Supports Every Thunderbolt 4 Compatible, Non-GPU PCIe Card
Echo III Desktop supports every Thunderbolt compatible, non-GPU PCIe 1.1/2.0/3.0 card available including video capture and transcoding; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb, 25Gb or Ethernet; SSD storage; and other specialty types to your system.

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 3 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.

Backward Compatible with Older Macs. No Thunderbolt 3? No problem -- the Echo III Desktop is also compatible with Macs with Thunderbolt 2 ports when used with the bi-directional Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt cable (both sold separately).

• Adds Connectivity & Capabilities: Connects up to three high-performance non-GPU PCIe cards via a Thunderbolt 3 cable to your computer lacking expansion slots.
