Internal header adapter for cramped builds

The EN-Labs U320PMF15CMLOW is a 6-inch male-to-female extension that connects a motherboard 19/20-pin USB 3.0 header to a front-panel or accessory plug. Its low-profile female connector fits beneath large graphics cards or tight SLI brackets where a standard shroud would collide.

Limited to USB 3.0 header bandwidth

The link tops out at 5 Gbps because it passes the native USB 3.0 signals through a flat ribbon cable. No protocol conversion or speed upgrade occurs; the adapter simply relocates the existing header without changing its electrical ceiling.

Push-on fit with one orientation trap

Both ends are keyed headers, so installation is a straight push onto the motherboard pins and the device plug. The only common mistake is reversing the 19/20-pin block by one row, which leaves the connector misaligned and the port dead until reseated.

Questions about this item

Should I pick the 19-pin or the 20-pin header version for my motherboard?

The adapter fits both 19-pin and 20-pin USB 3.0 headers, so either version on your board will work.

What does the 5 Gbps figure mean once the cable is installed inside my case?

It is the maximum USB 3.0 SuperSpeed data rate; real-world throughput will depend on the connected device and system load.

Which interface standard does the 19/20-pin connector use, and what does it cap in practice?

The connector follows the USB 3.0 internal header specification, limiting transfer speed to 5 Gbps.
