PCIe 1X Expansion Card with 4 Ports USB 3.0 + USB Type-C Port, 5Gbps High Speed PCI Express USB Hub Controller Card, Low Profile Bracket Included for 2U Rack Server Chassis and Standard Desktop Comput

This PCIe X1 internal USB expansion card is a practical port upgrading solution for desktop PCs and 2U rack-mounted server chassis with limited rear panel interfaces. It is designed to be inserted into the free PCI Express 1X slot on the motherboard to expand multiple high-speed external USB ports, effectively solving the problem of insufficient onboard USB sockets when connecting USB flash drives, external hard disks, card readers, cameras, docking stations and other peripherals.

The card integrates four USB 3.0 Type-A interfaces and one reversible USB-C port, all running under USB 3.0 protocol with maximum 5Gbps data bandwidth, which greatly accelerates the transmission of large-capacity files, raw video footage and backup archives, and is backward compatible with USB 2.0 and USB 1.1 legacy devices for broader applicability.

The biggest highlight is the matched low-profile half-height baffle. After replacing the standard full-height metal bracket, the card can be perfectly installed inside compact 2U rack server cabinets without structural interference, meeting the installation dimensional requirements of industrial servers, network storage devices and small chassis workstations.

The internal intelligent controller chip optimizes data processing efficiency, reduces system CPU resource consumption under multi-port simultaneous load, and runs with low heat generation to support 24-hour uninterrupted stable work. The gold-plated port contacts resist oxidation and poor contact caused by frequent plugging and unplugging, extending the service life of the expansion card.

Installation steps are simple and intuitive: power off the host, insert the card into the PCIe X1 slot, fix the bracket with screws, then install the official driver for automatic identification. It supports all mainstream Windows desktop systems, Windows Server versions and various Linux distributions.

It is widely used for DIY desktop port expansion, 2U server peripheral expansion, industrial control host equipment connection and studio multi-device wiring management, a cost-effective internal USB expansion hardware for IT administrators and PC assemblers.
