Tiny business desktop

The Dell OptiPlex 3090 Micro is a 2021 tiny-form-factor desktop built for office environments. It ships new with Windows 10 Pro, a six-core Intel Core i5-10500T processor and 64 GB of DDR4 memory. The 1 TB SSD provides the primary storage. No wireless card is fitted.

Suited to managed fleets, not wireless-first users

This configuration suits IT teams deploying standardised Windows 10 workstations that rely on wired Ethernet and dual DisplayPort monitors. The 64 GB memory ceiling supports heavy multitasking and virtual machines. Buyers who need built-in Wi-Fi or Bluetooth should look elsewhere, as the chassis only provides knock-out slots for an optional antenna.

64 GB DDR4 and 1 TB SSD headroom

The 64 GB DDR4 capacity handles large datasets, multiple browser profiles and local development containers without paging. The 1 TB SSD holds the operating system, applications and a substantial working file library. Storage expansion is limited to the single drive bay, so users anticipating multi-terabyte media libraries will reach the physical limit quickly.

Questions about this item

Does the i5-10500T require a separate graphics card, or does it use the integrated graphics chip mentioned in the specifications?

The processor includes an integrated graphics chip, so a separate graphics card is not required for display output.

Will the two DisplayPort outputs support monitors that only have HDMI inputs?

The system provides two DisplayPort connections; monitors with HDMI inputs will need a DisplayPort-to-HDMI adapter or cable.

After connecting power and a monitor, what indicates the OptiPlex 3090 Micro is booting correctly?

Press the power button; the LED should light and the Windows 10 Pro start-up sequence will appear on the connected display.
