Enhance the USB connectivity of a desktop computer or server by adding four external USB-A 10Gbps ports with this internal PCI Express 3.0 expansion card.

Dedicated USB Controllers

With its four independent USB controllers, this PCIe USB-C card enables each port to achieve up to 10Gbps performance, reducing bottlenecks and increasing data throughput.

USB 3.2 Gen 2 (10Gbps) Performance

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.

Charge and Sync USB Devices

This USB PCI Express card can provide up to 5V 2A (10W) per USB-A port, enabling sync and charge of portables devices. If the motherboard can't supply enough power, a built-in SATA power connector supports auxiliary power to maintain stable performance.

Compatibility

The PCIe USB card is plug-and-play in most major operating systems, including Windows, macOS, and Linux. It supports PCI Express 3.0 and x4, x8, and x16 slots. The USB expansion card ships with a pre-installed standard profile bracket.
