Small black circuit board with one 19-pin USB 3.0 header and two 9-pin USB 2.0 connectors

Fervit

Fervit USB 3.0 19pin to 2× USB 2.0 9pin header adapter

SKU CH-15HE-SRVBA

Converts a motherboard USB 3.0 19-pin header into two USB 2.0 9-pin ports with 480 Mbps speed and 500 mA per port

  • Adds two USB 2.0 headers from one USB 3.0 19-pin motherboard connector
  • Built-in USB 2.0 hub chipset delivers up to 480 Mbps data speed
  • Each port supplies DC 5 V 500 mA current for connected devices
  • Extends a single 19-pin header to dual 9-pin female connectors
  • Simple internal adapter multiplies front-panel or header USB ports

One-to-two USB 3.0 header adapter

This Fervit adapter converts a single 19-pin USB 3.0 motherboard header into two 9-pin USB 2.0 connectors. It is designed for PC builders who need extra front-panel or internal USB ports but only have one high-speed header available. A built-in USB 2.0 hub chipset manages the split without requiring additional drivers or software configuration.

Upgrading from a single occupied header

When a chassis provides two USB 2.0 front-panel cables but the motherboard offers only one 19-pin header, this adapter eliminates the need to leave one port unused. The upgrade is worthwhile whenever the case layout demands both connectors simultaneously and no spare USB 2.0 headers exist on the board. It does not add USB 3.0 bandwidth; the two new ports operate at USB 2.0 speeds.

Two ports at 480 Mbps with 500 mA each

Each 9-pin connector delivers up to 480 Mbps data throughput and 500 mA at 5 V, suitable for keyboards, mice, card readers or USB audio devices. The hub chipset shares the single upstream 19-pin link, so combined throughput cannot exceed the USB 2.0 limit. Devices that require USB 3.0 transfer rates or higher current draw will not perform at their rated capability on these ports.

Questions about this item

Does the 19-pin USB 3.0 header on my motherboard provide enough clearance for this adapter's connector?

The adapter plugs directly into a standard 19-pin USB 3.0 motherboard header and presents two 9-pin USB 2.0 headers, so it fits any board with that 19-pin keying.

Which header do I plug in first, and how do I avoid bending the 19-pin connector?

Align the keyed 19-pin plug with the motherboard header, press straight down until fully seated, then attach your front-panel or accessory cables to the two 9-pin headers.

If the onboard HUB chipset fails, can I replace just that component or must I swap the whole adapter?

The USB 2.0 HUB chipset is soldered on the PCB, so a chipset failure means replacing the entire adapter; each port still delivers 5 V at 500 mA while it works.
