The Lenovo ThinkSystem ST45 V3 is a versatile and compact single-socket tower server designed for small office/home office (SOHO), branch office, retail, and education environments. Engineered to offer enterprise-grade reliability and serviceability in a quiet and compact chassis, this server supports AMD EPYC 4004 series processors with up to 12 cores and 24 threads, providing powerful compute performance with up to 64 MB cache and a maximum TDP of 65W.

Equipped with advanced TruDDR5 ECC UDIMM memory support, the ST45 V3 allows up to 64 GB of RAM via two DIMMs running at up to 5600MHz for robust data integrity and performance. Storage flexibility is a key highlight featuring three 3.5" non-hot-swap bays, one 2.5" bay, and two M.2 NVMe boot options enabling varied and scalable configurations.

Expansion capabilities include a full-height PCIe Gen3 x16 slot and a PCIe Gen3 x1 slot, accommodating additional I/O cards and networking adapters. Networking comes integrated with embedded 1GbE, while power supply choices range from an ATX 300W Gold to a more robust 500W Platinum with ErP Lot9 energy compliance.

Management is streamlined with Lenovo's XClarity Provisioning Manager Lite, a USB key-based tool for quick system setup, firmware updates, OS deployment, and diagnostics, though it lacks an XClarity Controller (XCC) processor. The ST45 V3 is offered with configurable compute and memory options and backed by warranty coverage of up to 3 years, making it an ideal infrastructure foundation for offices requiring high reliability without a traditional data center footprint.
