This horizontal USB 3.0 header splitter is specially designed for motherboards with standard 19/20 pin internal USB3.0 connectors. It converts one original motherboard USB3.0 header into two independent USB 3.0 ports, effectively solving the insufficient front panel USB interface problem for your PC case.

Adopting horizontal flat structural design, it avoids space occupation conflicts with surrounding capacitors, cables and cooling radiators inside the chassis, making internal wiring neater and installation easier. It maintains standard USB 3.0 5Gbps transmission speed, ensuring smooth and stable transmission of large files without signal attenuation or delay.

Plug and play without extra driver installation, fully compatible with all mainstream desktop motherboards equipped with 19/20Pin USB3.0 headers. Suitable for connecting front panel USB ports, internal card readers, RGB lighting accessories and other internal USB peripherals, an essential accessory for DIY PC assembly and chassis interface expansion.
