SKU CH-0ATS-5GJM7

  • TypeAll-In-One Cable
  • Connect USB 3.0 front-panel ports to USB 2.0 motherboard headers
  • 19-pin male plug fits 12 cm cable into tight cases
  • 9-pin female socket accepts standard USB 2.0 header
  • Data transfers at 480 Mbps through the adapter
  • Allows internal USB devices to connect directly to motherboard

USB 3.0 to 2.0 header adapter

This 12 cm cable converts a USB 3.0 19 pin male header into a USB 2.0 9 pin female connector. It lets builders install a USB 2.0 based motherboard into a PC cabinet equipped with front USB 3.0 ports. The adapter bridges the internal header mismatch without requiring a new motherboard or case front panel.

480 Mbps throughput ceiling

Data speed is limited to 480 Mbps when a USB 3.0 device is connected through the 2.0 header. The link runs at USB 2.0 rates, so high-bandwidth peripherals will not reach their full potential. It handles standard internal devices such as card readers or front-panel hubs comfortably. Demanding external SSD enclosures will hit the bandwidth ceiling quickly.

Compact internal routing

The short 12 cm length keeps cable clutter minimal inside tight chassis. Male 19 pin and female 9 pin housings plug directly onto motherboard headers and front-panel cables. No extra brackets or power connections are required for the conversion. Builders needing to connect a 19 pin device to a 9 pin header should note this adapter works in the opposite direction only.

Questions about this item

Will the 19-pin male connector fit my case's existing front-panel USB 3.0 header?

The adapter presents a standard USB 3.0 19-pin male header, so it plugs directly into the front-panel USB 3.0 connector your case already provides.

How can I verify the link is running at the rated 480 Mbps after I connect it?

In Windows Device Manager the attached device will enumerate as a USB 2.0 device, and transfer tests will top out at 480 Mbps, confirming the adapter is operating as designed.

Does the 12 cm cable ship alone or are extra brackets or screws included?

The package contains only the 12 cm adapter cable with a 19-pin male plug on one end and a 9-pin female socket on the other; no brackets, screws or additional cables are supplied.
