This is a CPU-only upgrade/spare-parts kit for Lenovo's ThinkSystem SR650 V3 rack server — not a complete server, just the processor itself packaged as an official Lenovo option kit for adding or replacing a CPU in a compatible SR650 V3 chassis. The processor is an Intel Xeon Silver 4514Y: a 16-core server chip running at a 2.0GHz base clock with a 150W TDP, part of Intel's Xeon Scalable Silver tier aimed at mainstream two-socket server workloads (virtualization hosts, general enterprise applications) rather than the highest-end Platinum/Gold compute-heavy tiers. As the listing states, it ships without a heatsink/fan — buyers need the corresponding SR650 V3 heatsink kit and must confirm BIOS/firmware and socket compatibility with their specific server configuration before installing.
