CBL-PWEX-0582 Supermicro 30cm Cable

Enterprise PCIe/GPU Power Distribution Cable Assembly with the CBL-PWEX-0582 for Supermicro Platforms

The CBL-PWEX-0582 is an internal power cable assembly engineered to distribute chassis PSU auxiliary power to PCIe add-in cards in dense Supermicro server and workstation designs. In GPU-accelerated nodes where CPU platforms and GPU generations drive sustained load profiles, the integrity of the 12V feed path is critical to maintaining stable boost behavior and avoiding transient-induced faults under AI, VDI, and HPC scheduling.

Designed for modern PCIe expansion topologies, the CBL-PWEX-0582 routes one 8-pin internal power input to dual 6+2-pin PCIe outputs, aligning with common GPU power inlet requirements while supporting flexible cable management in constrained airflow zones. The 30cm length targets typical PSU-to-riser and PSU-to-GPU harness distances, helping keep service loops controlled and reducing mechanical strain on GPU headers during hot-aisle maintenance. As a service replacement or upgrade path, the CBL-PWEX-0582 supports clean integration into storage- and accelerator-dense chassis where power cabling must coexist with backplanes, fans, and PCIe Gen4/Gen5 signal routing without compromising serviceability.

Why Choose the CBL-PWEX-0582?

The CBL-PWEX-0582 delivers a practical density-to-performance advantage by enabling a single PSU feed to supply two PCIe auxiliary power endpoints, simplifying harnessing for multi-GPU configurations. This reduces internal cabling complexity, improves maintenance access to PCIe slots, and supports scalable accelerator rollouts while maintaining enterprise reliability expectations for continuous operation.

Supermicro engineering emphasizes platform consistency, validated component integration, and service-friendly internal architecture. The CBL-PWEX-0582 follows this approach with RoHS and REACH compliance and is aligned with modern data center operational standards where predictable parts interchangeability and controlled change management are required.

Key Applications:

• GPU compute and AI training nodes
• HPC accelerator clusters
• Virtualization and VDI with discrete GPUs
