CableMod C-Series Pro Cable Assembly Variant B 90cm 16-pin to 4×8-pin PCIe Carbon

The CableMod C-Series Pro Cable Assembly Variant B 90cm converts a single 16-pin power input into four 8-pin PCIe outputs, enabling power distribution to multiple graphics cards or GPU modules in modular PC builds. The 90 cm length offers routing flexibility inside mid-tower and full-tower enclosures while the carbon finish provides a neutral aesthetic that integrates with many build styles. The assembly is intended to comply with standard PCIe power specifications and is designed for use in systems with modular power supplies and compatible motherboard or GPU connectors.

Advantages

This cable assembly provides a compact and organized solution for supplying power to multiple PCIe devices from a single 16-pin source. The 90 cm length reduces the need for additional extenders, while the four separate 8-pin PCIe connectors maintain a consistent layout for easier cable management. The carbon finish offers visual uniformity in builds that match or complement darker components and sleeving. The design focuses on reliable physical fit and compatibility with standard PCIe power requirements.

Suitable for

• Multi-GPU or multi-accelerator workstation and gaming PCs that require multiple 8-pin PCIe power connections
• Custom PC builds using modular power supplies with a 16-pin to 4×8-pin conversion
• Systems where cable routing flexibility and a uniform appearance are important

Key specifications

• Cable type: 16-pin to 4×8-pin PCIe cable assembly
• Length: 90 cm total cable length
• Connector layout: one 16-pin input to four separate 8-pin PCIe outputs
• Finish: carbon color sleeving
• Compatibility: designed for standard SATA/PCIe power specifications and modular PSUs with compatible 16-pin outputs

How to use

Connect the 16-pin end of the CableMod C-Series Pro Variant B to the corresponding 16-pin power output on a compatible modular power supply. Route the 90 cm cable inside the case to each target device and plug the 8-pin PCIe connectors into the GPU or accelerator power sockets, ensuring secure and fully seated connections. Arrange and secure the cables to avoid contact with moving parts and to maintain airflow. Verify that the power supply and target devices support the required power draw before enabling the system.

Recommendations

Use this cable only with power supplies and devices that explicitly support a 16-pin to multiple 8-pin PCIe conversion. Confirm total power draw for all connected PCIe devices and ensure the power supply provides adequate current on the relevant rails. For optimal cable management and airflow, route the cable along case channels and secure with ties or clips; avoid sharp bends and maintain clearance from fans and heat sources.
