  • Single-port Super-Speed USB3.1 PCI Express Card
  • Supports USB data transfer rate of 10G/5G/480/12/1.5 Mbps
  • Driver supports for Microsoft Windows 7, 8.x and 10 operation systems

Super-Speed plus USB3.1 Type-C is the next revolution in I/O interconnect standards that will deliver the bandwidth and features required by PCs, consumer electronics and portable devices. With better performance, small form factor, high power capacity feature, Super-Speed plus USB3.1 Type-C interface will be the trendy of IT technology.

SUNIX USB2311C is a single-port Super-Speed USB3.1 PCI Express card, and it's compliant with the PCI Express Generation 3 specification for host PC system. Based on USB Type-C pure DFP (Downstream Facing Port) mode, it works up to 10 Gbps for data transfer when connecting to USB 3.1 compliant peripherals, while maintaining compatibility with existing USB peripheral devices. USB3.1 performance is 2 times faster than USB3.0 and 20 times faster than USB2.0 connectivity.

With USB Type-C Receptacle, SUNIX USB2311C sports reversible plug orientation and cable direction, which means that users will no longer need to be concerned with plug orientation/cable direction, making it easier to plug in. The new connector is smaller and thinner design, but drive higher power output capacity to USB device. SUNIX USB2311C supports 5VDC@3000mA power output to USB device with over current protection on each USB port. This card is an ideal choice for external storage devices, digital cameras, webcam, video devices, and all other USB electronic devices.
