This Addonics USB 3.1 type-C PCIe controller is a simple and economical solution for adding the latest high speed 10 Gbps USB 3.1 type C port to any Desktop computers or servers. Designed to install into any PCI-Express 4X slot, the USB 3.1 port on this controller can handle data rate up to 10 Gbps on the PCIe 2.0, doubling the speed of USB 3.0.


  • Add two USB 3.1 type C portsvia PCI-Express (PCIe) 4-lane slot
  • Maximum 10 Gbits/sec*, twice the speed of USB 3.0 and 20 times the speed of USB 2.0
  • Supports both PCIe 1.0, 2.0 or 3.0
  • Includes both standard height and low-profile brackets
  • Power directly from PCI-Expressd slot or via 15-pin SATA power connector
    (SATA power connection is required for providing more than 500 mA BUS power)
  • Hot swappable - drive can be removed and added without system shut down or restart
  • Capable ofSuperSpeed (10Gbps, 5Gbps), HighSpeed (480 Mbps), FullSpeed (12 Mbps), and LowSpeed (1.5 Mbps) transaction
  • Compatible with Windows 7, 8.1 10 and Windows server

*To achieve the maximum throughput, the PCI-Express slot must be version 2.0 or higher. Older Notebook with PCI-Express 1.0 will limit the speed to 5 Gbps. Performance per port may decrease if both ports are transferring data simultaneously due to the limited throughput of the PCI-Express slot.
