Lenovo ThinkCentre M90s Gen 6 desktop PC Intel Core Ultra 5 225 16GB 512GB SSD

Compact desktop for multi-monitor productivity

The Lenovo ThinkCentre M90s Gen 6 is a small-form-factor PC built around the Intel Core Ultra 5 225 processor. It ships with 16 GB of DDR5 memory and a 512 GB M.2 2280 PCIe Gen4 TLC Opal solid-state drive. Windows 11 Pro 64 is pre-installed. The system supports up to four independent monitors from integrated Intel graphics, making it suited for office and trading desks that need multiple displays.

Simple SFF access with limited internal space

The Raven Black chassis opens without tools for memory and drive upgrades. Two UDIMM slots are populated with 8 GB modules running at 4400 MT/s, so adding capacity means replacing the existing sticks. Only one M.2 2280 slot is occupied; a second M.2 slot and a 2.5-inch bay are available for extra storage. The 1.00 lb weight reflects the bare chassis; the packed unit is heavier. No discrete graphics card can be fitted due to the slim profile and proprietary power supply.

Verify display outputs

Check that your monitors match the video ports on the rear panel — typically DisplayPort and HDMI — to drive four screens without adapters. Ensure the included power supply delivers enough headroom for any additional drives you plan to install. The processor uses E-cores up to 4.40 GHz and P-cores up to 4.90 GHz, so sustained workloads will draw more power than idle office use. Confirm the operating system language and regional settings meet your deployment requirements.
