Lenovo ThinkStation Mini PC i9-14900 T400 4GB 8GB DDR5 1TB NVMe Windows 11 Home 300W

Compact workstation for professional workloads

This Lenovo ThinkStation Mini PC pairs a 14th Gen Intel Core i9-14900 processor with NVIDIA T400 4GB GDDR6 graphics and 8GB DDR5 memory. The 24-core, 32-thread CPU reaches 5.8GHz for demanding compute tasks, while the discrete GPU supports multi-display output via HDMI, DisplayPort and three mini DisplayPort connectors. It ships with Windows 11 Home on a 1TB PCIe NVMe SSD.

8GB DDR5 and 1TB NVMe capacity with discrete 4GB GPU

The 8GB DDR5 SO-DIMM handles mainstream office applications and light content creation, but memory-intensive workloads such as large dataset analysis or heavy virtualisation will exhaust this capacity. The 1TB NVMe drive provides fast boot and project storage, yet high-resolution video libraries or extensive CAD archives may require external expansion. The T400 4GB GDDR6 frame buffer suits 2D design and multi-monitor productivity, not modern 3D rendering or GPU compute.

Mini PC form factor limits upgrade paths

The 300W power supply and compact 7 x 7.25 x 1.5 inch chassis restrict graphics upgrades to low-profile, low-power cards and leave no room for additional internal storage drives. WiFi 6 and Bluetooth 5.3 handle wireless peripherals, while the single RJ-45 port provides wired networking. Buyers needing multiple high-power GPUs, large memory arrays beyond two SO-DIMM slots, or extensive internal drive bays should consider a full-size workstation tower.
