Vszerda Dual USB 3.0 A Female Adapter

This adapter connects a motherboard 20 or 19 pin internal header to two external USB 3.0 Type A ports. It suits builders adding front-panel or internal USB connections to a desktop system. The blue connectors identify the USB 3.0 interface at a glance.

Copper construction and box header slot

The copper construction provides reliable signal integrity for the high-speed link. The box header slot mates securely with the motherboard male header, while the dual female Type A ports accept standard USB plugs. Backward compatibility with USB 2.0 and 1.1 devices is maintained.

Passive design draws no extra power

As a passive PCB adapter it adds no active components to the system. Thermals and noise remain unchanged because there is no fan or circuitry generating heat. Power draw is limited to the connected USB devices themselves.

Questions about this item

Does the USB 3.0 header on this adapter run at the full 5 Gbps rate?

The adapter passes the motherboard's USB 3.0 header signal directly to two Type-A ports, so the practical ceiling is the 5 Gbps defined by the USB 3.0 specification.

What motherboard header does the 20/19-pin connector fit?

It plugs into a standard internal USB 3.0 20-pin box header; the 19-pin reference covers the keyed variant that omits one pin.

How do I install it without bending pins?

Align the keyed notch on the adapter with the missing pin on the motherboard header, press straight down until seated, then secure the Type-A bracket to the case.
