Engineered for the modern workplace

The stylish ThinkCentre M90a Pro Gen 3 AIO is full of enterprise-grade level power and speed. Fueled by up to 12th Gen Intel® Core™ i9 with Intel vPro® platform and optional NVIDIA® graphics, this all-in-one desktop PC gives you high performance whenever you need it. It also comes with the convenience of a phone-docking bar and a clutter-free cord management base.

As flexible as you need it to be

With its smarter, sleek, and secure design, the ThinkCentre M90a Pro Gen 3 AIO is sure to catch the eye. Its stunning 2K display is mounted on a full-function stand with adaptable tilt, lift, and new this year, pivot and swivel (LTPS), along with a tiltable camera, an industry first. There’s also option of an UltraFlex Stand for those who seek greater flexibility in today’s modern workspace.

Look forward to every meeting

With the optional conference call base, virtual meetings run more seamlessly. Quad-array far-field microphones, with 360-degree pick-up, use AI noise-suppressing technology to cut both locally and remote annoying background sound a. As well as four Harman® speakers, super-fast USB-C connectivity brings even more clarity and richness to your meetings, while a single click fires up Microsoft Teams. The 20-degree tilt camera ensures you’re always in the frame while the Thinkshutter guarantees your physical privacy.

Security that’s always got your back

With the Intel vPro® platform, this PC’s security starts at the chip. You also have the option of human presence detection with a walkaway sleep mode for data privacy and to enhance energy efficiency. Plus, there’s ThinkShield—end-to-end security, combining industry-leading hardware and software, such as zero touch logins via the IR camera. Another safeguard is the BIOS-based Smart USB Protection that allows safe functionality for devices such as a keyboard and mouse while blocking connectivity from unauthorized devices.

Built to last

As well as our own rigorous in-house tests, the ThinkCentre M90a Pro Gen 3 all-in-one is measured against 12 US Mil-spec requirements, including more than 200 quality checks to ensure it can run in extreme conditions. They cover harsh variables like Arctic wilderness and desert dust storms, including tests for temperature, pressure, humidity, vibration, and more.

Cooler, quieter, smarter

Thanks to our Intelligent Cooling Engine (ICE) 4.0, the ThinkCentre M90a Pro Gen 3 all-in-one has different power modes based on your computing needs. Boost the power by up to 15%, lower normal system noise by three decibels, or go for maximum cooling. This very modern PC also has optional smart human presence detection that knows when you’re away, enabling a new level of security and energy efficiency.
