Internal USB-C front-panel adapter

This adapter connects a motherboard USB 3.0 19-pin header to a front-panel USB 3.1/3.2 Type-C 20-pin A-Key connector. It enables USB-C access on cases with a compatible front port without requiring a newer motherboard. The product is suited for PC builders adding a modern front-panel port to an existing platform.

Check your motherboard header and case port

Verify that your motherboard provides a USB 3.0 internal 19-pin male header before ordering. Confirm the front-panel connector on your case is a USB 3.1/3.2 Type-C 20-pin A-Key female header. This adapter does not convert the 5 Gb/s header bandwidth to 10 Gb/s.

Sustained throughput matches header speed

Under continuous load the link runs at the 5 Gb/s rate of the source 19-pin header rather than the 10 Gb/s potential of the Type-C connector. Thermal throttling is not a factor for this passive cable assembly. Performance remains stable for long file transfers or device charging sessions.

Questions about this item

Does the adapter include a USB 3.0 19-pin header cable or must I buy one separately?

The adapter connects a motherboard USB 3.0 19-pin header to a front-panel USB 3.1/3.2 Type-C 20-pin A-Key port; the motherboard header cable is not included and must be sourced separately.

Which front-panel header version does the 20-pin A-Key connector match?

The 20-pin A-Key female header is designed for front-panel USB 3.1/3.2 Type-C connectors that use the A-Key pinout.

Will the adapter raise a 5 Gb/s motherboard header to 10 Gb/s at the Type-C port?

No, the adapter does not convert the 5 Gb/s header bandwidth to 10 Gb/s; the Type-C port runs at the header's native 5 Gb/s speed.
