Lenovo 4XH7A86399 SR655 V3 X16/X16 G5 R3 KIT

Lenovo 4XH7A86399 SR655 V3 PCIe Riser Kit

Overview

The Lenovo 4XH7A86399 is a PCIe riser kit — specifically the X16/X16 G5 R3 configuration — designed to expand slot capacity on the ThinkSystem SR655 V3 server platform. If you're provisioning an SR655 V3 for GPU-dense workloads, high-bandwidth network cards, or storage accelerators that require additional PCIe Gen 5 lanes, this riser kit is the hardware path to get there. The 4XH7A86399 ships factory-new from manufacturing in Mexico.

Compatibility

This riser kit is designed for the Lenovo ThinkSystem SR655 V3 server. The X16/X16 G5 R3 designation indicates dual PCIe Gen 5 x16 slots in a R3 (Riser 3) position — confirm your SR655 V3's riser bay and chassis configuration before ordering. This kit is not interchangeable with SR655 V2 or other ThinkSystem generations; riser assemblies are platform-specific. If you're expanding a different server in the ThinkSystem rack server line, verify the riser part number against Lenovo's compatibility matrix for your exact chassis revision.
