Motherboard USB3.0 19Pin 20Pin 1to2 Expansion Cable 12CM, Internal Mainboard USB 3.0 20Pin Header Splitter Cord, 19Pin 1 to 2 Power Extension Wire for PC Case FrontPanel USB Port Expansion

This 12CM motherboard USB3.0 19Pin 20Pin 1to2 internal expansion splitter cable is designed to solve insufficient onboard USB 3.0 header issues on your mainboard. It takes a single standard USB3.0 19Pin / 20Pin internal header from motherboard and splits it into two identical output headers, allowing you to connect two sets of frontpanel USB3.0 ports using only one motherboard socket, great for custom PC builds and chassis upgrades.

Constructed with premium tinned multistrand copper conductors, the cable supports full USB3.0 highspeed data transfer while maintaining stable power supply, reducing signal attenuation and interference inside the crowded computer case. Both ends adopt highprecision injectionmolded connectors with locking buckles, which clip tightly onto motherboard headers to avoid accidental disconnection, intermittent signals or unstable power caused by loose plugs during installation or case movement.

At only 12 centimeters in length, this shortform cable avoids redundant slack wires, keeps internal chassis wiring tidy and improves airflow for better heat dissipation. The flexible insulated outer layer resists bending, abrasion and aging for longterm service life. Fully plugandplay, no additional drivers or software installation required. Suitable for desktop DIY assembly, aftermarket case modification, home PC upgrade and hardware debugging. Important reminder: Please verify your motherboard header specification before purchase; do not exceed the rated current load to maintain normal function.
