Vertical Dual USB 3.0 Adapter

The Vszerda adapter adds two USB 3.0 Type A ports to a desktop by plugging into a spare 20 or 19 pin internal header on the motherboard. It is aimed at builders who need extra front-panel or internal USB connections without using a rear bracket.

Capacity and headroom

Each port runs at the USB 3.0 5 Gbps rate and remains backward compatible with USB 2.0 and 1.1 devices such as flash drives or USB-LAN adapters. The adapter only provides two ports, so systems requiring more than two additional connections will need a different solution.

Thermals noise and power

The small PCBA draws power directly from the motherboard header and has no active cooling, so it adds no audible noise. Power consumption stays within the header's standard supply limits during normal operation with typical peripherals.

Questions about this item

Will the 20-pin header fit the USB 3.0 connector on my older motherboard?

Yes, the 20-pin box header plugs directly into a standard USB 3.0 motherboard header and adds two USB 3.0 Type-A ports.

How can I confirm the adapter is delivering USB 3.0 speeds after installation?

Connect a USB 3.0 flash drive; the OS should report a 5 Gbps SuperSpeed connection and transfer rates well above USB 2.0 limits.

Does the package include mounting brackets or cables, or just the PCB?

Only the vertical dual USB 3.0 Type-A PCB with 20/19-pin header is supplied; brackets and internal cables are not included.
