Internal USB 3.0 to Type-C Adapter

This adapter converts a motherboard 19-pin or 20-pin internal USB 3.0 header into an external USB Type-C socket. It is designed for PC builders who want to add a front-panel or rear-access USB-C port without replacing the motherboard. The board uses a compact PCBA layout with standard header alignment.

Build Integration and Clearance

The adapter plugs directly into the existing 19-pin or 20-pin header and requires no additional power cables or driver installation. It supports USB 3.0 5Gbps data transfer and supplies up to 5V/500mA for connected devices. The small footprint keeps cable routing simple and leaves surrounding headers unobstructed.

Who This Suits and Who Should Look Elsewhere

This suits builders adding a single USB-C port to a case or bracket where the motherboard already provides an internal USB 3.0 header. It does not support USB-C Power Delivery, video output or audio functions. Buyers who need charging negotiation, DisplayPort alt-mode or multiple Type-C ports should look elsewhere.

Questions about this item

Will the 5 Gbps link saturate before the 500 mA power limit on a mechanical drive?

A mechanical drive typically draws under 500 mA, so the 5 Gbps bandwidth ceiling is reached first during sustained large-file transfers.

Does the adapter or its header connection add noticeable heat during all-day file serving?

The board draws at most 500 mA at 5 V, so heat output stays low and no active cooling is needed for continuous operation.

My motherboard only has a 19-pin internal USB 3.0 header — will this plug in directly?

Yes, the adapter fits both 19-pin and 20-pin internal USB 3.0 headers, so a 19-pin header works without an extra cable.
