Adapter for legacy USB panels

This adapter cable bridges a USB 2.0 9-pin male connector to a USB 3.0 20-pin female header on the motherboard. It allows front-panel drive bays, floppy-style panels or similar 9-pin devices to plug into newer 20-pin headers. The four-inch length keeps routing tidy inside compact cases. Builders updating older peripherals on modern boards will find it useful.

Speed limited to USB 2.0 rates

Although the motherboard side uses a 20-pin USB 3.0 header, the link operates at 480 Mbps because the device end is a 9-pin USB 2.0 interface. The extra pins on the 20-pin side carry SuperSpeed lanes that this adapter cannot utilise. Any connected peripheral will therefore run at High-Speed USB 2.0 throughput only. Do not expect 5 Gbps performance from this connection.

Nine-pin device compatibility required

The adapter only works when the peripheral presents a standard USB 2.0 9-pin male header. Panels or cables with 10-pin, 19-pin or proprietary layouts will not mate with the 9-pin male end. Verify the device connector pin count before purchase; this cable cannot adapt other header types.

Questions about this item

Should I choose the 9-pin or 10-pin version for my drive panel?

The adapter has a 9-pin USB 2.0 male connector; it fits 9-pin drive panels and floppy panels.

What does the 480 Mbps rating mean when I plug a USB 3.0 device into this adapter?

The link runs at USB 2.0 speed, so any USB 3.0 device connected through it is limited to 480 Mbps.

Does the 20-pin motherboard header carry USB 3.0 signals through this cable?

The 20-pin female end plugs into a USB 3.0 header, but only the USB 2.0 pins are wired, capping the connection at 480 Mbps.
