Mini workstation for professional workloads

The Lenovo ThinkStation Mini PC combines a 14th Gen Intel 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 CPU performance and certified drivers in a 7 in by 7.25 in footprint. The 36 MB cache and 5.8 GHz maximum turbo frequency support demanding calculations and visualisation tasks.

Build integration and expandability

The system arrives with 8 GB of DDR5 SO-DIMM memory and a 256 GB PCIe NVMe SSD installed, leaving the second SO-DIMM slot and additional M.2 bays available for future upgrades. A 300 W internal power supply drives the platform without an external brick. Video outputs include HDMI, one full-size DisplayPort and three mini DisplayPort connectors for up to four displays. WiFi 6, Bluetooth 5.3 and RJ-45 Ethernet handle wired and wireless networking.

Thermals, acoustics and power

The compact 1.5 in height chassis uses a blower-style cooler to exhaust heat through the rear vent, keeping the 14900 and T400 within thermal limits during sustained loads. Fan noise remains low at idle and rises to a moderate level under full CPU and GPU utilisation. The 300 W power supply provides sufficient headroom for the configured components while maintaining efficient operation in typical office environments.

Domande su questo articolo

Does the 300 W power supply limit the i9-14900 when all 24 cores run at 5.8 GHz for hours?

The 300 W PSU is sized for the base 2.00 GHz configuration; sustained 5.8 GHz turbo across 24 cores can exceed that budget, so the CPU will throttle to stay within the power envelope.

How loud and hot does the Mini PC get when the NVIDIA T400 and i9-14900 run flat-out all day?

The compact 7 x 7.25 x 1.5 in chassis relies on a small internal fan; expect noticeable fan noise and warm exhaust temperatures under continuous combined CPU and GPU load.

The box shows only a USB keyboard and mouse — do I need to supply my own monitor and cables?

Yes, no display is included; you must provide a monitor with HDMI, DisplayPort or mini-DisplayPort input and the matching cable.
