USB 3.0 19/20-Pin Internal Header Extension Cable (5Gbps) – Low Profile Male to Female Motherboard Adapter

Solve tight clearances and improve internal cable routing with a low-profile USB 3.0 motherboard header extension. This 19/20-pin male to female internal extension cable is designed for PC builds where space around the motherboard header is limited by GPUs, radiators, fans or side panels. It helps reduce strain on the header, improves cable management, and extends the internal USB 3.0 connection for front-panel ports or internal devices.

Key features:

• USB 3.0 internal header extension: 19/20-pin male to 19/20-pin female

• Low-profile male connector for improved clearance in compact builds

• Supports up to 5Gbps data transfer (USB 3.0 / USB 3.1 Gen 1, system dependent)

• Reduces stress on motherboard pins and helps prevent cable pull-out

• Ideal for extending front-panel USB 3.0 leads, internal hubs and case I/O wiring

Compatibility notes:

• Fits standard USB 3.0 19-pin motherboard headers (20-pin housing with one keyed/missing pin).

• Actual throughput depends on the motherboard header, cable length, and connected devices.
