Compact workstation with i9-14900 and T400

This Lenovo ThinkStation mini desktop pairs a 14th Gen Intel Core i9-14900 processor with 24 cores and 32 threads with an NVIDIA T400 4GB GDDR6 graphics card. The system ships with 16GB DDR5 SO-DIMM memory and a 512GB PCIe NVMe SSD. Windows 11 Pro is pre-installed for professional workloads.

Port mix and input bundle

The chassis provides HDMI, one full-size DisplayPort and three mini DisplayPort outputs for multi-monitor arrays. A USB 3.2 Type-C port and a headphone/microphone combo jack sit alongside the wired RJ-45 Ethernet, WiFi 6 and Bluetooth 5.3 radios. A USB keyboard and mouse are included in the box.

300 W power envelope and mini footprint

The integrated 300W power supply caps total system draw, limiting future GPU upgrades to cards that fit within the same thermal budget. The 7 by 7.25 by 1.5 inch case leaves no room for full-height expansion cards or additional internal storage bays. Buyers who need more graphics memory or a second discrete card should consider a larger chassis.

Questions about this item

How long before the 300W PSU or the 16GB DDR5 SODIMM need replacement?

The 300W PSU is a standard desktop unit rated for continuous operation; the 16GB DDR5 SODIMM has no moving parts and typically lasts the life of the system unless a fault occurs.

What thermal or power limit appears first when the i9-14900 runs at 5.8GHz on all 24 cores inside the 1.5in high chassis?

The 300W PSU and the compact 7in x 7.25in x 1.5in enclosure constrain sustained turbo; the CPU will throttle to stay within the power budget and the thermal capacity of the mini chassis.

How loud and hot does the system get when the NVIDIA T400 4GB GDDR6 and i9-14900 run all day?

The small form factor uses a single internal fan; under full load the fan spins up audibly and exhaust air becomes warm, but the 300W PSU limits total heat output to what the chassis can dissipate.
