Lenovo 4X97B04860 SR650/A V4 GPU Power Cable KIT

Lenovo 4X97B04860 SR650/A V4 GPU Power Cable Kit

Overview

The Lenovo 4X97B04860 is a factory-new GPU power cable kit designed for ThinkSystem SR650 and SR650A V4 rack servers. When deploying GPU accelerators in these platforms — compute nodes, AI inference workloads, or visualization clusters — proper power cabling to the GPU is a hard requirement, not optional. Using the correct OEM cable assembly ensures connector fit, conductor gauge, and strain-relief geometry match what Lenovo's backplane and GPU bracket geometry expect. The 4X97B04860 eliminates the guesswork of aftermarket alternatives that may not clear internal chassis features or reach the correct GPU slot power connectors without stress on the harness.

Compatibility

This cable kit is specified for the Lenovo ThinkSystem SR650 V4 and SR650A V4 2U rack server platforms. It is NOT a universal GPU power cable — do not attempt to use it in SR630, SR860, SR950, or prior-generation V2/V3 SR650 configurations, where connector routing, cable length, and locking tab geometry differ. Verify the target chassis is specifically a V4-generation SR650 or SR650A before ordering.

Installation Notes

Route cable harness per Lenovo's ThinkSystem SR650/SR650A V4 hardware maintenance manual — improper routing across hot components or obstruction of airflow baffles can trigger thermal events on GPU workloads. Ensure server power is fully removed and capacitors discharged before connecting or disconnecting GPU power leads. No special tooling is listed in available evidence, but standard ESD precautions apply when working inside the chassis.
