Lenovo ThinkStation Mini with i9-14900

This compact desktop pairs a 14th Gen Intel i9-14900 processor with an NVIDIA T400 4GB GDDR6 graphics card. It ships with 16GB DDR5 memory, a 4TB PCIe NVMe SSD and Windows 11 Pro pre-installed. A 300W power supply runs the system in a 7 x 7.25 x 1.5 inch chassis weighing 3.1lb.

Suits professionals needing multi-display

The four display outputs — HDMI, one DisplayPort and three mini DisplayPort — drive multiple monitors from a small footprint. Buyers who need more than 16GB memory, additional internal drive bays or a higher-wattage power supply for larger graphics cards should consider a larger form factor.

300W power supply limits graphics upgrades

The fixed 300W unit powers the included T400 and the 24-core CPU but leaves no headroom for discrete cards requiring auxiliary power connectors. If your workload demands a more powerful GPU, this chassis cannot accommodate it.

Questions about this item

How does the 24-core i9-14900 behave inside this 7 × 7.25 × 1.5 in chassis?

The 2.00 GHz base clock runs within the 300 W supply; turbo reaches 5.8 GHz when thermals allow, and the 36 MB cache keeps feed rates high for compile or render bursts.

What does the PCI Express x16 link mean for the T400 4 GB GDDR6 card?

The slot provides full x16 bandwidth so the GPU can move textures and compute buffers without a bottleneck from the bus.

Will the 16 GB DDR5 SO-DIMM fit the two SODIMM sockets in this mini frame?

The board accepts DDR5 SO-DIMMs; the kit supplied occupies one slot, leaving the second free for a later upgrade.
