Lenovo 4X97B04477 NVIDIA L40S GPU Power Cable KIT

Lenovo 4X97B04477 NVIDIA L40S GPU Power Cable Kit

Overview

The Lenovo 4X97B04477 is a GPU power cable kit designed to supply the high-wattage power connections required by NVIDIA L40S accelerators installed in compatible Lenovo server platforms. At 10 lb, this is a substantial wiring assembly — not a single thin cable — reflecting the multi-connector, high-current topology that L40S-class GPUs demand. If you're deploying L40S cards for AI inference, rendering, or compute workloads in a Lenovo server, this kit provides the internal power harness purpose-built for that configuration rather than relying on generic aftermarket alternatives.

Compatibility

Designed for Lenovo server systems configured with NVIDIA L40S GPUs. The 4X97B04477 is a Lenovo-sourced component intended for use within Lenovo ThinkSystem server platforms that support the L40S accelerator option. Confirm your specific ThinkSystem model's GPU power topology against Lenovo's configuration documentation before ordering — L40S power cabling requirements vary by chassis and riser configuration. This kit is not a universal GPU power cable and should not be substituted into non-Lenovo or non-L40S deployments.

Installation Notes

At 10 lb, route and support this cable assembly carefully inside the chassis — unsupported weight on GPU power connectors is a known cause of intermittent contact failures under vibration. Follow Lenovo's ThinkSystem service guide for cable routing paths and tie-down points specific to your server model. Country of origin is Mexico (UNSPSC 26121629).
