Product information

Description

Sonnet Echo III Silver Steel 1 is an external PCIe expansion chassis in a silver steel housing with an integrated 400 W power supply. It provides three PCIe slots (one x16 and two x8) and a Thunderbolt interface to connect up to three full‑height, single‑width PCIe cards or a combination of one double‑width and one single‑width card to a computer with Thunderbolt 3 or Thunderbolt 4 ports. The chassis supplies auxiliary power to installed cards, supports automatic power on/off with the host computer, and includes a Thunderbolt cable and a Sonnet ThunderLok 3 connector retainer.

Advantages

The Echo III Rackmount supports a wide range of non‑GPU PCIe cards including video capture, audio DSP, host bus adapters, Ethernet, and storage controllers, enabling professional audio/video, editing, and compute workflows without modifying the host system. Built with a rugged 2U steel enclosure and quiet cooling (Noctua fans rated at 17 dBA), it combines durability and low noise for studio and rack environments. Dual Thunderbolt ports provide a 40 Gbps interface with the ability to daisy‑chain peripherals while the integrated 400 W power supply and 75 W auxiliary power capability deliver stable power for multiple expansion cards.

Suitable for

  • Connecting video capture and transcoding cards for professional post‑production
  • Adding audio DSP or Pro Tools / HDX compatible cards to a Thunderbolt‑equipped system
  • Installing high‑performance network or storage controller cards (10Gb/25Gb Ethernet, SAS/SATA host bus adapters)
  • Extending PCIe capability for compact desktops, mini PCs, and laptops

Key specifications

  • Enclosure: Steel 2U rackmount housing, silver finish
  • PCIe slots: Three slots (one x16, two x8); supports up to three full‑height, single‑width cards or one double‑width plus one single‑width card
  • Power supply: Integrated 400 W power supply with 75 W auxiliary power support
  • Interface: Thunderbolt 3 / Thunderbolt 4 compatible, 40 Gbps throughput
  • Thunderbolt ports: Two ports (one for host connection, one for peripheral daisy‑chaining)
  • Cooling: Low‑noise fans (rated at 17 dBA)
  • Compatibility: macOS, Windows 10, and Linux systems with Thunderbolt 3 or Thunderbolt 4 ports

How to use

Install the required PCIe cards into the chassis slots according to their physical size and the supported slot configuration (up to three single‑width full‑height cards, or one double‑width plus one single‑width card). Connect the Echo III to your computer using the included Thunderbolt cable and secure the connection with the ThunderLok 3 if desired. Power on the chassis; it can power on or off automatically with the host computer. Ensure that any necessary drivers or vendor software for installed PCIe cards are installed on the host system before use.

Usage recommendations

Place the chassis in a well‑ventilated rack or workspace, allowing clearance for airflow to maintain low fan speeds. Use the included Thunderbolt cable and ThunderLok 3 to prevent accidental disconnection, and install vendor‑provided drivers and firmware updates for connected PCIe cards to ensure system stability and compatibility.
