Internal header extender for USB 3.0

The Micro SATA Cables LP-1156-U3 extends a 20-pin internal USB 3.0 header from the motherboard. Its low-profile connector suits tight layouts such as multi-GPU builds where expansion cards block direct access. The male-to-female design adds reach without changing the pinout. Builders who need internal front-panel USB 3.0 ports in cramped cases will find it useful.

Fits between motherboard header

The extender plugs into the existing 20-pin header and accepts the case’s front-panel USB 3.0 lead. No additional power connection or driver is required; the link is passive. It frees routing space behind large graphics cards or thick cable bundles. Builders who need to convert the header to a different external connector type cannot use this cable alone.

Passive cable with minimal thermal impact

The assembly draws no power of its own and adds negligible resistance to the USB 3.0 signal path. No active cooling or fan header is involved, so system thermals and acoustic profile remain unchanged. The short 8-inch length keeps voltage drop well within specification for normal peripheral loads. Users who require active signal boosting for longer runs will need a different solution.

Questions about this item

Will the 20-pin header extender reach across an SLI setup without signal loss at USB 3.0 speeds?

The cable is approximately 8 inches long and designed for low-profile motherboard headers, making it suitable for tight SLI configurations while maintaining USB 3.0 performance.

Does the low-profile connector add noticeable heat or electrical resistance when the header runs continuously?

The passive extender uses a direct pin-to-pin layout with no active components, so it does not generate additional heat or measurable resistance during all-day operation.

What motherboard header type must already be present for this LP-1156-U3 cable to function?

Your motherboard must provide a standard 20-pin internal USB 3.0 header; the cable extends that existing connection without converting or adapting other interfaces.
