Compact workstation for multi-threaded tasks

The Lenovo ThinkStation Mini desktop pairs a 14th Gen i9-14900 processor with 24 cores and 32 threads with an NVIDIA T400 GPU that adds 4GB of GDDR6 memory. It ships with 8GB of DDR5 SO-DIMM memory and a 2TB PCIe NVMe SSD, all driven by a 300W power supply inside a 7 by 7.25 by 1.5 inch chassis that weighs 3.1lb. Windows 11 Home is pre-installed.

Dual graphics and connectivity bundle

The T400 card supplies one full-size DisplayPort and three mini-DisplayPort outputs alongside the system HDMI port, enabling up to four simultaneous displays without adapters. A USB 3.2 Type-C port and a headphone/microphone combo jack sit on the front, while WiFi 6 and Bluetooth 5.3 handle wireless links and an RJ-45 jack provides wired networking. A USB keyboard and mouse are included in the box.

Power and memory ceiling limits

The 300W internal supply caps total system draw, so the i9-14900 cannot sustain its 5.8GHz turbo across all 24 cores indefinitely under heavy compute loads. Only a single SO-DIMM slot is populated with 8GB of DDR5, leaving no room for expansion without replacing the module. The mini form factor also prevents the addition of a second graphics card or extra internal storage bays.

Spurningar um þessa vöru

Will the 8 GB DDR5 SO-DIMM need upgrading for heavier workloads?

The system ships with a single 8 GB DDR5 SO-DIMM; adding a second module enables dual-channel bandwidth and raises total capacity for memory-intensive tasks.

What limits the i9-14900 during prolonged all-core loads?

The 300 W power supply and compact 1.5-inch chassis constrain sustained turbo clocks, so the 24-core CPU will throttle before thermal limits are reached.

How loud and hot does the mini PC get when running all day?

The small 7 × 7.25 × 1.5 in case and 300 W PSU mean fan speeds rise noticeably under continuous load, producing audible airflow and warm exhaust.
