Compact business desktop

The Dell OptiPlex 3090 Micro is a 2021 tiny-form-factor PC built for office environments. It ships with Windows 10 Pro, 32GB of DDR4 memory and a dual-drive layout of 128GB SSD plus 1TB HDD. The integrated graphics chip handles standard productivity workloads without a discrete card.

Sustained thermal behaviour

The six-core i5-10500T runs at a 2.3GHz base frequency and can reach 3.8GHz with Turbo Boost. Because the chassis measures only 36mm wide, prolonged heavy loads will hit thermal limits faster than larger towers, causing clocks to settle at lower speeds to stay within the enclosure's cooling capacity.

Connectivity and expansion limits

Front and rear I/O provide four USB 3.2 Gen 1 Type-A ports and two DisplayPort outputs, with optional serial, PS/2, VGA, DP 1.4 or HDMI 2.0 knock-outs. No wireless card is fitted, so wired Ethernet via the RJ-45 port is the only network path unless a separate adapter is added. The micro form factor rules out full-height add-in cards.

Questions about this item

Does the 36 mm thin chassis keep the i5-10500T cool and quiet when running all day?

The micro form factor measures 36 mm wide and uses a compact thermal design; under sustained workloads the fan becomes audible but remains a low hum.

What display and network cables must I already have to use this desktop?

Two DisplayPort outputs are built in; an optional HDMI 2.0 or VGA port can be added via the knock-out slot, and a wired RJ-45 Ethernet cable is required because no wireless card is installed.

Will my existing DDR4 memory modules work if I want to expand the 32 GB already installed?

The system uses DDR4 memory; any added modules must match the DDR4 standard already present.
