PH22C USB 3.0 header adapter

The Vszerda PH22C connects a motherboard USB 3.0 19-pin or 20-pin header to two standard USB-A ports. It uses a multi-layer circuit board with integrated high-speed signal optimisation for lossless transmission. The adapter adds front-panel USB 3.0 connectivity to a desktop chassis.

Builders adding front USB 3.0 ports

This adapter suits anyone fitting two USB-A sockets to a case front panel where the board header is 19-pin or 20-pin. It includes two 3 mm mounting holes for DIY securing. Systems without a spare USB 3.0 header, or builds needing Type-C front ports, cannot use this part.

19/20-pin header to dual USB-A

The single specification that decides fit is the header pin count: the PH22C accepts a 19-pin or 20-pin USB 3.0 motherboard header and breaks it out to two female USB-A connectors. No other interface or pin arrangement is supported.

Questions about this item

Does my motherboard need a 19-pin or 20-pin USB 3.0 header to use this PH22C adapter?

The PH22C plugs into a standard USB 3.0 19-pin or 20-pin motherboard header and provides two USB-A female ports for front-panel use.

Will this adapter run at USB 3.0 speeds if I connect older USB 2.0 devices to its ports?

Yes, the adapter carries USB 3.0 high-speed signals and is backward compatible, so USB 2.0 devices will work at their normal rate.

How can I confirm the PH22C is delivering USB 3.0 performance after I install it?

Plug a USB 3.0 flash drive into either port and check that the operating system reports a SuperSpeed connection and shows transfer rates consistent with USB 3.0.
