USB 3.0 to 2.0 motherboard adapter

This adapter connects a motherboard USB 3.0 19-pin male header to a USB 2.0 9-pin female device connector. It enables newer boards with a 20-pin USB 3.0 interface to work with legacy front-panel devices such as optical drive panels. The pack contains four cables each measuring 15 cm in length.

19-pin male to 9-pin female header

The single specification that determines compatibility is the header pin count and gender. Your motherboard or expansion card must present a 20-pin USB 3.0 header (19 active pins) for the male connector to seat correctly. The female end accepts a standard USB 2.0 9-pin plug from the peripheral.

Sustained data transfer behaviour

Double shielding with braided copper mesh and aluminium foil reduces electromagnetic and radio interference during continuous operation. The PVC jacket remains flexible after repeated bending inside a chassis. Backward-compatible signalling maintains the 480 Mbps USB 2.0 rate without degradation over long sessions.

Questions about this item

What does the 5Gpbs figure mean when this adapter is plugged into a motherboard?

The 5Gpbs rate is the USB 3.0 maximum; because the female end is USB 2.0 9Pin, actual throughput will be limited to 480Mbps once a USB 2.0 device is connected.

Which interface standard does the 19Pin male connector follow, and what speed does it cap at?

The 19Pin male follows the USB 3.0 20Pin header specification and caps at 5Gpbs, but the adapter converts it to a USB 2.0 9Pin female limited to 480Mbps.

What clearance and header layout does the 15cm cable need to fit inside a case?

The 15cm length reaches from a motherboard USB 3.0 19Pin header to a front-panel USB 2.0 9Pin connector; the PVC jacket is flexible for tight routing.
