Lenovo ThinkStation i9-14900 Mini PC

This compact desktop pairs a 14th Gen Intel Core i9-14900 processor with an NVIDIA T400 4GB GDDR6 graphics card. It targets professionals who need multi-threaded CPU performance and entry-level workstation graphics in a small footprint. The system ships with Windows 11 Home pre-installed.

300W PSU, DDR5 memory, and multi-display outputs

The 300-watt power supply drives the 24-core CPU and discrete GPU within a 7 by 7.25 by 1.5-inch chassis weighing 3.1 pounds. Sixteen gigabytes of DDR5 SO-DIMM memory and a 1TB PCIe NVMe SSD are installed. Video outputs comprise one full-size DisplayPort, three mini DisplayPort connectors, and an HDMI port for up to four simultaneous displays.

PCIe x16 graphics interface and connectivity limits

The NVIDIA T400 connects through a PCI Express x16 interface, capping GPU bandwidth to that generation's throughput. Wireless networking uses WiFi 6 (802.11ax) and Bluetooth 5.3, while wired access relies on a single RJ-45 port. The 300W unit leaves no headroom for higher-power graphics upgrades.
