This PCI Express USB 3.0 expansion card adds two extra USB3.0 ports to desktops lacking sufficient external interfaces, supporting up to 5Gbps file transfer speed for flash drives, external hard disks, cameras and other USB peripherals.

The onboard SATA power supply interface solves insufficient power output issues of motherboard PCI-E slots, stably driving high-power USB devices without disconnection or slow charging. Optimized PCB wiring reduces signal attenuation, and gold-plated USB contacts resist oxidation for durable use.

Comes with universal full-height metal backplate for secure mounting inside computer cases. No extra complicated firmware needed; install basic drivers after plugging into PCI-E slot to work normally. Ideal for office PC upgrades, design workstations and multi-peripheral desktop setups.
