USB 2.0 9-pin header splitter for internal power

This adapter converts a single motherboard USB 2.0 9-pin female header into two male 9-pin ports. It suits builders who need extra internal connections for devices such as fan controllers or LED lighting strips. The 2.54 mm pitch matches standard motherboard headers. Two cables are included in the pack.

Sustained-load behaviour with shared bandwidth

Only one of the two ports can transmit data at any moment; the other remains power-only. Under continuous use the splitter therefore delivers full USB 2.0 throughput to a single device while the second port supplies up to 10 watts of power. This arrangement prevents bus contention during long transfers.

Practical limits of the USB 2.0 header interface

The motherboard header must support multiple logical ports on a single physical connector; some older boards do not. The cable is wired differently from certain vendor-specific splitters, so compatibility should be verified. It is intended for internal USB 2.0 power and data only, not for external or higher-speed standards.

Questions about this item

Does the USB 2.0 9-pin splitter draw extra power when running fans or LED lights all day?

The splitter only passes power from the motherboard header; it adds no extra draw itself. Each connected fan or LED light uses the header's existing 5 V supply.

What motherboard header is required for this 9-pin female to dual 9-pin male cable to work?

You need a spare internal USB 2.0 9-pin header with 2.54 mm pitch on the motherboard. The female end plugs directly into that header.

Can I keep my older Corsair iCUE pump and a USB wireless receiver on the same header using this splitter?

Yes, the cable splits one header into two 9-pin males. One port can power the pump while the other handles data for the receiver, provided the board supports multiple connections per header.
