Product information

Description

The Chieftec ADP-CT3 is an internal interface card that provides compatibility for front-panel or external devices using a USB 3.1 Gen2 20‑PIN Key‑A connector by converting that connection to a standard 19‑PIN USB 3.1 Gen1 male header. It enables connection to motherboards that lack the specific internal 20‑pin Key‑A header while supporting USB Type‑A host devices and maintaining a compact form factor (22 × 28 × 10 mm) and lightweight design (25 g).

Advantages

The adapter allows legacy or nonstandard front panel USB 3.1 Gen2 Key‑A connectors to be used with mainstream motherboards through a USB 3.1 Gen1 19‑pin header, supports data transfer rates up to 5 Gbit/s, and operates at a 5 V output. Its small dimensions and low weight simplify installation in constrained spaces without requiring changes to the motherboard.

Suitable for

Connecting front-panel USB ports with a USB 3.1 Gen2 20‑pin Key‑A plug to motherboards lacking that header
Adapting external USB Type‑A host interfaces to a 19‑pin USB 3.1 Gen1 internal header
Compact PC builds and systems with limited internal space

EAN: 753263077288
Interface conversion: USB 3.1 Gen2 20‑PIN Key‑A → USB 3.1 Gen1 19‑PIN male header

Output voltage: 5 V
Dimensions: 22 mm (W) × 28 mm (D) × 10 mm (H)
Weight: 25 g

How to use

Connect the device or front-panel cable with the USB 3.1 Gen2 20‑pin Key‑A connector to the ADP-CT3 adapter, then plug the adapter's standard 19‑pin USB 3.1 Gen1 male header into an available USB 3.1 Gen1 (19‑pin) internal header on the motherboard. Ensure correct pin alignment when inserting the header to avoid misconnection. After physical installation, power on the system; the connected device should be recognized by the operating system as a USB Type‑A interface operating at supported speeds.

Usage recommendations

Use the ADP-CT3 in systems where the motherboard lacks a dedicated 20‑pin Key‑A internal header. Verify motherboard documentation for the location and orientation of the 19‑pin USB 3.1 Gen1 header before installation, and avoid forcing the connector to prevent damage to pins or the adapter.
