  • Connect USB 3.0 20-pin devices to USB 2.0 motherboard headers
  • Connect USB 2.0 9-pin devices to USB 3.0 motherboard headers
  • Reversible design supports both connection directions with one adapter
  • Data transfer runs at 480Mbps for USB 3.0 devices

USB 2.0 9-pin to USB 3.0 20-pin adapter

This reversible adapter connects a USB 3.0 20-pin header device to a motherboard USB 2.0 9-pin header. It also works in the opposite direction for a USB 2.0 9-pin device on a USB 3.0 20-pin header. The pack contains two adapters. It is intended for builders who need to match mismatched front-panel and motherboard connectors.

USB 3.0 20-pin to USB 2.0 9-pin conversion

It replaces the need to replace a case or motherboard when header types differ. The jump is worth it when a chassis provides a USB 3.0 front-panel connector but the board only offers a USB 2.0 header. It also solves the reverse mismatch without rewiring. Data rate is limited to 480 Mbps.

Two adapters for dual-port or spare use

The pair comfortably handles two front-panel ports or provides a spare for a second build. Each adapter runs at USB 2.0 speed, so USB 3.0 devices operate at 480 Mbps rather than their native rate. It runs out when full USB 3.0 bandwidth is required. No active electronics are included.

Questions about this item

Will the 20-pin header fit my motherboard's USB 3.0 connector?

The adapter uses a standard USB 3.0 20-pin header female socket, so it fits the corresponding motherboard header directly.

Which way do I plug the reversible 9-pin housing onto the board?

The 9-pin housing is reversible; it can be inserted either orientation onto the USB 2.0 header without forcing it.

Does the adapter need a firmware update to keep 480Mbps speeds?

No firmware is involved; the adapter is a passive wiring bridge, so it maintains 480Mbps for USB 3.0 devices indefinitely.
