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

Compact workstation with 24-core i9-14900

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 8GB of DDR5 memory and an 8TB PCIe NVMe SSD. It ships with Windows 11 Home and offers WiFi 6, Bluetooth 5.3, and wired RJ-45 networking in a 7 by 7.25 by 1.5 inch chassis.

Sustained multi-thread throughput in a 300W envelope

The 300W power supply feeds a CPU rated for a 5.8GHz maximum turbo frequency across 8 performance cores and 16 efficient cores. Under continuous load the mini form factor relies on its integrated thermal design to maintain clocks without the airflow of a full tower. The T400 adds dedicated GDDR6 memory for professional 2D and light 3D workloads while sharing the same power budget.

Display and peripheral connectivity limits

Video output is provided through one full-size DisplayPort, three mini DisplayPort connectors, and one HDMI port, supporting up to four simultaneous displays. A single USB 3.2 Type-C port and a headphone/microphone combo jack handle modern peripherals. The compact layout omits legacy ports, internal drive bays, and expansion slots, so users needing additional GPUs, capture cards, or high-count USB arrays must look elsewhere.
