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.
