50cm Motherboard 20Pin to Dual Stackable USB 3.0 Female Header Cable, Internal Front Panel USB Extension Cord for PC Case Front I/O Port Expansion

This internal USB 3.0 extension cable is 50 centimeters long, designed to connect the motherboards internal 20Pin USB 3.0 header to the computer case front panel. It features a dual stackable female port layout that expands one motherboard header into two independent USB 3.0 interfaces, doubling front-panel USB availability for flash drives, external SSDs, cameras and other peripherals.

Built to official USB 3.0 specifications, the cord maintains full 5Gbps high-bandwidth transmission without speed attenuation, ideal for large file copying and high-speed external storage access. The 50cm wire length eliminates insufficient cable issues in large chassis while avoiding tangled excess wiring inside the case.

All metal contact pins are securely crimped with strain relief to resist vibration and repeated plugging, preventing signal dropouts or unrecognized devices. Compatible with all ATX, MATX and ITX motherboards equipped with standard 20Pin internal USB3.0 headers, it is an essential accessory for PC assembly, front I/O port upgrade and custom gaming chassis modification.
