9 Pin to 11 Pin USB Header Cable

This 12cm adapter cable connects Lenovo motherboards with proprietary 11-pin mini USB headers to standard ATX chassis front-panel USB ports. It is intended for system builders and upgraders who need to reuse a Lenovo board inside a regular case. The plug-and-play design requires no drivers or configuration.

Replaces proprietary front-panel wiring

The cable replaces the need for a custom Lenovo front-panel assembly or a case-specific header. The jump is worthwhile when moving a Lenovo M540, M720T, M920T or M930T motherboard into an aftermarket chassis that only provides a standard 9-pin USB connector. Without this adapter the front USB ports remain unusable.

Handles standard front-panel USB signals

The 24AWG tinned copper conductors carry both data and power for two USB 2.0 ports with stable conductivity. The 12cm flat ribbon layout fits tight routing paths and reduces internal clutter. It does not support internal headers that use a different pin count or pitch, nor does it add extra USB ports beyond what the motherboard header provides.

Questions about this item

What motherboard header pitch and pin count does the 11-pin female connector match?

The 11-pin female end fits Lenovo proprietary mini USB headers with a 2.0mm pitch, used on models such as M540, M720T, M920T and M930T.

Which orientation do the keyed notches on the 9-pin male and 11-pin female connectors require during installation?

Align the missing-pin key on the 9-pin male plug with the chassis header notch, and the 11-pin female socket key with the motherboard header notch; forcing either connector reversed bends pins.

When should the 12cm flat ribbon cable be replaced if front-panel USB ports become intermittent?

Replace the cable if the 24AWG tinned copper conductors show cracked PVC insulation, crushed flat ribbon sections, or corroded pins after repeated case opening.
