Vszerda USB 3.0 19/20Pin to 2× USB A Male-Female Adapter PH22

SKU CH-B8SQ-ZBB5J

Adds two USB 3.0 Type-A ports to a motherboard 19/20-pin header with lossless high-speed transmission

  • Adds two front-panel USB 3.0 ports via a 19/20-pin header
  • Multi-layer PCB optimises high-speed signal integrity
  • Supports lossless USB 3.0 data transmission rates
  • Two 3 mm mounting holes simplify custom chassis builds
  • Works in left or right orientation for flexible routing

USB 3.0 front-panel adapter

This adapter converts a motherboard 19 or 20-pin USB 3.0 header into two standard USB Type-A ports for a chassis front panel. It is intended for PC builders adding front USB 3.0 connectivity to a desktop case.

Header pin-count constraint

The device requires a 19 or 20-pin internal USB 3.0 header on the motherboard; boards with only the older 9-pin USB 2.0 header cannot supply the necessary SuperSpeed lanes. Cable routing and header orientation must match the keyed connector.

PH22 variant with mounting holes

The PH22 version includes two 3 mm mounting holes for custom bracket or panel installation, while the PH21 variant omits these holes. Choose PH22 when a fixed mechanical attachment is required.

Questions about this item

Which PH variant should I pick for my motherboard header?

Choose PH22 for a 19/20-pin header that adds two USB 3.0 Type-A ports with 3 mm mounting holes; PH21 uses a dual-layer 19-pin connector for a single internal USB 3.0 interface.

What does the 19/20-pin header deliver when installed in a desktop?

It converts the motherboard's internal USB 3.0 header into two external Type-A sockets, providing 5 Gbps signalling to front-panel devices.

How does the USB 3.0 interface limit real-world transfer speed?

The USB 3.0 link caps throughput at 5 Gbps, so connected drives or peripherals cannot exceed that bandwidth regardless of their own rated speed.
