Dual Profile PCI Express 4-Port SuperSpeed USB 3.0 Host Adapter


SIIG’s DP USB 3.0 4-Port PCIe i/e is a high performance adapter card designed to instantly add four additional USB 3.0 ports (1 internal and 3 external) to your PCIe-enabled desktop computer. Its USB 3.0 interface delivers ultra-fast USB 3.0 data transfer rate of up to 5Gb/s, and allows you to hot-swap devices (connect and disconnect) without first turning your system off. It supports per port over-current protection to protect connected devices and the board itself from unforeseen power surges, offers backward compatibility for USB 2.0 and USB 1.1 devices and supports the simultaneous operation of USB 3.0, USB 2.0 and USB 1.1 devices. This dual profile USB 3.0 4-Port PCIe host adapter works with a wide variety of high-bandwidth USB 3.0 devices, including USB 3.0 hard disk drive enclosures, high-resolution webcams, video surveillance cameras, digital video cameras, and multi-channel audio devices. The dual-profile PCB design along with the included spare low profile bracket allows this USB 3.0 adapter to be installed in either standard height or low profile systems providing the utmost flexibility in system chassis installation.
