Internal front-panel USB 3.0 adapter

This HANNORD cable converts a single motherboard 20-pin USB 3.0 header into two external Type-A ports for a PC front panel or bracket. It is intended for system builders adding front-panel connectivity to a compatible board. The 30 cm length suits compact chassis routing. Buyers needing more than two ports should look elsewhere.

Black Y-split cable with 19-pin plug

The assembly uses a black cable with a 19-pin connector that fits the 20-hole header; one hole remains unused. Two female Type-A sockets mount in a standard expansion slot or front-panel cut-out. Backwards compatibility with USB 2.0 devices is supported. No PCI bracket is included, so a separate bracket or case opening is required.

Check header keying and clearance before ordering

Verify the motherboard provides a standard USB 3.0 20-pin header with the correct keying for the 19-pin plug. Ensure the 30 cm reach spans from header to the chosen mounting location without tension. Confirm the case or bracket has space for two Type-A cut-outs.

Questions about this item

What USB standard does the 20-pin header connection support, and what is its maximum data rate?

The cable connects a motherboard USB 3.0 20-pin header to two USB 3.0 Type-A female ports, providing SuperSpeed USB 3.0 data rates up to 5 Gbps and backward compatibility with USB 2.0 devices.

What physical space and mounting does the cable require for installation in a PC case?

The 30 cm Y-splitter cable fits a standard rear PCI bracket slot; the two USB 3.0 Type-A female connectors mount in that slot while the single 20-pin header plug reaches the motherboard connector.

How is the cable installed, and which step is commonly missed?

Power off the PC, align the 20-pin header plug with the motherboard USB 3.0 header (one hole remains unused because the plug has 19 active pins), press firmly until seated, then secure the bracket-mounted female ports to the case slot.
