Phanteks PH-CB-Y4P Internal Power Cable

The Phanteks PH-CB-Y4P internal power cable is a Y-splitter that lets you connect two 4-pin PWM fans to a single 4-pin PWM fan header. Designed for internal PC cooling setups, it provides a simple way to expand fan connections without using additional motherboard headers or controllers.

Advantages

The cable supports PWM control through the single motherboard header, maintains standard 4-pin connector compatibility, and has a compact design that keeps cable routing straightforward inside the chassis.

Suitable for

• Connecting two 4-pin PWM case fans to one motherboard fan header
• Expanding fan connections in compact builds with limited headers
• Combining multiple fans under a single PWM control source

Key specifications

• Brand: PHANTEKS
• Model / MPN: PH-CB-Y4P
• EAN: 0886523300526
• Connector: 1 × 4-pin PWM female to 2 × 4-pin PWM male
• Type: Internal Y-splitter power cable for fans

How to use

Plug the female 4-pin PWM connector into the motherboard fan header, then connect up to two 4-pin PWM fans to the male connectors. Ensure connectors are aligned correctly before applying pressure. Verify BIOS or fan-control software recognizes the combined fans and adjust PWM profiles as needed.

Recommendations

Use this Y-splitter when the combined current draw of the connected fans does not exceed the motherboard header's rated current. If unsure, consult the motherboard specifications or use a dedicated fan hub or powered controller.
