Expand the USB connectivity of a desktop computer or server by adding four external USB Type-C 10Gbps ports with this internal PCI Express 3.0 expansion card. Traditional single-controller USB cards share bandwidth across all ports. With its four independent USB controllers, this USB-C expansion card enables each port to achieve up to 10Gbps, reducing bottlenecks and increasing data throughput. The high bandwidth makes the card ideal for transferring large files, real-time editing of high-resolution photos and videos on external storage, off-loading media from mobile devices, using high-resolution video capture devices, tethered photography equipment, or high-speed USB network adapters like 10G Ethernet copper or fiber adapter. This USB PCI Express card can provide up to 5V 3A (15W) per USB-C port, enabling sync and charge of portable devices. If the motherboard can't supply enough power, a built-in SATA power connector can supply additional power to the card. The PCI Express USB card
