This internal 9-pin USB 2.0 splitter cable expands a single motherboard USB 2.0 9Pin header to four female connectors. It effectively addresses the common issue of limited internal USB ports on desktop motherboards.

The cable follows standard USB 2.0 protocol with a maximum transmission rate of 480Mbps. It works perfectly with low-power internal peripherals including chassis USB panels, lighting controllers, cooling fans and data readers.

No extra software or drivers are required. Designed for installation inside PC cases, convenient for hardware enthusiasts and system integrators.

Important Notice

This cable only supports USB 2.0 speed and cannot achieve USB 3.0 performance. Do not connect high-power USB devices; keep total load within the motherboard headers current rating to prevent hardware failure.
