Fervit USB 3.0 20-pin to dual 19-pin header adapter with LED

SKU CH-0B15-42P1H

Connects a motherboard 20-pin header to two 19-pin USB 3.0 Type-A ports and includes an LED indicator

  • Connect two USB 3.0 devices via dual 19-pin headers from one 20-pin motherboard connector
  • LED indicator confirms active power and data connection at a glance
  • Flat PCB design fits tight internal spaces without blocking adjacent headers
  • Direct 20-pin to dual 19-pin wiring enables full USB 3.0 throughput per port
  • Female Type-A ports accept standard USB 3.0 plugs for external drives or front-panel access

Dual 19-pin header adapter

This Fervit adapter converts a motherboard 20-pin USB 3.0 header into two 19-pin box-header slots. Each slot presents a standard USB 3.0 Type-A female port for external devices. The flat PCBA design fits tight internal spaces and includes an integrated LED indicator. It suits builders adding front-panel or rear-bracket USB ports to a system with a single internal header.

Sustained-load behaviour

The passive PCB carries USB 3.0 signals without active components, so throughput depends on the host controller and attached devices. No thermal throttling occurs because there is no power regulation on the board. The LED simply shows header power presence and does not affect signal integrity during long file transfers.

Compatibility check

Verify that your motherboard provides a 20-pin internal USB 3.0 header with the standard pinout. Ensure the chassis has room for the flat PCBA and that the 19-pin box-header connectors match your front-panel or bracket cables. The adapter draws no auxiliary power, so no extra power-supply connectors are required.

Questions about this item

How much heat does the 20-pin header adapter generate when running all day?

The flat PCBA has no active components, so it produces negligible heat during continuous USB 3.0 data transfer.

What must I already own to use the dual USB 3.0 Type-A female ports?

You need a motherboard with an internal 20-pin USB 3.0 header and external USB 3.0 devices with Type-A plugs.

Will the 19-pin box-header slot work with older USB 2.0 headers on my board?

No, the 19-pin slot is wired for USB 3.0 signals only and is not compatible with USB 2.0 19-pin headers.
