3-slot Desktop Thunderbolt to PCIe Card Expansion System for Computers with Thunderbolt 4 or Thunderbolt 3 Ports
Connect Three Full-height, Half-length+ PCIe Cards
Although Mac®, Windows®, and Linux® computers with Thunderbolt™ 4 or Thunderbolt 3 ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. The computers lack the PCIe expansion slots needed to install specialty cards that add video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet’s Echo™ Express SE IIIe is a compact, desktop Thunderbolt to PCIe card expansion system that enables you to connect three professional PCIe cards to your computer at the same time, via a single Thunderbolt cable.
Nearly Every Thunderbolt-Compatible, Non-GPU PCIe Card Supported
Smaller than the 3-slot Echo III Desktop, the Echo Express SE IIIe is still large enough to support nearly every Thunderbolt compatible, non-GPU card available. With its three x8 slots, the SE IIIe supports PCIe 4.0, 3.0, PCIe 2.0, and PCIe 1.1 cards up to 7.75 inches long. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a list in our supporting PCIe Card Thunderbolt Compatibility Chart (PDF). There you’ll find cards identified as conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion system.

Aluminum Enclosure. Auto Power On/Off.
Three PCIe 3.0 Slots for Demanding Professional Needs
Echo Express SE IIIe’s PCIe 3.0 x8 slots support three half-length+, full-height, single-width PCIe cards, or one single-width card plus one double-width card.
Double-width?
Some specialty cards, such as RME’s HDSPe MADI FX, Blackmagic Design’s DeckLink 4K Extreme, and the Lynx AES16e 50, include a daughter card that mates with and provides additional external connections to the main card.
Power to Spare
Echo Express SE IIIe includes an auxiliary PCIe power connector, enabling you to install a card requiring extra power, such as the AJA® Kona® 5 or Blackmagic DeckLink 4K Extreme 12G, and Bluefish444’s Epoch and KRONOS SDI cards.
40Gbps Thunderbolt Cable and ThunderLok 3 Included
