This small form factor desktop PC is packed with up to Intel vPro® Enterprise with 12th Gen Intel® Core™ i9 processors for real-world, business-class performance. Plus, with an optional AMD Radeon RX6400, you can power through hi-res renderings, video editing, and VR/AR content with ease. Additionally, ICE 5.0 Cooling (Intelligent Cooling Engine) ensures your ThinkCentre maintains temperatures at an optimal level for high-performance computing while carefully controlling power consumption.

Built-in protection

The ThinkCentre M90s Gen 3 has Lenovo ThinkShield, end-to-end hardware and software solutions to protect your data—and your business.  The Trusted Platform Module (TPM) 2.0 chip protects sensitive information while passwords are encrypted, and BIOS-based Smart USB protection prevents unauthorized system access. This desktop PC can even self-heal if it becomes corrupted and has several physical security options to thwart theft.


Flexible & expandable

With the ThinkCentre M90s Gen 3, you can connect to legacy peripherals (up to four monitors) and have the option to tap into the latest WiFi 6E* connectivity. You can also opt for dual solid-state drives (SSD) storage for improved responsiveness and power consumption, as well as faster boot ups and application launches. Plus, with toolless access design, optional Smart Cable, there are ample ports and expansion slots to meet your ever-changing IT needs.

*WiFi 6E requires Windows 11 Pro. Operation is dependent on the support of the operating system, routers/APs/gateways that support WiFi 6E, along with the regional regulatory certifications and spectrum allocation.
