Lenovo 4X97A82947 SR650 V3 Single CPU X16X16 G5 Riser3 Cable

Overview

The Lenovo 4X97A82947 is a PCIe Gen 5 riser cable assembly designed for the ThinkSystem SR650 V3 rack server in single-CPU configurations. It supports the Riser 3 slot position and provides dual x16 PCIe lanes — the internal interconnect that allows full-bandwidth PCIe Gen 5 add-in cards to seat in the riser without signal degradation from an undersized cable. If you're expanding a single-socket SR650 V3 build with high-throughput cards in the Riser 3 position, this cable is the required physical link between the system board and the riser card.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 (single-CPU populated configurations). The 4X97A82947 targets the Riser 3 slot and provides x16+x16 PCIe Gen 5 connectivity. Confirm your SR650 V3 chassis is configured for single-CPU operation before ordering — dual-CPU configurations require a different riser cable assembly. Verify your riser card bracket and slot assignment in the SR650 V3 system documentation before installation to avoid misrouting.

Installation Notes

Weight is 10.00 lb — account for cable management when routing within the chassis. Country of origin is Mexico. Route the cable according to Lenovo's internal cable routing guide for the SR650 V3; improper routing can restrict airflow or create mechanical stress on the PCIe connector. No additional tools beyond standard ESD precautions are specified in the available evidence — follow Lenovo's SR650 V3 maintenance manual for torque and seating requirements on the riser connector.
