Part No. ECHO-1D-TB3 Create Expansion Echo I Desktop 1-slot Desktop Thunderbolt to PCIe Card Expansion System for Computers with Thunderbolt 4 or Thunderbolt 3 Ports Connect One Full- or Half-length, Single- or Double-width PCIe Card to Computers with Thunderbolt 4 or Thunderbolt 3 Ports For many creative pros relying on recent portable, mini desktop and all-in-one computers to get their jobs done, their computers’ onboard processing power alone is not enough. While these Mac®, Windows®, and Linux® computers include high-performance Thunderbolt ports to support peripherals, they lack PCIe expansion slots to install a specialty card that adds needed storage expansion, video or audio inputs, transcodes data, or connects to high-speed shared storage and networks. Sonnet has a solution — the Echo™ I Desktop. This professional Thunderbolt™ to PCIe card expansion system enables you to connect one up to full-length (12.28 inches long) single- or double-width PCIe card to your computer via a single cable.

We’ve put together a PCIe Cards Compatibility PDF that identifies cards conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion systems. Add a x16 PCIe Card Slot to Your Computer with Thunderbolt 4 and Thunderbolt 3 Ports, Including Mac Studio Space and Power to Spare The Echo I Desktop features one x16 PCIe 3.0 slot, enabling it to support a huge variety of cards, whether single- or double-width, low-profile or full-height. To support power-hungry cards, it integrates a universal 400W power supply and includes a 150W 8-pin (6+2 pin) auxiliary power connector for cards that require extra power (including the Avid Pro Tools | HDX). The Echo I 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! Dual Fans. Ultra-quiet Operation. Featuring dual Noctua fans, the Echo I 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 the spectrum of their noise to minimize the impact at any single frequency. To further ensure negligible noise levels, the fans are temperature-contro
