Mini workstation for professional workflows

This Lenovo ThinkStation Mini desktop combines a 14th Gen i9-14900 processor with 24 cores and 32 threads, an NVIDIA T400 4GB GDDR6 graphics card, 8GB DDR5 memory and a 1TB PCIe NVMe SSD. It ships with Windows 11 Pro and includes a USB keyboard and mouse for immediate deployment.

300W power supply limits expansion headroom

The 300W PSU supports the factory configuration of the i9-14900 and T400 but leaves minimal overhead for additional internal components or higher-power GPU upgrades. Display outputs comprise HDMI, one DisplayPort and three mini DisplayPort connectors driven through the PCI Express x16 graphics interface.

8GB DDR5 suits light multitasking.

The single 8GB DDR5 SO-DIMM handles office suites, browser workloads and basic CAD viewports, yet memory-intensive rendering or large dataset analysis will require a capacity increase. The 1TB NVMe SSD accommodates the operating system, applications and current project files, while archival storage demands external or network solutions.

Questions about this item

Should I choose the 8GB DDR5 configuration or look for a larger memory option?

The system ships with 8GB DDR5 SO-DIMM; the mini form factor has limited slots so adding more later may require replacing the module.

What does the i9-14900 2.00GHz up to 5.8GHz 24-core 32-thread processor deliver in daily workloads?

The 14th Gen i9-14900 runs at 2.00GHz base and can boost to 5.8GHz across 24 cores and 32 threads, giving strong multi-threaded performance for rendering and compile jobs.

How does the PCI Express x16 interface affect the NVIDIA T400 4GB GDDR6 graphics in this mini chassis?

The T400 connects via PCI Express x16 but the 300W power supply caps total system draw, so the GPU runs at its rated clocks within that power envelope.
