Lenovo 4XH7A87512 SR650 V3 Single CPU GEN4 RISER3 KIT

Lenovo 4XH7A87512 SR650 V3 Single CPU Gen4 Riser 3 Kit

Overview

The Lenovo 4XH7A87512 is a PCIe Gen4 Riser 3 Kit designed for single-CPU configurations of the ThinkSystem SR650 V3 rack server. Riser cards in this slot position expand the available PCIe lane count accessible to the processor — relevant when you need to add more network adapters, storage HBAs, or GPU accelerators beyond what the base slot complement provides. If your SR650 V3 deployment is running short on PCIe capacity for additional cards and the server is populated with a single CPU, this riser kit is the correct expansion path rather than purchasing a new chassis. The 4XH7A87512 ships factory-new at a weight of 2.00 lb and is manufactured in Mexico.

Compatibility

This riser kit is specific to the Lenovo ThinkSystem SR650 V3 platform in single-CPU configuration. It is not interchangeable with dual-CPU SR650 V3 riser kits, with prior-generation SR650 V2 risers, or with other ThinkSystem models such as the SR630 or SR550. Confirm your SR650 V3 chassis is configured for single-CPU operation before ordering — the riser slot count and mechanical form factor differ between single and dual-CPU builds. PCIe Gen4 signaling requires a Gen4-capable CPU and motherboard; the SR650 V3 with Intel Xeon Scalable Gen4 processors meets this requirement. If your server houses two processors, the dual-CPU riser variant is required instead.

Installation Notes

Riser installation in the ThinkSystem SR650 V3 follows Lenovo's standard tool-based procedure: power down and unplug the server, discharge static, and seat the riser assembly into the designated Riser 3 slot on the system board. Verify the riser locks positively into the chassis guide rails before installing any add-in cards. Consult the SR650 V3 Hardware Maintenance Guide for torque specs on any retention screws and for correct cable routing to avoid airflow obstruction across the riser zone.
