Step Up to 40Gbps Thunderbolt 3
Sonnet designed the xMac mini Server (XMAC-MS-A) Thunderbolt 2 to PCIe card expansion system to be easily upgraded to 40Gbps Thunderbolt 3. Simply replace the existing Thunderbolt interface board with the upgrade board, and then your chassis will instantly support higher performance, and connect to your Thunderbolt computer without the need for an adapter.

Upgrade Instead of Adapting
Why adapt when upgrading offers more? With the Thunderbolt 3 upgrade card installed you get:

  • Easy to Install 40Gbps Thunderbolt 3 Upgrade Card – Replaces Existing 20Gbps Thunderbolt 2 Interface Board
  • Improves Performance with High-Bandwidth PCIe Cards – Provides 30% More Bandwidth (Up to 1750 MB/s)
  • Two Thunderbolt 3 Ports
  • Compatible with Thunderbolt 3, Thunderbolt 4, and Thunderbolt/USB4 computers
  • 0.5-meter Thunderbolt 3 (40Gbps) cable
  • ThunderLok 3 Thunderbolt Connector Retainer Clip
  • 2-Year Warranty

Package Contents
(1) Thunderbolt 3 upgrade card
(1) 0.5-meter Thunderbolt 3 (40Gbps) cable
(1) Thunderbolt 3 cable lock(7)
(1) Documentation

  • Hardware: Thunderbolt 3 Upgrade Kit for xMac mini Server (Thunderbolt 2 Edition)
  • Warranty: 2-year
  • External Connectors: Two Thunderbolt 3 ports
  • Operating Temperature: 0˚C to 35˚C (32˚F to 95˚F)
  • RoHS Compliant: Yes
  • Sonnet Hardware Compatibility: xMac mini Server (Thunderbolt 2 Edition) (Part No. XMAC-MS-A)
  • Notes:
    • Check compatibility listings on this page for currently supported systems. Other systems will be added once certified.
    • Connection to a computer with Thunderbolt 3 ports requires the use of a Thunderbolt 3 (40Gbps) cable, like any of Sonnet’s Thunderbolt 3 cables, for full performance.
    • While each Thunderbolt 3 upgrade card features a 40Gbps interface, some computers equipped with Thunderbolt 3 use an implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps. The MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) also has this limitation in the two right-hand Thunderbolt 3 ports, while offering full performance from the left-hand ports.
    • Second Thunderbolt 3 port supports Thunderbolt and Thunderbolt 2 devices on Macs when used with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter, sold separately.
    • Second Thunderbolt 3 port supports USB 3.1 Gen 1 (5Gbps) or Gen 2 (10Gbps) devices when connected with proper cable or adapter (sold separately).
    • One 4K monitor directly supported. Two 4K monitors requires either a 4K monitor with multi-stream transport support (DP out), or a Thunderbolt 3-to-Dual DisplayPort adapter. 5K monitor support requires a Thunderbolt 3-to-Dual DisplayPort adapter.
    • ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt 3 cables; Sonnet 1-meter Thunderbolt 3 cables require ThunderLok 3L.
    • Windows computers require the latest firmware (BIOS) and other drivers to support this product. Check with your computer manufacturer for update information. Not all Mac-compatible PCIe cards are also compatible with Windows. See the PCIe Card Thunderbolt Compatibility Chart for details.
  • Sonnet Hardware Compatibility: xMac mini Server (Thunderbolt 2 Edition) (Part No. XMAC-MS-A)

  • Mac Compatibility:
    • Mac with Thunderbolt/USB4, Thunderbolt 4, or Thunderbolt 3 ports
    • Macs with Thunderbolt 2 or Thunderbolt ports with the Apple Thunderbolt 3 (USB C) to Thunderbolt 2 Adapter
    • macOS 10.12.6+
    • macOS Sonoma compatible

  • PC Compatibility:
    • PC with Thunderbolt 4 or Thunderbolt 3 port(8)
    • Windows 11 (Future Release 23H1+required), or 10
