Business-ready micro desktop

The Dell OptiPlex 3090 Micro is a compact business desktop built around a 10th-generation Intel Core i5-10500T processor with six cores reaching 3.8 GHz under turbo. It ships with 32 GB of DDR4 memory and a 256 GB SSD, running Windows 10 Pro out of the box for immediate deployment in office environments.

Connectivity within the tiny footprint

The system provides four USB 3.2 Gen 1 Type-A ports and two DisplayPort outputs for dual-monitor setups, plus an RJ-45 Ethernet jack for wired networking. Optional knock-out slots allow a serial, PS/2, VGA, DisplayPort 1.4 or HDMI 2.0 port to be added, but no wireless card is installed, so Wi-Fi and Bluetooth require a separate adapter.

Memory headroom and storage limits

The 32 GB DDR4 configuration handles heavy multitasking and large datasets without paging, while the 256 GB SSD offers fast boot and application loads for typical business workloads. Users needing extensive local media libraries, virtual-machine images or large project archives will outgrow the drive and should plan for external or network-attached storage.

Questions about this item

Should I pick the 32 GB DDR4 configuration or is a smaller kit enough?

The unit ships with 32 GB DDR4 already installed, so no smaller kit is needed.

What does the 3.8 GHz turbo figure mean for everyday workloads?

The Core i5-10500T can boost its six cores to 3.8 GHz when thermal headroom allows, speeding up bursty tasks such as spreadsheet recalculations or application launches.

Which display outputs does the micro desktop actually provide?

Two DisplayPort connectors are built in, and an optional port can be configured for HDMI 2.0, VGA or an extra DisplayPort 1.4.
