 750• Includes two 8-pin (6+2 pin) auxiliary power connectors.

Key Features

Boosts Graphics PerformanceConnects a high-performance GPU card to your computer with Thunderbolt 3 ports.

Cuts Application Task TimesEnables GPU acceleration to significantly improve editing, rendering, color grading, animation, and special effects performance.

750W Power SupplySupport the power requirements of the latest compatible GPU cards; future-proof design handles higher power requirements of cards to come.

Supports Many of the Latest GPU CardsIncludes AMD Radeon VII, RX, RX Vega, Pro W and Pro WX models; and NVIDIA GeForce RTX series, TITAN, and Quadro models.

Multi-eGPU Acceleration SupportConnect two, three, or four eGPU Breakaway Boxes to slash task times on supported applications.

Supports Non-GPU PCIe CardsSupports Thunderbolt-compatible full-length, full-height, single- or double-width cards –perfect for pro audio I/O and DSP cards and pro video I/O and transcoding cards.

Quietest Configurable eGPU System AvailableLarge built-in, variable-speed, temperature-controlled fan quietly and effectively cools whatever card you install.

Choice of ModelsBoth models support the same GPU cards, include the same power supply, and provide the same portable computer charging support; the 750ex adds additional connectivity.

Single-Port 40Gbps Thunderbolt 3 InterfaceEnsures full 2750 MB/s of PCIe bandwidth(2) is dedicated to the installed card.

Thunderbolt CertifiedIncludes AMD Radeon VII, RX, RX Vega, Pro W and Pro WX models; and NVIDIA GeForce RTX series, TITAN, and Quadro models.

Mac and Windows CompatibleCompatible with Mac and Windows computers with Thunderbolt 3 ports.
Performance Comparisons
Application eGPU Performance ExamplesConnecting a desktop or workstation GPU card delivers a significant graphics processing boost to the top video editing, visual effects, and modeling applications, cutting rendering times and enhancing VFX and color correction workflows.

Multi-GPU Support

4K to 8K Workflows – Connect Two or More Breakaway BoxesMany task times on supported applications—such as Adobe® Premiere® Pro, DaVinci Resolve™, and Maxon Cinema 4D™, to name a few—can be cut significantly with one eGPU Breakaway Box connected. But, for computers with multiple Thunderbolt ports, times can be slashed when two, three, or four Breakaway Boxes are employed. Connecting one or more eGPUs can multiply your computer’s graphics processing power, enabling it to handle 4K, 5K, 6K, and 8K workflows more efficiently. Plus, a computer’s onboard discrete GPU also contributes to the aggregate performance.
Thunderbolt 3 Performance

Designed for GPU Cards, Also Supports Other Demanding PCIe CardsThe 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(2) is dedicated to the installed card.
Quiet & Effective Cooling

Coolest & Quietest Add-your-own-card eGPU System AvailableWith 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.
Accelerated Gaming Performance
Graphic-Intensive Gaming SupportThere’s no need for you to carry a heavy, loud, and hot-running gaming laptop to have a great gaming experience—just plug in a Breakaway Box and add the GPU power you want when you need it! A Breakaway Box is ideal for empowering graphic-intensive gaming on an Intel® processor-based MacBook Air® or 13-inch MacBook Pro®, Ultrabook™ and other thin/light notebook computers that otherwise would deliver a poor gaming experience. Accelerated graphics can either be displayed on one, two, or more external monitors, or on your notebook’s own display panel(4). Best of all, you can upgrade the GPU card in the Box to keep up with the latest in GPU technology (unlike with gaming laptops).
