The PEXUSB3S4V PCI Express USB 3.0 Card (with SATA Power) adds 4 external USB 3.0 ports to any PCI Express-enabled computer system. SuperSpeed USB 3.0 provides up to 5 Gbps of data bandwidth, while remaining backward compatible with existing USB 2.0 devices at 480Mbps.
Using a "stacked" port layout that places the ports one on top of the other, more ports are able to fit into a smaller space. This 4-port PCIe USB 3.0 adapter enables all four USB 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low profile computer system.
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 PEXUSB3S4V USB 3.0 PCIe card is backed by a StarTech.com 2-year warranty and free lifetime technical support.
