USB 3.0 header splitter for motherboards

This cable turns a single 19/20 pin USB 3.0 header on the motherboard into two female headers using a 1 to 2 Y splitter design. It is intended for builders who need to connect multiple front-panel USB 3.0 ports or internal devices when only one header is available.

Dual headers and flat ribbon construction

The 30cm flat ribbon cable provides two female 19/20 pin connectors from one male plug, allowing simultaneous bi-directional data transfer at up to 5Gbps. The ribbon layout is more durable and flexible than individual crimped wires and helps keep the internal wiring tidy.

Motherboard header fit and iCUE 7000X exclusion

The male connector that plugs into the motherboard may feel loose on some boards because header dimensions vary between manufacturers. The supplier also notes that this cable is not compatible with the Corsair iCUE 7000X case, so builders using that chassis should choose a different solution.

Questions about this item

Will the 19/20 pin male connectors need replacement after repeated case changes?

The flat ribbon construction resists fatigue better than individual crimped wires, so the male ends should survive multiple builds without degradation.

What limits throughput first when both female ports run sustained transfers?

The single 5 Gbps upstream link from the motherboard header is shared, so combined traffic cannot exceed that ceiling.

Does the 30 cm ribbon add noticeable heat or fan noise inside the chassis?

Passive copper ribbon carries no active components, so it generates no extra heat and requires no additional airflow.
