Lenovo ThinkStation Mini Desktop i9-14900 T400 4GB 8GB DDR5 512GB NVMe Win 11 Home 300W

Compact workstation core

The Lenovo ThinkStation Mini delivers a 14th Gen Intel Core i9-14900 processor with 24 cores and 32 threads in a 7 x 7.25 x 1.5 inch chassis. It targets professionals who need multi-threaded compute for CAD, rendering or data analysis but lack space for a full tower. The 300 W power supply and integrated NVIDIA T400 4 GB GDDR6 graphics keep the footprint small without external power bricks.

Build integration

The system ships with 8 GB of DDR5 SO-DIMM memory and a 512 GB PCIe NVMe SSD, leaving two memory slots and additional M.2 bays open for future expansion. Video output covers HDMI, one full-size DisplayPort and three mini-DisplayPort connectors, driving up to four displays from a single device. WiFi 6, Bluetooth 5.3 and a wired RJ-45 port handle networking without extra cards, while a USB 3.2 Type-C port and combo audio jack sit on the front for quick peripheral access.

Sustained load behaviour

The 36 MB L3 cache and 5.8 GHz maximum turbo frequency let the 8 performance cores maintain high throughput during long compile or simulation runs. The 300 W PSU and compact thermal design are sized for the factory configuration; adding higher-power components later would require verifying headroom. Under continuous multi-core workloads the processor will balance clock speeds against thermal limits rather than holding peak frequency indefinitely.
