Lenovo 4X97A85028 400mm 2x6+4 H100 GPU Power Cable

Overview

The Lenovo 4X97A85028 is a 400mm internal power cable terminated with a 2x6+4 connector, purpose-built to route GPU power within Lenovo server platforms hosting NVIDIA H100 accelerators. At 400mm, the cable provides enough reach to manage clean routing inside dense GPU-configured chassis without forcing sharp bends that stress connector housings or restrict airflow — both real concerns in high-wattage GPU nodes running continuous AI inference or training workloads.

Compatibility

This cable is a Lenovo factory component designed for use in Lenovo ThinkSystem server platforms configured with NVIDIA H100 GPU options. The 2x6+4 termination matches the power connector standard used on H100 SXM and PCIe variants in supported Lenovo configurations. Verify the specific ThinkSystem chassis and GPU slot mapping against your server's hardware maintenance manual before ordering — GPU power cable routing is chassis-revision-sensitive, and Lenovo periodically releases connector variants tied to specific board revisions. This is a Lenovo-sourced part (MPN 4X97A85028); substituting generic or third-party cables in H100 nodes risks tripping OCP/OVP protection circuits and voiding platform support.

Installation Notes

Seat both ends fully until the latch clicks before powering on — a partially seated 2x6+4 connector under H100 load levels (up to 700W SXM variant) will arc and damage the socket. Route the 400mm length along the designated cable channel; do not loop excess cable across airflow paths in a GPU tray, as thermal throttling on adjacent GPUs is a documented consequence of blocked airflow in high-density nodes.
