Ultra-small desktop with Core Ultra 9 285

This Lenovo ThinkCentre M90q Gen 6 is a new tiny-form-factor desktop that ships with Windows 11 Pro. It is built around the Intel Core Ultra 9 285 processor and comes with 64 GB of DDR5 5600 memory and a 1 TB NVMe 4.0 x4 SSD. The 230 W power supply is integrated into the compact chassis. It suits buyers who need high CPU performance in the smallest possible footprint.

Suits space-constrained offices.

The system fits on a shelf, behind a monitor or in a VESA mount, making it ideal for reception desks, kiosks or dense deployments. Integrated Intel Graphics handles office applications, video conferencing and multi-monitor productivity. Buyers who need a discrete GPU, internal drive bays or PCIe add-in cards should look at a larger form factor because the tiny chassis does not accommodate them.

64 GB DDR5 5600 soldered capacity

The 64 GB DDR5 5600 memory is the deciding specification: it is the maximum the platform supports and it is not user-upgradeable. If your workloads require more than 64 GB of RAM, this model cannot meet that need. For workloads that fit within 64 GB, the high-speed DDR5 and 1 TB NVMe 4.0 x4 SSD deliver responsive performance in a 2025 tiny desktop.

Questions about this item

What physical dimensions does the Tiny form factor require for mounting?

The Tiny chassis uses Lenovo's standard VESA mount pattern so it can attach to the back of a compatible monitor or a dedicated bracket.

Which step is often missed when installing the 230 W power adapter?

Connect the adapter to the barrel jack on the rear before plugging the cord into the wall outlet to avoid a loose connection.

When will the 1 TB NVMe 4.0 x4 SSD need replacement?

The drive is rated for typical enterprise write endurance; plan a refresh after several years of heavy workloads or when SMART tools report wear.
