Compact workstation for professional workloads
This Lenovo ThinkStation Mini PC pairs a 14th Gen i9-14900 processor with 24 cores and 32 threads with an NVIDIA T400 4GB GDDR6 graphics card. It targets engineers, designers and analysts who need multi-threaded compute and certified drivers in a 7 IN by 7.25 IN by 1.5 IN chassis that weighs 3.1lb.
Verify display outputs and memory headroom
The system provides one HDMI, one full-size DisplayPort and three mini-DisplayPort connectors, so confirm your monitors match these interfaces. Only 8GB of DDR5 SO-DIMM memory is installed; check whether your applications require additional capacity before ordering.
300W power supply manages thermals and acoustics
A 300W internal PSU feeds the CPU, the T400 GPU and the 256GB PCIe NVMe SSD within the small enclosure. Expect fan activity to rise under sustained multi-core loads while remaining moderate during typical office or CAD sessions. The compact layout limits passive cooling surface, so ensure adequate airflow around the unit.
