USB 3.0 Motherboard Header Extension Cable 19P 20Pin Adapter
USB 3.0 Motherboard Header Extension Adapter Cable — 19P/20Pin
Struggling to reach your motherboard's USB 3.0 header because your graphics card is in the way? The ATUOTIN USB 3.0 Motherboard Adapter Cable is the perfect fix. This compact 15 cm (5.9 in) flat extension cable routes your motherboard's internal USB 3.0 signal to the front-panel header on your chassis — cleanly, quickly, and without the hassle of awkward cable routing.
Key Features
- Solves Graphics Card Clearance Issues: Extends your motherboard's USB 3.0 header when a large GPU blocks direct access, giving you full front-panel USB functionality.
- 19P/20Pin Compatibility: Fits the standard 19-pin and 20-pin USB 3.0 internal headers found on the vast majority of modern motherboards.
- Female-to-Male Design: One end features a USB 3.0 female port (connects to the chassis front-panel cable); the other end is a USB 3.0 male header (plugs into the motherboard).
- Flat Black Cable: Low-profile, flat 26 AWG all-copper wire keeps your build tidy and allows for greater bending flexibility than standard chassis cables.
- Broad Motherboard Compatibility: Works with most ATX, Micro-ATX, and Mini-ITX motherboards that feature a standard USB 3.0 internal header.
- Easy Installation: Simple plug-and-play connection — no tools required beyond basic cable management.

Q: What does this USB 3.0 motherboard header extension cable do?
A: This adapter cable extends the internal USB 3.0 header on your motherboard, routing the signal to the front-panel USB 3.0 port on your PC chassis. It is especially useful when a large graphics card physically blocks direct access to the motherboard's USB 3.0 header.
Q: Is this USB 3.0 header cable compatible with my motherboard?
A: The cable is designed for standard 19-pin and 20-pin USB 3.0 internal headers, which are found on most ATX, Micro-ATX, and Mini-ITX motherboards. Please confirm your motherboard's header type (19P or 20P) before purchase to ensure compatibility.
Q: How long is the USB 3.0 motherboard adapter extension cable?
A: The cable measures 15 cm (approximately 5.9 inches) in length. This is sufficient to route around a GPU or other obstructions inside a standard mid-tower PC case while maintaining a clean build.
Q: What wire gauge is used in this adapter cable?
A: The cable uses 26 AWG all-copper wire, which ensures reliable signal transmission and maintains USB 3.0 data transfer speeds across the extension without significant signal loss.
