PCIe 1X to 2-Port USB3.0 Expansion Card with IDE 4Pin Power Port, 5Gbps High Speed PCI Express Riser Adapter Built-in NEC720200 Controller Chip

This PCIe 1X USB3.0 expansion riser card adopts mature NEC720200 control chip, offering two independent USB3.0 external ports with up to 5Gbps ultra-fast transmission speed for file transfer, external SSD, camera, USB docking station and other peripherals.

Different from ordinary USB expansion cards, it adds an independent IDE 4Pin Molex power supply interface. You can connect PSU Molex cables to provide extra stable power, effectively solving insufficient power issues leading to unrecognized high-power USB devices.

The card maintains full backward compatibility with USB2.0 and USB1.1 devices without extra adapters. It supports mainstream operating systems including Windows 10/11, Linux, no complicated driver installation required for most systems.

Comes with a durable full-size metal mounting bracket for secure fixation inside standard desktop chassis. Compact PCB design saves internal space and will not block adjacent PCIe slots. Perfect for desktops lacking native USB3.0 ports, office equipment upgrades and multi-peripheral workstation expansion.
