Internal USB 3.0 expansion cable

This 30 cm cable connects a motherboard 20-pin header to two USB 3.0 Type-A female ports. It adds front-panel or internal USB connectivity without occupying a PCIe slot. The copper conductor and shielding support reliable data transfer. Builders adding ports to a compatible header will find it a direct fit.

Header and clearance check

Verify that the motherboard provides a standard 20-pin USB 3.0 header before ordering. Measure the routing path to ensure the 30 cm length reaches the intended port location without strain. Confirm the chassis has space for two Type-A cutouts or brackets. The cable is not suited for builds lacking a 20-pin header or requiring longer runs.

Sustained transfer behaviour

Shielded copper conductors maintain signal integrity during extended file moves or device streaming. The short 30 cm run limits voltage drop under continuous USB 3.0 loads. Heat buildup stays minimal because the cable carries only data and bus power. Installations needing longer sustained runs should consider active extension options.

Questions about this item

What comes in the package and do I need any extra parts to connect it?

The package includes the USB 3.0 to motherboard cable with a 20-pin header and two USB 3.0 Type-A female ports. No additional parts are required for a standard internal connection.

The listing mentions 30 cm and 26.5 cm — which length should I plan for?

The end-to-end length is 30 cm (1 ft). The 26.5 cm (0.87 ft) figure refers to the same cable measured differently; use 30 cm for clearance planning.

Will this cable deliver full USB 3.0 speed when plugged into a 20-pin header?

Yes. The copper conductor and shielding support the USB 3.0 specification across the 30 cm run, so connected devices can operate at the rated 5 Gbps throughput.
