Ultra-compact business desktop

The Dell OptiPlex 7090 Micro desktop PC measures 36 mm wide, 183 mm deep and 178.5 mm high, weighing from 1.30 kg. An Intel Core i7-10700T eight-core processor runs at 2.0 GHz with a 4.5 GHz turbo boost. 64 GB of DDR4 memory and a 256 GB SSD come pre-installed with Windows 11 Pro for immediate deployment.

Build integration

The tiny chassis sits on a desk, behind a monitor or in a rack shelf without needing a full tower case. Two DisplayPort 1.4 outputs and an HDMI 2.0 port drive multiple displays directly from the integrated graphics chip. USB 3.2 Gen2x2 Type-C, USB 3.2 Gen2 Type-A and USB 3.2 Gen1 Type-A ports handle peripherals and PowerShare charging. RJ-45 and Wi-Fi give network flexibility.

Included accessories

A wired keyboard and mouse are bundled so the system is ready to work out of the box. Windows 11 Pro is preloaded, removing the need for a separate licence or installation media. The cable clip and thumbscrew simplify cable routing and chassis access. An optional VGA port and serial/PS2 ports support legacy equipment if required.

Questions about this item

Does the 4.5 GHz turbo on the i7-10700T hold under continuous load in the 36 mm micro chassis?

The 10th Gen eight-core CPU reaches 4.5 GHz turbo, but the tiny 1.4" wide case limits sustained clocks; expect frequencies to settle lower once the single blower fan saturates.

How loud does the micro desktop get when the i7-10700T runs all day at full tilt?

The compact 1.30 kg chassis relies on one internal blower; under prolonged heavy load the fan spins audibly higher, producing a noticeable but not extreme airflow noise in a quiet room.

What display cables or adapters do I need to connect two monitors to the integrated graphics?

The rear provides two DisplayPort 1.4 outputs and one HDMI 2.0 port; use native DP-to-DP or DP-to-HDMI cables for the two displays you plan to attach.
