Internal power cable PHANTEKS PH-CB-DRGB3P — 3-pin to 2× Molex (3-pin), black/grey

The PHANTEKS PH-CB-DRGB3P internal power cable converts a single 3-pin connector to two Molex (3-pin) plugs for use inside desktop computer cases. With a straight 3-pin input and dual Molex outputs, this cable facilitates connection of legacy peripherals, additional fans with Molex connectors, or other internal devices that require the Molex power interface. The cable is finished in a black and grey colour scheme to match typical interior builds while keeping wiring tidy and accessible.

Advantages

This cable provides a simple and reliable method to split one 3-pin power output into two Molex (3-pin) power connectors without modifying existing connectors. The straight 3-pin connector offers a compact connection point, and the dual Molex plugs enable powering multiple legacy devices or accessories from a single header. The distinct black and grey colouring helps visually separate this harness from other cables in the system and supports clean cable routing.

Suitable for

• Connecting Molex-powered devices such as older hard drives, optical drives, or accessories inside a PC case
• Splitting a single 3-pin power source to feed two Molex-equipped peripherals
• Internal cable routing in desktop systems where additional Molex power outputs are required

Key specifications

• Input connector: 3-pin
• Output connectors: 2 × Molex (3-pin)
• Intended use: Internal power distribution inside desktop PC cases
• Colour: Black and grey

How to use

Power down the system and disconnect it from mains before installing the cable. Insert the straight 3-pin connector into the corresponding header or cable on the power source, taking care to align pins correctly. Route the cable inside the case to avoid obstructing fans or airflow, then connect each Molex plug to the target devices. Re-check all connections for secure fit and restore power to verify that connected devices receive power as expected.

Recommendations

Use this adapter only for internal power connections and ensure compatibility of voltage and pin assignments with target devices. Avoid using Molex adapters to draw excessive current beyond the capabilities of the original 3-pin power source. Keep cables clear of moving parts and hot components to maintain system safety and reliability.
