Lenovo 4XH7A82907 SR650 V3 X16/X16 G5 RISER3 KIT

Lenovo 4XH7A82907 SR650 V3 x16/x16 Gen 5 Riser 3 Kit

Overview

The Lenovo 4XH7A82907 is a PCIe Gen 5 x16/x16 Riser 3 Kit designed for the ThinkSystem SR650 V3 rack server. It extends the server's internal PCIe expansion capacity by adding a third riser slot position, enabling deployment of additional high-bandwidth cards — such as network adapters, storage HBAs, or GPU accelerators — without consuming slots already occupied by primary I/O or compute cards. If your SR650 V3 configuration is running short on available PCIe real estate for security appliances, video capture cards, or storage expansion, this kit is the targeted fix.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 rack server platform. The x16/x16 Gen 5 configuration means both slots operate at full PCIe 5.0 x16 electrical bandwidth — relevant when pairing high-throughput cards that would otherwise bottleneck on a shared or bifurcated slot. Verify your SR650 V3 chassis configuration and existing riser population before ordering; riser slot availability depends on which other riser kits are already installed. This kit occupies the Riser 3 position specifically — it does not substitute for Riser 1 or Riser 2 assemblies. Consult your server expansion components inventory and the SR650 V3 configuration guide to confirm slot compatibility with your installed processor and backplane combination.

Installation Notes

Installation requires access to the SR650 V3 chassis interior. The riser assembly slots into the dedicated Riser 3 mechanical bay and connects to the system board via the corresponding PCIe connector — no additional power cabling is required for the riser card itself, though cards installed into it may require supplemental power. Ships from MX (Mexico). Weight is 10 lb, which accounts for the riser bracket and card assembly. Follow the ThinkSystem SR650 V3 Hardware Maintenance Guide for proper torque and seating procedures to avoid PCIe connector damage during installation.
