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.
* 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.
