3-Slot Desktop Thunderbolt 3 to PCIe Card Expansion System
Connect Three full-length PCIe Cards to computers with thunderbolt 3 portsFor 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.
2750MBs PCIe Bandwidth
The Thunderbolt 3 LinkPlugged into one of your computer’s Thunderbolt 3 ports, the Echo III Desktop system enables you to connect professional PCIe cards (three full-height, single-width cards, or one double-width card plus one single-width card).

400W Power Supply
Three PCIe 3.0 Slots Plus Power to SpareThe Echo III Desktop features one x16 and two x8 PCIe 3.0 slots(1), enabling it to support a wide variety of cards at the same time. To support really power-hungry cards, it integrates a universal 400W power supply and includes a 75W auxiliary power connector for non-GPU cards that require extra power, including the Avid Pro Tools | HDX. Designed without a power switch, the Echo III powers on and off automatically with the connected computer, saving energy in the long run. With no power switch, you can’t forget to turn off the system!
Ultra-Quiet, Dual Fan Cooling Solution
Dual Fans, Ultra-quiet OperationFeaturing dual Noctua fans, the Echo III Desktop is designed to deliver ultra-quiet operation so that it can be comfortably used in noise-sensitive environments. Rated at 17.1dBA—below the 20dBA ceiling prescribed for use in recording and broadcast studios—the fans spread their noise spectrum to minimize any single frequency’s impact. To further ensure negligible noise levels, the fans are temperature-controlled, automatically speeding up and slowing down smoothly as needed, and the enclosure is engineered to optimize airflow over the installed cards to effectively and efficiently cool the system.
Included Cable & Locking Mechanism
Sonnet Thunderbolt 3 Cable & ThunderLok 3Sonnet includes a 0.7-meter Thunderbolt 3 (40Gbps) cable that transfers data at Thunderbolt 3’s full 2750 MB/s PCIe bandwidth. In addition, Sonnet provides a ThunderLok 3 Thunderbolt connector retainer clip(2) that prevents accidental cable disconnections—just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
ThunderLok AdvantageSonnet Thunderbolt expansion systems are designed with Thunderbolt ports that include a threaded mounting holes for securing Sonnet's ThunderLok retainer clips that prevent accidental cable disconnections.
Fastest External Interface AvailableThe Echo III Desktop features a 40Gbps Thunderbolt 3 (USB-C®) interface that delivers up to 2750 MB/s of PCIe bandwidth, enabling it to support 4K video capture and processing cards at high frame rates, multiple audio DSPs, and 25GbE and dual-port 10GbE network cards at full performance.
Backward Compatible with Older MacsNo 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).
Compatible with macOS 10.12.6+ and macOS BigSur, Windows 10 and Linux Kernal 5.0+
