  1. Windows requires a Thunderbolt 2 interface in the computer and in the expansion chassis to support more than two PCIe controllers. Note that some PCIe cards have a bridge to multiple controllers, so it is possible for a single dual-controller PCIe card to reach the limit if not connected via Thunderbolt 2. Not all Mac-compatible PCIe cards are also compatible with Windows. See the PCIe Card Thunderbolt Compatibility Chart for details.
