  • Connect USB 3.0 20-pin devices to USB 2.0 9/10-pin motherboard headers
  • Connect USB 2.0 9/10-pin devices to USB 3.0 19/20-pin motherboard headers
  • Reversible 9-pin housing adapter simplifies front-panel installation
  • Supports 480 Mbps data transfer for connected USB 3.0 devices
  • Two-adapter pack covers both upgrade and legacy scenarios

Two-Adapter Kit for USB Header Conversion

This kit contains two adapters that bridge USB 3.0 20-pin and USB 2.0 9/10-pin headers on a motherboard. One adapter lets a USB 3.0 front-panel device connect to a USB 2.0 header, while the other lets a USB 2.0 device connect to a USB 3.0 header. Both connectors are black and weigh 0.05 kg in total.

Sustained Data Rate Limited to USB 2.0 Speed

When a USB 3.0 device is plugged into a USB 2.0 header via the included adapter, the link runs at 480 Mbps. The throughput stays at that rate for the duration of the transfer because the motherboard header itself is the bottleneck. No higher signalling rate is possible through this connection.

Check Your Front-Panel Pin Layout Before Buying

Verify that your case or device uses a standard 19/20-pin USB 3.0 header or a 9/10-pin USB 2.0 header. The adapters are designed for those specific pin counts and will not fit proprietary or differently keyed connectors. Ensure the motherboard header gender matches the adapter ends you intend to use.

Questions about this item

Does the adapter draw extra power or generate heat when running continuously?

The adapter is a passive header converter with no active circuitry, so it adds no measurable power draw or heat during all-day use.

What motherboard headers must I already have for these adapters to work?

You need either a USB 2.0 9- or 10-pin front-panel header or a USB 3.0 19- or 20-pin motherboard header, matching the device you want to connect.

Will a USB 3.0 front-panel device plugged through this adapter run at USB 2.0 speeds on my older motherboard?

Yes, the supplier rates the data speed at 480 Mbps when a USB 3.0 20-pin device is connected to a USB 2.0 motherboard header.
