Power cable XILENCE XZ183 4-pin for internal PC power (Black)

XILENCE XZ183 is a black 4-pin internal power cable intended for PC use. It features a standard 4-pin (Molex-style) connector for powering hard drives, optical drives and certain peripherals from a compatible power supply. The cable is supplied as a single piece and designed for replacement or extension of internal power leads in desktop computers and workstations. It is compatible with modular power supplies in the X series and A+III series listed by the manufacturer.

Advantages

The XILENCE XZ183 provides a simple, standard connection for legacy drives and peripherals that require a 4-pin Molex-style power plug. Its black finish offers a discreet appearance inside most PC cases and helps keep internal cabling visually consistent. Supplied as a single cable, it allows quick replacement of a worn or missing connector or extension of existing wiring without altering the power supply.

Suitable for (tasks / use cases)

• Powering 3.5" hard drives and 5.25" optical drives in desktop PCs
• Connecting older peripherals and accessories that use 4-pin Molex power
• Replacing a damaged internal 4-pin power lead in a workstation or home computer
• Extending internal wiring to reach additional devices inside a PC case

When it may not be suitable

This cable is not suitable for modern devices that require SATA power connectors or for power delivery to components that need higher-pin proprietary connectors. It is intended for internal use only and is not designed for external or exposed installations. For power supplies or devices outside the listed modular compatibility, verify connector fit and pinout before use.

Key specifications

• Connector type: 4-pin (Molex-style)
• Color: Black
• Quantity: 1 piece
• Intended use: Internal PC power cable for drives and peripherals
• Compatibility: Designed for use with X series and A+III series modular power supplies from the same manufacturer (see compatibility list)

How to use

Power off the computer and disconnect it from mains power before installing the cable. Locate the appropriate 4-pin power output on the modular power supply or an existing internal cable harness, align the 4-pin connector with the socket on the drive or peripheral, and push firmly until it seats. Ensure correct orientation of the connector to match the device pinout and avoid forcing the plug. After installation, tidy cables to maintain airflow and reconnect mains power before powering on the system.

What to consider before purchase

• Confirm that the device you plan to power uses a 4-pin Molex-style connector rather than SATA or proprietary connectors
• Verify physical fit and pinout compatibility with your power supply and target device
• Consider cable length and routing inside your case to ensure the cable reaches the device without strain

Usage recommendations

Use the XILENCE XZ183 only for internal connections in powered-off systems and avoid repeated plugging/unplugging under load. If you are replacing a cable on a modular power supply, consult the power supply manual for the correct module position and compatible connectors.
