USB2.0-kabel mainboard splitter 90 mm 2x USB-pinheader

When your motherboard has only one free USB 2.0 header but your build calls for two internal devices, this 90 mm splitter cable solves the problem in seconds. It plugs directly into the 9-pin header on your mainboard and provides two standard 9-pin male headers, so you can connect a front-panel card reader, an internal Bluetooth module, or a liquid cooling controller without sacrificing connectivity. The compact length keeps cable clutter to a minimum inside the case, while the standard pinout ensures compatibility with virtually any ATX, micro-ATX, or mini-ITX board.

Key specifications

• USB standard: USB 2.0 (Hi-Speed, 480 Mbps)
• Connector A (input): 1x 9-pin USB 2.0 motherboard header, female
• Connector B (output): 2x 9-pin USB 2.0 motherboard header, male
• Cable length: 90 mm
• Colour: black
• Material: PVC jacket, copper conductors
• Voltage: 5 V (via USB)
• Current: up to 500 mA per port
• Shielding: unshielded
• Installation: plug-and-play, no drivers required

Why choose it

This splitter is a reliable way to expand your internal USB 2.0 connectivity without adding an internal hub. It uses a simple passive design that draws power from the motherboard header, so there are no external adapters or extra cables to manage. The 90 mm length is ideal for routing between nearby headers and keeps the build tidy. The black PVC jacket blends into any case interior, and the standard 9-pin connectors fit securely to prevent accidental disconnection.

Ideal use cases

• Connecting a front-panel USB 2.0 card reader and an internal Bluetooth module simultaneously
• Adding a second header for a fan controller or RGB lighting hub that uses USB 2.0
• Providing an extra internal port for a liquid cooling pump or sensor panel
• Simplifying cable management in small form factor builds where space is limited

Good to know

The splitter is compatible with any standard USB 2.0 9-pin motherboard header. Since it is a passive splitter, the total current available is limited by the motherboard header (typically 500 mA). For devices that require more power, an active internal USB hub is recommended. The cable is unshielded, which is fine for short runs inside a PC case, but avoid routing it next to high-power components like graphics cards or power supply cables to minimize interference.
