- 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 Thunderbolt Compatibility Chart for details.
