InLine USB 2.0 to 3.0 Internal USB Header Cable 33449I

The InLine USB 2.0 to 3.0 internal USB header cable (0.15 m) provides an internal adapter for connecting USB 3.0 devices to a motherboard's USB 2.0 header. The cable features a male 9-pin USB 2.0 header on one end and a female 19-pin USB 3.0 connector on the other, enabling compatibility between older motherboards and newer USB 3.0 peripherals while keeping the internal layout tidy.

Advantages

This adapter cable enables the use of USB 3.0 devices on systems with USB 2.0 header connectors without requiring external converters. Its short 0.15 m length reduces cable clutter inside the PC case. The cable preserves a direct internal connection, maintaining signal routing through the motherboard header for simple installation and reliable operation.

Suitable for

• Connecting one USB 3.0 internal device to a motherboard USB 2.0 header
• Upgrading older systems to support USB 3.0 peripherals internally
• Maintaining a neat internal cable layout in desktop PCs

How to use

Power off the computer and open the case. Locate the motherboard’s USB 2.0 header and insert the male 9-pin connector onto the header, observing the correct pin orientation.

Recommendations

Use this cable for internal connections only; do not expose the connectors to moisture or excessive mechanical stress. Because the motherboard header is USB 2.0, maximum data transfer speeds will be limited to USB 2.0 performance when a USB 3.0 device is connected through this adapter.
