PCI-E to USB 3.2 Gen 1 Expansion Card with 4 Ports (2 USB-C + 2 USB-A), PCI Express USB 3.0 Add-On Adapter Card for Desktop PC Motherboard Internal Upgrade

This PCI Express USB expansion card inserts into the vacant PCI-E x1 slot on the desktop motherboard to expand four available external USB interfaces, including two USB Type-C ports and two traditional USB-A ports, effectively solving the problem of insufficient rear panel USB ports on old or compact motherboards.

It follows the USB 3.2 Gen 1 specification with a maximum transmission speed of 5Gbps, greatly improving the efficiency of transferring videos, backup documents and mobile hard disk data, and is backward compatible with USB 2.0 and USB 1.1 devices. The card draws power directly through the PCIe bus of the motherboard, providing sufficient and stable current for high-power USB peripherals such as portable solid-state drives and docking stations.

Equipped with a standard full-height metal baffle, it is firmly fixed on the chassis rear panel with good dustproof and anti-interference performance. No manual driver download is needed for most Windows systems after physical installation, which is an economical and practical hardware upgrade accessory for DIY assemblers, office desktops and data storage workstations.
