Compact workstation for professional workflows

The Lenovo ThinkStation Mini packs a 14th Gen Intel Core i9-14900 processor with 24 cores and 32 threads into a 7 by 7.25 by 1.5 inch chassis. It ships with 16GB of DDR5 memory and an 8TB PCIe NVMe SSD, ready for demanding business applications. Windows 11 Pro is pre-installed.

Sustained multi-threaded performance

The 36MB L3 cache and 5.8GHz maximum turbo frequency allow the processor to maintain high throughput during extended rendering or compilation tasks. The 300W power supply delivers stable current to the CPU and the NVIDIA T400 4GB GDDR6 graphics card without throttling under continuous load.

Thermal and acoustic profile

The small form factor relies on an integrated cooling solution that keeps the system quiet during typical office workloads. Power draw stays within the 300W budget, so heat output remains low enough for a desk-side placement without additional ventilation.

Questions about this item

How loud and hot does the 300W PSU and i9-14900 get under sustained all-day workloads?

The 300W power supply and 14th Gen i9-14900 with 24 cores are built for continuous operation in the compact 1.5 IN high Mini PC chassis.

Which display cables and monitors must I already own to use the 1x DP and 3x mDP outputs on the T400 4GB GDDR6 card?

You need monitors with DisplayPort or mini-DisplayPort inputs and matching cables; the T400 provides one full-size DP and three mDP ports for up to four screens.

Will my existing USB 3.2 Type-A peripherals work with the single USB 3.2 Type-C port on this Mini PC?

The front USB 3.2 Type-C port accepts Type-A devices via an adapter or hub; legacy keyboards, mice and drives remain fully compatible.
