  • Works with ASUS ROG Maximus IX Formula and Strix Z270 boards

USB 3.1 Front Panel Extension

This 30 cm cable connects a USB 3.1 front panel header to a USB 3.0 20 pin header on ASUS motherboards. It is built for builders adding or relocating front panel USB ports. The connector uses a Lighting Connector to USB A interface. It supports USB 3.1 and 3.0 devices only.

Upgrading From USB 3.0 Header

The cable bridges the newer USB 3.1 header pinout to the existing USB 3.0 20 pin header found on boards like the Z270 series. It is worth the jump when a case provides a USB 3.1 front port but the motherboard lacks the matching header. It cannot work with USB 2.0 480 Mbps connections.

Sustained Data Transfer Behaviour

The extension maintains the USB 3.1 pin set and backwards compatibility during sustained file transfers. It handles the increased pin count required by the USB 3.1 interface without signal degradation over the 30 cm length. The cable is designed for continuous operation at 3.1 and 3.0 speeds.

Questions about this item

Does the 30 cm cable reach from the ASUS ROG MAXIMUS IX FORMULA USB 3.1 header to a front-panel USB 3.0 20-pin header?

The 30 cm length connects a motherboard USB 3.1 front-panel header to a case USB 3.0 20-pin header on compatible ASUS boards such as the ROG MAXIMUS IX FORMULA and STRIX Z270I/Z270G.

Which way round do the USB 3.1 and USB 3.0 20-pin connectors go, and what is the common mistake?

Plug the USB 3.1 header end into the motherboard and the USB 3.0 20-pin end into the case front panel; reversing them prevents the cable from working because the pin-outs differ.

Will the cable still function if I later add a USB 2.0 front-panel device?

No, the cable only supports USB 3.1 and USB 3.0 devices and cannot operate at USB 2.0 480 Mbps speeds.
