Connect Three Full-Length PCIe Cards to Computers with Thunderbolt 4 or Thunderbolt 3 Ports

The best portable, mini desktop and all-in-one computers feature powerful CPUs and include high-performance Thunderbolt™ ports to support peripherals. But they lack the PCIe expansion slots creative pros need to install specialty adapter cards that enable their workflows by adding video and audio inputs, transcoding data, and connecting to high-speed shared storage and networks. Sonnet has a Thunderbolt solution — the Echo™ III Rackmount — a professional Thunderbolt to PCIe card expansion system. Via a single cable, connect three (up to) full-length (12.28 inches long) PCIe cards at the same time to your Mac®, Windows®, or Linux® computer with Thunderbolt 4 or Thunderbolt 3 ports.

Technical Notes
  • While the Echo III Rackmount features a 40Gbps Thunderbolt interface, some Windows computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps.
  • Second Thunderbolt port supports USB 3.2 Gen 1 (5Gb) or Gen 2 (10Gb) devices when connected with proper cable or adapter (sold separately).
  • When set to HDX compatibility mode, PCIe slots operate in PCIe 2.0 mode and the chassis’ bandwidth is limited to 1750 MB/s.
  • Power supply will operate as low as 90VAC, with linear power derating from 400W @ 115VAC to 320W @ 90VAC.
  • Full performance requires the use of the included or comparable 40Gbps Thunderbolt cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables. Full performance supported by any Thunderbolt 4 cable.
  • ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt 3 cables.
  • Mac Compatibility:
    • Mac (M series) with PCIe cards that have compatible drivers
    • Mac (Intel®) with Thunderbolt 3 ports
    • Mac (Intel) with a Thunderbolt 2 or Thunderbolt 1 port with an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter plus a Thunderbolt 2 cable (both sold separately)
    • macOS® 10.12.6+
    • macOS Sonoma compatible
  • Windows Compatibility:
    • Windows computer with Thunderbolt 4 or Thunderbolt 3 ports
    • Windows 10
    • Windows 11 22H2 build 22621.819 and newer
  • Linux Compatibility:
    • Linux computer with Thunderbolt 4 or Thunderbolt 3 ports
