Compact workstation with 14th Gen i9-14900

This Lenovo ThinkStation Mini desktop pairs a 14th Gen i9-14900 processor with 24 cores and 32 threads up to 5.8 GHz with an NVIDIA T400 4 GB GDDR6 card. It ships with 8 GB DDR5 memory and a 4 TB PCIe NVMe SSD. Windows 11 Home is pre-installed.

Suited for multi-threaded workloads in a small

The 24-core CPU handles rendering, compilation and data analysis while the T400 drives up to four displays via one full-size DisplayPort, three mini-DisplayPort outputs and HDMI. Buyers who need more than 8 GB of memory or a higher-wattage GPU should consider other configurations.

300 W power supply limits GPU upgrade options

The internal 300 W unit powers the i9-14900 and T400 combination as delivered. Adding a graphics card that draws significantly more power would exceed the supply capacity, so the installed T400 defines the practical graphics ceiling for this chassis.

Questions about this item

How loud and hot does the 300 W power supply run when the i9‑14900 hits its 5.8 GHz boost all day?

The 300 W PSU powers the 24‑core i9‑14900 and T400 graphics; the mini chassis uses a single internal fan that spins up under sustained load, so expect audible airflow and warm exhaust after hours of full‑speed work.

What display cables do I need to use the HDMI, DisplayPort and three mini‑DisplayPort outputs on the T400?

The T400 provides one HDMI, one full‑size DisplayPort and three mini‑DisplayPort connectors; you must supply matching cables or adapters for each monitor you attach.

Can the 7 × 7.25 × 1.5 in mini case sit beside a legacy PCI‑card expansion box without overheating?

The compact 3.1 lb enclosure exhausts heat through its rear vents; keeping a few centimetres of clearance from adjacent gear lets the 300 W supply dissipate heat normally.
