Internal USB 3.0 Expansion

The Vszerda adapter converts a single motherboard 19/20 pin header into two external USB Type A ports, adding front-panel connectivity for desktop builders who need more ports without occupying a PCIe slot. It suits system integrators and DIY enthusiasts upgrading older cases or compact chassis where internal headers remain unused.

Shielding and Signal Quality

A pure copper 2428# conductor with 6.0 mm outer diameter carries the signals, wrapped in aluminium foil and braided copper mesh plus aluminium platinum shielding to suppress electromagnetic and radio interference. The construction supports stable 5.0 Gbps transmission while maintaining backward compatibility with USB 1.1 and 2.0 peripherals.

Sustained Transfer Behaviour

Under continuous load the 25 cm cable maintains the rated 500 MB/s throughput thanks to the multi-layer shielding and low-resistance copper core, avoiding the thermal throttling or signal degradation seen in thinner unshielded alternatives. The short length further minimises voltage drop during extended large-file copies or sustained device operation.

Questions about this item

How do I install the 20-pin Y splitter cable and what step is often missed?

Connect the 20-pin plug to the motherboard USB 3.0 header, then secure the two USB Type A female brackets to a rear slot or drive bay; the step often missed is fully seating the 20-pin connector so all 19 active pins make contact.

What maintenance or replacement will the 25 cm cable need over time?

The pure copper 2428# wire with aluminum foil and braided shielding requires no scheduled maintenance; replace only if the USB Type A ports become loose or the 6.0 mm jacket shows cuts or severe kinks.

What limit appears first during sustained 5.0 Gbps transfers?

The 25 cm length and 2428# conductors keep signal loss low, so the first limit is usually the motherboard header’s 500 MB/s throughput ceiling or the attached device’s own write speed.
