This PCI Express USB 3.0 expansion card adds two extra USB 3.0 interfaces to your desktop PC that lacks enough external ports, supporting 5Gbps bandwidth to speed up copying large files to USB flash drives, external HDDs and cameras.

The additional SATA power connector fixes the insufficient power supply problem of native PCI-E slots, preventing disconnection, slow charging or recognition failure of high-power USB devices. Gold-plated USB ports resist oxidation and poor contact after frequent plugging.

Equipped with a universal full-height metal backplate for firm installation inside the chassis. Just insert it into the motherboard PCI-E slot and install basic drivers to get fully functional USB 3.0 ports. Great for office PC upgrades, design workstations and multi-peripheral desktop setups.
