CableMod 4-pin ATX Cable Extension CM-PCAB-4ATX-N45KK-2PK-R 45 cm Black

CableMod 4-pin ATX Cable Extension CM-PCAB-4ATX-N45KK-2PK-R 45 cm Black is a pair of sleeved 4-pin ATX extensions designed to lengthen motherboard CPU power leads by 45 cm. The extensions enable tidier cable routing and easier positioning of the power supply or motherboard during PC assembly and upgrades. Constructed for compatibility with standard 4-pin ATX CPU power connectors, the black sleeving provides a neutral aesthetic that integrates with a wide range of system builds.

Advantages

The two-pack design offers immediate redundancy and the ability to extend multiple cables at once without purchasing separate items. Each extension uses a durable sleeved outer layer to protect the internal conductors and to improve cable management by reducing tangles and clutter. The 45 cm length gives additional reach for non-standard case layouts or when relocating the power supply, while maintaining the standard 4-pin form factor for reliable electrical contact.

Suitable for

• Extending CPU power leads in desktop PC builds
• Improving cable management in mid-tower and full-tower cases
• Providing extra length for custom or non-standard component placement
• Temporary connections during system testing or component swaps

Key specifications

• Connector type: 4-pin ATX (CPU power)
• Quantity: 2 extensions per pack
• Length: 45 cm per extension
• Colour: black sleeved cable
• Compatibility: standard 4-pin ATX motherboard and PSU headers

How to use

Turn off the system and disconnect power before installing the extensions. Align the male and female 4-pin connectors of each extension with the corresponding CPU power socket on the power supply and the motherboard, ensuring the clip and keying match before applying firm, even pressure. Route the sleeved cable along the intended path and secure it with cable ties or routing channels in the case to maintain a tidy layout. After installation, reconnect power and verify the system boots and the CPU power rail functions normally.

Recommendations

Use the extensions only with matching 4-pin ATX connectors and within typical desktop PC operating conditions. Avoid sharp bends near the connector ends and secure cables to prevent strain on the plugs. If you experience instability after fitting extensions, recheck connections and consult PSU or motherboard documentation to ensure proper power delivery.
