CBL-PWEX-1136YB-25 Supermicro 25cm Cable

High-Density Server Power Distribution Harness featuring MicroHi Splitter Topology with the CBL-PWEX-1136YB-25

The CBL-PWEX-1136YB-25 is a Supermicro MicroHi power cable assembly engineered for controlled internal power distribution in modern rack servers, GPU nodes, and dense storage platforms where board-level connectors and cable routing margins are tight. By converting 1x MicroHi 2x4 (male) into 2x MicroHi 2x2 (male) outputs, the CBL-PWEX-1136YB-25 supports modular power delivery to backplanes, risers, and auxiliary device headers without introducing unnecessary cable slack or unmanaged branching.

In current CPU and GPU server architectures, stability under transient load is strongly influenced by connector fit, harness integrity, and repeatable routing across airflow paths. The CBL-PWEX-1136YB-25 is optimized as a 25cm harness with 2 x 25cm leg lengths to align with short-run chassis layouts, helping reduce strain on headers and minimizing obstruction around PCIe expansion zones, storage bays, and service access points. In service and lab environments, the CBL-PWEX-1136YB-25 enables fast replacement of MicroHi power leads to restore validated power topology and reduce troubleshooting time during component swaps.

Why Choose the CBL-PWEX-1136YB-25?

The CBL-PWEX-1136YB-25 provides an enterprise-safe method to split MicroHi power from a single 2x4 source into two 2x2 destinations while maintaining predictable cable management in compact server interiors. This supports consistent build standards, simplifies scaling across identical chassis configurations, and strengthens operational reliability through correct harness-to-chassis compatibility and repeatable routing.

Supermicro designs power harnesses to match chassis mechanical constraints and board-level power connector specifications, prioritizing fit, long-term serviceability, and integration with current data centre assembly practices. This approach helps maintain platform compliance across upgrades and reduces risk when deploying spare or replacement internal power distribution parts.

Key Applications:

• Server internal power distribution
• Chassis harness replacement and spares
• Lab validation and integration builds
• Data centre break/fix maintenance
