USB 3.0 19-Pin to USB-C Adapter
This adapter connects a motherboard USB 3.0 19-pin header to a front-panel USB-C 20-pin A-Key connector. It lets builders add a USB Type-C port to a case front panel without needing a newer motherboard. The device supports the 5 Gb/s speed of the USB 3.0 header and does not convert it to 10 Gb/s. Construction uses copper conductors inside a black housing.
Build Integration and Header Compatibility
The adapter fits any motherboard equipped with a USB 3.0 or USB 3.1 Gen 1 internal 19-pin male header. It provides a female 20-pin A-Key header for the case front-panel cable, freeing the builder from hunting for a board with native USB-C headers. No extra power or driver installation is required; the link is passive and relies on the existing header bandwidth.
Suitability and Limitations
This suits PC builders upgrading older cases or custom enclosures that include a USB-C front port but lack a matching motherboard header. It is not for users who need 10 Gb/s throughput, as the 19-pin header remains limited to 5 Gb/s. Buyers whose motherboards only offer USB 2.0 9-pin headers cannot use this adapter.

Questions about this item
Will the 19-pin header on my motherboard limit the adapter to 5 Gb/s even though the front panel is USB 3.1/3.2?
Yes, the adapter does not convert the 5 Gb/s header signal to 10 Gb/s; the front-panel Type-C port will run at USB 3.0 / 3.1 Gen 1 speeds.
Does the adapter generate noticeable heat or noise when the front-panel port is used continuously?
The passive copper construction has no active cooling and draws negligible power, so it produces no audible noise and no perceptible heat during all-day use.
What motherboard header must I already have for this adapter to work?
You need an available USB 3.0 / 3.1 Gen 1 internal 19-pin male header on the motherboard.
