Echo III Desktop Thunderbolt 3 Three-Slot PCIe Card Expansion System

Connect Three Full-length PCIe Cards to Computers with Thunderbolt 3 or Thunderbolt 4 Ports

For creative pros using the latest portable, mini desktop and all-in-one computers in their workflows, onboard processing power alone is not enough to get the job done. While these computers include high-performance Thunderbolt™ 3 ports to support peripherals, what they lack is PCIe expansion slots to install specialty cards that add needed video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet has a solution—the Echo™ III Desktop—a professional Thunderbolt to PCIe card expansion system that enables you to connect three (up to) full-length (12.28 inches long) PCIe cards at the same time, via a single cable.
