Lenovo 7XH7A05899 Mech SR650 2ND GPU Upgrade KIT

Lenovo 7XH7A05899 SR650 Second GPU Upgrade Kit

Overview

The Lenovo 7XH7A05899 is the mechanical upgrade kit required to install a second GPU into the ThinkSystem SR650 server. If your SR650 deployment calls for dual-GPU compute — whether for parallel inference workloads, multi-stream video analytics, or accelerated data processing — this kit provides the mechanical hardware necessary to seat and secure the second card within the server chassis. Without it, the SR650 chassis lacks the structural components to support a second GPU installation. Weighing 0.35 lb, the 7XH7A05899 ships as a compact assembly (9.40 x 6.10 x 2.20 in) manufactured in Mexico.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 (7X05, 7X06 series) 2U rack server. This kit is not a universal GPU bracket — it is chassis-specific. Confirm your SR650 generation and existing GPU configuration before ordering. Pairing this with a compatible rack server GPU requires verifying that your SR650's power supply and PCIe slot configuration support dual-GPU operation. Consult the SR650 Hardware Maintenance Manual for supported GPU combinations and power envelope limits before purchasing a second GPU alongside this kit.

Installation Notes

Installation is a mechanical procedure performed inside the SR650 chassis — the server must be powered down and removed from the rack before beginning. Standard data center ESD precautions apply. Because this is a server upgrade kit targeting a specific chassis generation, verify the SR650 system board revision supports the intended second GPU model. GPU thermal and power constraints for the SR650 are documented in Lenovo's official maintenance guides and should be reviewed prior to committing to a specific GPU pairing.
