Frequently Asked Questions
Q: What does this USB adapter cable do?
A: This USB adapter cable allows you to connect a USB 3.0 20-pin front-panel header (found on newer PC cases) to a USB 2.0 9-pin motherboard header. This is perfect if your motherboard only has a USB 2.0 internal header but your case has a USB 3.0 connector.
Q: Will my USB 3.0 devices work at full USB 3.0 speeds with this adapter?
A: Because the adapter connects to a USB 2.0 motherboard header, the maximum data transfer speed will be limited to 480 Mbps (USB 2.0 speeds). Your USB 3.0 device will function, but it will operate at USB 2.0 bandwidth through this connection.
Q: Is this adapter compatible with all PC cases and motherboards?
A: This adapter is designed for PC cases that feature a USB 3.0 19/20-pin front-panel header and motherboards with a standard USB 2.0 9-pin internal header. Please verify your motherboard and case connector types before purchasing to ensure compatibility.
Q: Do I need to install any drivers or software?
A: No. This is a purely hardware adapter cable — simply plug the USB 3.0 20-pin male end into your case's front-panel connector and the USB 2.0 9-pin female end into your motherboard header. No drivers or software installation is needed.
