3-slot Desktop Thunderbolt 3 Expansion System for PCIe Cards

Connect Three Full-length PCIe Cards to Computers with Thunderbolt 3 Ports

For pros working in the creative fields, a computer’s processing power alone is not enough to get the job done. A prime example is the latest MacBook Pro®, which, while offering great performance, lacks the PCIe expansion slots necessary to support specialty cards that connect pro video and audio inputs, transcode data, and connect to high-speed storage and networks. Instead of slots, these computers include high-performance Thunderbolt™ 3 ports to support peripherals. Sonnet’s Echo™ Express III-D (Thunderbolt 3 Edition) is a pro-level, desktop Thunderbolt™ 3 to PCIe card expansion system that enables you to connect three full-length PCIe cards at the same time.

The Thunderbolt 3 Connection

Through a simple Thunderbolt 3 connection, add professional PCIe cards (three full-height, single-width cards, or one double-width card plus one single-width card) including video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controllers.

Every Thunderbolt 3 Compatible, Non-GPU Card Supported

Echo Express III-D supports three single-width, full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt 3 compatible, non-GPU PCIe 1.1, PCIe 2.0, and PCIe 3.0 card available. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a list in our supporting . There you’ll find cards identified as conforming to Thunderbolt technology requirements, and organised by fit and power compatibility with specific expansion system.

All Around Smart Design

Aluminium Enclosure. Auto Power On/Off.

Echo Express III-D is wrapped in a rugged, yet lightweight aluminium outer shell, resulting in a system light enough to carry without weighing you down, yet sturdy enough to securely protect the installed PCIe cards. Since Echo Express products automatically power on and off with your computer, there is no power switch on the chassis, ensuring you don’t waste energy by forgetting to turn it off.

Three PCIe 3.0 Slots, No Compromise

Sonnet’s Echo Express III-D supports three full-size PCIe cards, up to 12.28 inches (full-length) long. The III-D integrates a universal 300W power supply and includes a 75W PCIe power connector for cards that require supplementary power, such as the Avid Pro Tools|HDX. Even with all that power, the III-D is enviro-friendly; it automatically powers on or off whenever the connected computer powers on (or wakes), or powers off or sleeps, respectively.
