Dual 19-pin motherboard adapter

This Vszerda adapter converts a single 19-pin motherboard header into two USB 3.0 Type-A female ports. The flat-profile design fits internal headers without occupying PCIe or PCI expansion slots. Each pack contains two adapters, giving builders a straightforward way to add front-panel or internal USB 3.0 connectivity. No driver installation is required for plug-and-play operation.

Thermals noise and power draw

The fully moulded metal-and-PVC construction provides stable signal transmission with strong anti-interference shielding during normal use. Passive operation means no fan noise and no additional power draw beyond what the motherboard header supplies. Backward compatibility with USB 1.1 and 2.0 devices ensures legacy peripherals function without extra configuration. The compact 9.9 by 15.7 by .5 cm form factor keeps cable routing tidy inside the chassis.

Sustained load behaviour

Rated at 5 Gbps, the adapter maintains SuperSpeed USB 3.0 throughput during extended file transfers or continuous device operation. The 20-hole connector leaves one pin unused, matching the 19-pin header specification for reliable contact over long sessions. Each unit weighs 36 g, adding minimal stress to the motherboard header during prolonged use. Builders who need more than two additional ports or a right-angle form factor will require a different solution.

Questions about this item

How do I install the 19-pin flat adapter onto the motherboard header, and which hole do I leave empty?

Align the 19-pin plug with the motherboard's 19/20-pin header; the connector has 20 holes but only 19 pins, so one hole remains unused — match the keyed notch to avoid bending pins.

Will the metal shielding or PVC housing need any upkeep or replacement over time?

The fully moulded metal-and-PVC construction has no moving parts or serviceable components, so no scheduled maintenance or replacement is required under normal use.

What sustained throughput limit appears first when both USB 3.0 ports are transferring data simultaneously?

The shared 19-pin header caps aggregate bandwidth at the USB 3.0 5 Gbps signalling rate, so combined transfers cannot exceed that ceiling.
