Vszerda USB 2.0 9-Pin to USB 3.1/3.2 Type-C 20-Pin A-Key 180° Front Panel Adapter

SKU CH-9RMM-C3NKT

Converts a motherboard USB 2.0 9-pin header to a front-panel USB-C 20-pin A-key port with a 180-degree connector to avoid clearance issues

  • Specifications0.02 kilograms
  • Adds front-panel USB-C access to older boards via 9-pin USB 2.0 header
  • 180-degree connector avoids clearance issues with motherboard layout or chassis
  • Transfers data at USB 2.0 speeds through the 9-pin internal interface
  • Works with any motherboard USB 2.0 9-pin header on Windows or Linux
  • Plug-and-play extension requires no driver installation

Adapter purpose and audience

This adapter connects a motherboard USB 2.0 9-pin header to a front-panel USB Type-C 20-pin A-key port. It lets older boards expose a modern Type-C connector for devices that use the reversible plug. Data moves at USB 2.0 speeds. No driver installation is required on Windows or Linux.

Thermals noise and power

The unit is a passive cable assembly with no active components, so it adds no audible noise and negligible heat. Power draw is limited to what the USB 2.0 header can supply. The 180-degree connector orientation helps avoid interference with nearby motherboard headers or chassis structures.

Upgrade context and limits

It replaces a missing front-panel Type-C port on cases that only provide the newer connector while the board has legacy headers. The jump is worth it when you need the physical Type-C shape for convenience but can accept USB 2.0 transfer rates. It does not add USB 3.1 or 3.2 bandwidth.

Questions about this item

How do I install the 9-pin to 20-pin A-key adapter on my motherboard header?

Align the 9-pin plug with the USB 2.0 header, press straight in with the 180-degree connector facing away from the board, and secure the Type-C bracket to the front panel before powering on.

What maintenance or replacement will the adapter need later?

No scheduled maintenance; if the Type-C port wears loose or the header pins bend, replace the whole adapter.

What limit appears first during sustained file transfers?

The USB 2.0 header caps throughput at 2.0 speeds, so large copies hit that bottleneck immediately.
