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

This adapter cable connects a USB 3.0 20-pin male device to a USB 2.0 9-pin female motherboard header. It enables the use of internal front-panel USB 3.0 peripherals such as drive bays or card readers on boards that only provide legacy USB 2.0 headers. The connection is limited to USB 2.0 signalling rates.

Fits builds with older header layouts

The 5.5 inch black cable bridges the physical gap between a 20-pin male plug and a 9-pin female socket inside the chassis. It requires an available USB 2.0 9-pin header on the motherboard and a compatible 20-pin device. The short length keeps internal routing tidy without occupying extra drive bays or expansion slots.

Passive design draws no extra power

The adapter operates within the USB 2.0 specification at up to 480 Mbps data transfer speed. It adds no active components, so thermals and noise remain unchanged from the host header. Power delivery follows the standard USB 2.0 limits provided by the motherboard.

Questions about this item

Will the 480 Mbps limit throttle my USB 3.0 20-pin device during long transfers?

Yes, the adapter meets USB 2.0 specification so sustained throughput tops out at 480 Mbps even though the device side is a 20-pin USB 3.0 connector.

Does the 5.5 inch cable run hot or draw extra power when left connected all day?

The short 5.5 inch passive cable adds no active components, so it produces no measurable heat and draws no additional power beyond what the motherboard port already supplies.

Must my motherboard already have a free USB 2.0 9-pin header for this adapter to work?

Yes, the female 9-pin end plugs directly into a USB 2.0 9-pin motherboard header; without that header the adapter cannot be used.
