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™ to GPU PCIe card expansion system boosts 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 interface ensures the full 2800 MB/s of PCIe bandwidth is dedicated to the installed card. Why Sonnet? Sonnet maintains a working relationship with Thunderbolt and graphic cards partners, and is one of the first eGPU enclosures recommended by Apple®. Apple demonstrated eGPU connectivity over Thunderbolt 3 with Sonnet's eGFX Breakaway Box at Apple's 2017 WWDC (World Wide Developers Conference). The Breakaway Box was provided as an eGPU kit to developers to assist in the development of eGPU on Mac® computers. eGPU Breakaway Box 750 Key Features: Includes two 8-pin (6+2 pin) auxiliary power connectors 750W power supply; supports cards requiring up to 375W of continuous power plus an additional 100W peak power Provides 85W of upstream power (useful for charging your notebook) AMD approved for the air-cooled editions of the AMD Radeon RX Vega 64, Radeon Pro WX 8200, and WX 9100 Designed to also support overclocked NVIDIA cards with high peak power requirements See Graphics Card Compatibility Chart (PDF) for List of Compatible AMD and NVIDA GPU Cards Product Overview One x16 Mechanical (x4 Electrical, Thunderbolt 3 Spec) PCIe 3.0 Slot Supports One Full-length, Full-height, Double-width PCIe Card Maximum GPU card size 312mm x 160mm x 55mm; See Graphics Card Compatibility Chart (PDF) for Supported Video Cards Quiet, Temperature-controlled Fan One 40Gbps Thunderbolt Port 0.7-meter Thunderbolt Cable Eco-friendly Power Features Thunderbolt Certified Mac and Windows Compatible 2-year Product Warranty Free Lifetime Customer Technical Support Designed in the USA 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.

How Can You Decide If an eGPU Would Accelerate Your Workflow? Learn More About How Much Power External GPU Cards Really Need Learn How Breakaway Boxes Power On, Charge Notebooks, and Sleep Review: Beste Entscheidung für volle Grafik-Power im Notebook - Ich war ja durchaus skeptisch, ob das klappt: Aber zumindest eine Geforce RTX 3060 kann ihre Leistungsfähigkeit in diesem Setup voll und ganz ausspielen.

I have 3 1440P screens running forza 8 with the 4050 I had to have it run it at 4320x1080 and really reduced graphics to get 30-40 fps. I put in a GeForce RTX 4070 and now can run the game 7680x1440 with high grahics setting depending on the track get usually 50-70 fps. Benchmark result is 41. From reading and watching reviews about egpus. I was worried it would not be any better then the internal 4050 but I am happy that it is almost twice as fast now and it can handle the 1440P screens. The only reason I didn't give it 5 stars is because of the expensive price tag. ## Frequently Bought Together - Sonnet eGPU Breakaway Box 750 - External GPU Chassis - Not Compatible with M1 Macs - MSI Gaming GeForce RTX 3060 12GB 15 Gbps GDRR6 192-Bit HDMI/DP PCIe 4 Torx Twin Fan Ampere OC Graphics Card --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/298505839-sonnet-egpu-breakaway-box-750-external-gpu-chassis-not-compatible](https://www.desertcart.co.uk/products/298505839-sonnet-egpu-breakaway-box-750-external-gpu-chassis-not-compatible) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
