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

This 15 cm cable adapter connects a USB 3.0 20-pin male header to a USB 2.0 9-pin female header on a motherboard. It allows a USB 3.0 front-panel device or internal header to interface with a legacy USB 2.0 motherboard connector. The cable uses a PVC jacket for basic insulation and durability. It is sold without a retail box.

Data speed limited to 480 Mbps

The adapter transmits data at USB 2.0 speeds of 480 Mbps even when a USB 3.0 device is attached. The physical 20-pin to 9-pin conversion does not enable SuperSpeed lanes. Builders needing full USB 3.0 throughput must connect to a native 20-pin header instead.

Fits tight header layouts

The short 15 cm length suits compact cases where the front-panel USB 3.0 header sits close to the motherboard 9-pin connector. It frees up space by avoiding long cable runs that block airflow or interfere with other components. The male 20-pin and female 9-pin ends plug directly in without extra brackets.

Questions about this item

What does the 480Mbps data speed mean for my USB 3.0 device on this cable?

The cable limits a USB 3.0 device to USB 2.0 speeds, so transfers run at up to 480Mbps instead of the faster 3.0 rate.

How does the USB 3.0 20-pin to USB 2.0 9-pin interface affect what I can connect?

It adapts a motherboard's 9-pin USB 2.0 header to accept a 20-pin USB 3.0 device connector, but the link stays at USB 2.0 performance.

Will the 15cm length and PVC jacket reach my front-panel header comfortably?

The 15cm PVC-jacketed cable is designed for short internal runs between a motherboard USB 2.0 header and a nearby front-panel USB 3.0 connector.
