Business all-in-one with 23.8 inch display

The ThinkCentre M90a Gen 6 integrates a 23.8 inch screen with an Intel Core Ultra 5 225 processor running at up to 4.9 GHz. It ships with 16 GB of memory and a 512 GB SSD for everyday office workloads. Windows 11 Pro is pre-installed for immediate deployment.

Sustained workload behaviour

The 180 watt power supply supports continuous operation during long business hours without thermal throttling. Integrated graphics handle standard productivity applications and video playback across the 23.8 inch panel. The system maintains stable performance for typical multi-tasking scenarios.

Thermals noise and power

Fan noise remains low in normal office use thanks to the efficient thermal design of the all-in-one chassis. Power draw scales with the 180 watt supply capacity under typical loads. The UltraFlex V stand allows ergonomic positioning while keeping airflow paths clear.

Questions about this item

How much heat does the 180-watt power supply add to a room during all-day use?

The system draws up to 180 watts, so sustained load releases roughly that much heat into the space.

What peripherals must I already own to operate this all-in-one?

Only a power cable is required; the box includes a USB Calliope mouse and the 23.8-inch display is built in.

Can I keep using my older VESA-mounted monitor arm with this 23.8-inch unit?

Yes, the chassis supports standard VESA mounting so existing arms or brackets will fit.
