Cable extension set CableMod PRO ModMesh CM-PCAB-16P3KIT-NKKW-3PK-R — 3-pack black & white sleeved PCIe/ATX cable extensions

CableMod PRO ModMesh CM-PCAB-16P3KIT-NKKW-3PK-R is a 3-pack cable extension set in black and white sleeved ModMesh design. These extensions are made to extend standard 16‑pin (PCIe) and 3‑pin (ATX) power connections, providing a cleaner routing option for GPU and PSU cables inside desktop PC builds. The sleeved ModMesh finish offers a consistent two-tone appearance while maintaining flexibility and airflow around connectors.

Advantages

The set simplifies cable management by adding extra length without altering or cutting original PSU and GPU cables. Sleeved ModMesh construction improves the visible aesthetics of a build and helps organize cable runs behind the motherboard tray or along case routing channels. Because the extensions connect directly to existing connectors, swapping components or upgrading hardware is quick and reversible.

Suitable for

• Extending GPU PCIe power cables to reach graphics cards in larger cases
• Improving internal cable appearance for custom or showcase PC builds
• Routing and tidying PSU to motherboard or add-on card power connections
• Temporary extension during component swaps or testing without modifying original cables

Key specifications

• Quantity: 3 cable extensions per pack
• Connector types: 16‑pin (PCIe) and 3‑pin (ATX) power extensions
• Sleeving: ModMesh black and white two-tone sleeved finish
• Compatibility: Compatible with standard 16‑pin PCIe and 3‑pin ATX power connectors from most desktop PSUs and GPUs
• Purpose: Extension cables for power routing and aesthetic customization

How to use

Turn off and unplug the computer before connecting the extensions. Plug the extension’s female end onto the existing PSU or GPU power plug, then connect the male end to the device’s power input. Ensure each connector is fully seated and oriented correctly to avoid misalignment. Route the sleeved cables through the case routing channels or behind the motherboard tray to achieve the desired tidy appearance, and secure them with cable ties if necessary. Reconnect power and verify system operation after installation.

Recommendations

Use these extensions only with compatible standard 16‑pin PCIe and 3‑pin ATX power connectors and do not force connectors into incompatible ports. Avoid excessive bending near connector ends and keep cables clear of hot components and moving parts. For best results, plan cable routing before final assembly and test system stability after installation.
