Lenovo ThinkStation Mini PC i9-14900 16GB DDR5 4TB NVMe T400 4GB Win 11 Home

Compact workstation for professional workloads

This Lenovo ThinkStation Mini PC 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 includes 16GB DDR5 memory and a 4TB PCIe NVMe SSD running Windows 11 Home. It targets professionals who need multi-threaded compute performance and certified drivers in a 7 x 7.25 x 1.5 inch chassis that weighs 3.1lb.

Verify display outputs and peripheral clearance

The unit provides one HDMI port, one full-size DisplayPort and three mini DisplayPort connectors, so confirm your monitors match these interfaces or that you have suitable adapters. Two USB 3.2 Type-C ports and a headphone/microphone combo jack handle accessories, while WiFi 6 and Bluetooth 5.3 cover wireless needs. A wired USB keyboard and mouse are included in the box.

Sustained load within a 300W power envelope

The 300W power supply feeds the CPU, which can reach 5.8GHz boost clocks, and the discrete GPU simultaneously, so extended all-core workloads will operate at the thermal and electrical limits of the compact form factor. Expect clock speeds to settle below peak boost during long renders or simulations as the cooling system balances temperature against the fixed power budget. The 36MB L3 cache helps maintain throughput when frequency scales back.
