Dual USB 3.0 A female adapter
This Vszerda adapter converts an internal motherboard 20 or 19 pin USB 3.0 header into two external USB Type A female ports. It uses a flat type PC board assembly with copper conductors for the connection. The unit is designed for PC builders who need front panel or bracket mounted USB 3.0 ports.
Thermals noise and power
The adapter is a passive component with no active cooling, fan or power circuitry of its own. It draws no separate power and adds no audible noise to the system. Thermal output is negligible because the board only routes the existing motherboard header signals to the external ports.
Sustained load behaviour
Under continuous USB 3.0 data transfer the flat PCBA simply maintains the electrical path between the header and the two Type A sockets. Performance is limited by the motherboard header implementation and the attached devices rather than by the adapter itself. No throttling or degradation occurs because there are no active components to overheat.

Questions about this item
How do I fit the 20/19 pin header onto the motherboard and which way round does the keyed block go?
Align the missing pin on the 20/19 pin header with the blocked hole on the motherboard USB 3.0 header; the flat PCBA only seats one way, so press straight down until the plastic shroud sits flush.
Will the copper conductors or the USB 3.0 Type A ports wear out and need replacing?
The copper conductors are soldered to the flat PCBA and the Type A ports are surface mounted, so no user serviceable parts exist; the adapter is replaced as a whole if a port fails.
What limits transfer speed when I copy large files continuously through both ports?
The shared 20/19 pin header provides a single USB 3.0 channel, so sustained throughput is split between the two Type A ports and capped at the USB 3.0 signalling rate.
