4 Independent Port PCI Express PCIe SuperSpeed USB 3.0 Controller Card Adapter with SATA Power - Low Profile

The PEXUSB3S400 PCI Express USB 3.0 Card adds 4 independent external USB 3.0 ports to any PCI Express x4-enabled computer system, with full bandwidth support (up to 5Gbps) per port when connected to USB 3.0 devices.Unlike other USB 3.0 cards, which share the maximum bandwidth between multiple ports, the PEXUSB3S400 offers maximum transfer rates to each device when multiple devices are connected.

This 4-port USB 3.0 card features a stacked port layout, which places the ports one on top of the other, so more ports are able to fit into a smaller space. Plus, with a built-in SATA power connector, each USB port can provide up to 900mA of power to devices that draw power from a host bus connection (500mA for USB 2.0) by connecting to your computer power supply.

The PEXUSB3S400 USB 3.0 PCIe x4 card is backed by a StarTech.com 2-year warranty and free lifetime technical support.
