Mini USB 19 Pin / 20 Pin Internal Header 1 to 2 Splitter Extension Cable, Motherboard USB3.0 Internal Port Adapter Cord for Desktop PC Front Panel Connection Expansion

This mini internal USB splitter cable is specially designed for motherboard USB 3.0 19Pin/20Pin internal headers. It can split a single motherboard USB3.0 header into two interfaces, solving the problem of insufficient built-in USB ports on your mainboard.

The adapter cable supports standard USB3.0 internal front panel connections and works with most mainstream desktop motherboards equipped with 19Pin or 20Pin USB headers. Compact wire layout helps organize cables neatly inside narrow computer cases without blocking airflow.

Precision-molded connectors provide secure plug-in connection to prevent loose contact, signal drop-out or intermittent disconnection during long-term operation. It supports full USB3.0 data transmission speed for front USB panels, card readers and other internal peripherals.

Perfect for custom PC assembly, chassis modification, hardware upgrades and connecting multiple front-panel USB devices.

Important Reminder: Total power output is shared between two split ports. Avoid connecting multiple high-power USB devices simultaneously. Please confirm your motherboard header definition matches before installation to prevent abnormal recognition.
