Frequently Asked Questions

Q: Is this USB 3.0 19-pin splitter cable compatible with my motherboard?

A: Yes — this cable is compatible with virtually any motherboard that has a standard USB 3.0 internal header (19-pin or 20-pin). The 20-pin connector simply has one pin position left empty, which is also referred to as a 19-pin configuration. Check your motherboard manual to confirm you have a USB 3.0 internal header.

Q: Can I use both USB 3.0 outputs at the same time?

A: Both female USB 3.0 Type-A connectors are active simultaneously, but the total bandwidth is shared from the single motherboard header. For typical USB 3.0 device usage (flash drives, card readers, etc.), both ports will function normally side by side.

Q: How do I mount the USB 3.0 female connectors to my PC case?

A: Each USB 3.0 Type-A female connector includes screw-mount holes, allowing you to fasten them securely to a case bracket, I/O panel, or any custom cut-out with standard screws. This makes for a clean, professional installation.

Q: What is the cable length, and will it reach inside my case?

A: The cable is approximately 12 cm (4.72 inches) long. This is designed for internal routing close to the motherboard header. For most mid-tower and full-tower cases, it comfortably reaches nearby panel brackets. If you need a longer run, consider using a USB 3.0 internal extension cable in addition.
