Connect Internal USB 3.0 Header to USB 2.0 Header

This two-pack provides a 15 cm cable that converts a motherboard USB 3.0 19 pin female header to a USB 2.0 9 pin male connector. It allows internal USB 3.0 devices or front-panel ports to connect to older header layouts. The cables support up to 5 Gbps full-duplex data rates and are backward compatible with USB 2.0. Double shielding with braided copper mesh and aluminium foil reduces electromagnetic interference.

Verify Motherboard Header Layout

Before ordering, confirm your motherboard has an available USB 2.0 9 pin header for the male end. Check that the internal device or front-panel module you intend to connect presents a USB 3.0 19 pin female socket. Ensure the 15 cm length reaches between the header and the device inside your case. The cables are plug-and-play and require no additional drivers or power connections.

Replaces Ad-Hoc Adapters for Legacy Header

These cables replace makeshift wiring or single adapters when adding USB 3.0 front-panel ports to a board with only USB 2.0 headers. The jump is worth it when you need two reliable internal connections with proper shielding and 5 Gbps capability. They are not for builders who need to connect a USB 3.0 header to another USB 3.0 header or who require longer cable runs for full-tower chassis routing.

Questions about this item

What comes in the box and do I need anything else?

The pack includes two 15 cm cables with a 19 pin USB 3.0 female connector on one end and a 9 pin USB 2.0 male connector on the other. No extra parts are required for installation.

Which version should I pick for my motherboard header?

Choose this cable when your motherboard or PCIe card provides a 19 pin USB 3.0 header and the front-panel device or drive bay uses a 9 pin USB 2.0 header.

What does the 5 Gbps rating mean once the cable is fitted?

The link can carry up to 5 Gbps full-duplex between the 3.0 header and the connected device, though actual throughput will be limited to USB 2.0 speeds because the male end is a 9 pin 2.0 connector.
