Front-panel header adapter

This BUCIER adapter converts a motherboard USB 3.0 19-pin header into a USB 3.1 Type-E port for a front-panel Type-C connector. It suits builders adding a modern front-panel port to a board that only exposes the older 19-pin header. The PH73S variant uses a straight 180-degree orientation for direct bracket mounting.

Build integration notes

The adapter draws up to 4.5 W from the USB 3.0 header and does not increase the 5 Gbit/s signal rate to 10 Gbit/s. It is not compatible with a USB 2.0 IDC connector and cannot supply the power needed for tablet charging. Install only after removing the power cable and waiting briefly to avoid shorting pins.

What the bundle changes

The single black plastic-and-metal unit adds a Type-E female header without requiring a new motherboard. It enables Type-C device connection at existing USB 3.0 speeds while fitting a standard PCI bracket slot. No driver installation is needed for the supported operating systems.

Questions about this item

What is the maximum data rate the PH73S adapter can sustain when connected to a USB 3.0 19-pin header?

The adapter passes through the USB 3.0 Gen 1 signal, so the sustained rate remains at 5 Gbps and cannot be increased to 10 Gbps.

How much power can the motherboard USB 3.0 header deliver through this adapter during all-day operation?

The header is rated at 4.5 W (0.9 A at 5 V); drawing more may trigger motherboard protection and shut the port down.

Which motherboard connector must already be present for the PH73S to function?

A USB 3.0 19-pin or 20-pin front-panel header is required; the adapter will not work with a USB 2.0 IDC connector.
