  • Add two USB 3.0 Type-A ports via internal 20/19-pin header
  • 5 Gbps bandwidth for fast external storage and peripherals
  • Backward compatible with USB 2.0 and 1.1 devices
  • Horizontal PCB design fits tight case layouts
  • Plugs directly into motherboard USB 3.0 header

Dual USB 3.0 Header Adapter

This adapter converts a single motherboard USB 3.0 header into two external USB Type-A ports. It suits builders adding front-panel connectivity or technicians needing extra internal USB sockets for peripherals such as flash drives or wireless dongles. The horizontal PCBA layout keeps the assembly low-profile for tight chassis spaces. Backward compatibility with USB 2.0 and USB 1.1 devices is maintained.

Straightforward Header Installation

Align the 20-pin or 19-pin connector with the motherboard's internal USB 3.0 header and press firmly until seated. No drivers or software configuration are required; the ports appear immediately in the operating system. The most common issue is misaligned pins caused by forcing the connector upside-down, which can bend header pins on the board. Verify the keying notch matches before applying pressure.

Check Motherboard Header Availability

Confirm your motherboard exposes a free internal USB 3.0 header with the standard 20-pin or 19-pin box layout before ordering. The adapter occupies one header to provide two Type-A sockets, so ensure you can spare that connection. Systems lacking an internal USB 3.0 header cannot use this adapter without an additional controller card.

Questions about this item

How do I verify the adapter is delivering 3.0 speeds after connecting it to the 20-pin header?

Plug a USB 3.0 flash drive into one of the Type-A ports and check that the operating system reports a 5 Gbps connection speed in Device Manager or System Information.

What comes in the package and do I need any extra cables or brackets to install it?

The adapter board with two USB 3.0 Type-A female ports and a 20/19-pin header is supplied; no additional cables or mounting brackets are included.

Should I choose the 19-pin or 20-pin header version for my motherboard?

This single unit fits both 19-pin and 20-pin internal USB 3.0 headers, so no separate version selection is required.
