The Thunderbolt PCIe expansion chassis have been tested and certified by Apple and Intel for Thunderbolt compatibility. However, in order to use this device, a compatible PCIe card must be installed. Also, that card's driver must be compatible with requirements for Thunderbolt technology (e.g. hot-plug support and recovery from sleep).

Please download the latest drivers for your PCIe card from the corresponding manufacturer's website before attempting to use the card in the external Thunderbolt PCIe expansion chassis.

If a card is not on the compatibility list below, that does not necessarily mean that it is incompatible, it just means that we have not had the opportunity to test it in our lab.

  1. Full-length cards are not supported
  2. Chelsio T5 cards require driver version 1.10.11 or later
  3. NVMe drives require macOS 10.13 or later (learn more about NVMe and AHCI)
  4. The connector can physically not be plugged into the last port at the bottom of the PCIe card
  5. The power cable is not compatible (requires 3rd-party 6-pin PCIe female to female adapter)


  • Graphic cards of any kind are NOT supported.
  • The PCIe card driver must be compatible with requirements for Thunderbolt technology.
  • This compatibility list is updated whenever a new card has been tested and verified.
  • Cards that are not listed are not necessarily incompatible, it just means that we have not tested it (yet).
  • If you own a card that is not listed above and know that it works, please let us know.
