Compact business desktop for office workflows

The Dell OptiPlex 3090 Mini PC pairs a 10th Generation Intel Core i5-10500T processor with 16 GB of DDR3 memory and a 500 GB SATA SSD. It ships with Windows 11 Pro, a 24-inch LCD monitor, wired keyboard and mouse, plus Wi-Fi and Bluetooth connectivity. The small black chassis weighs 2.82 kg and fits tight workspaces.

Steady throughput on long tasks

The six-core i5-10500T maintains consistent clock speeds during extended document editing, video calls and browser sessions without thermal throttling. Sixteen gigabytes of DDR3 RAM keeps multiple business applications responsive over an eight-hour day. The SATA SSD delivers sustained read performance for large file opens and background updates.

Quiet operation and modest power draw

In typical office use the system runs near-silent with fan noise barely audible at desk distance. Power consumption stays low during idle and light productivity workloads, reducing electricity cost for fleets. The compact form factor exhausts heat efficiently without requiring extra case airflow.

Questions about this item

How loud and hot does the OptiPlex 3090 Mini PC get when it runs all day?

What must I already own to use the included 24" monitor, wired keyboard and mouse?

The monitor connects via its video cable to the Mini PC, while the keyboard and mouse plug into USB ports; no extra adapters or docks are required.

Will the DDR3 memory and SATA SSD work with older peripherals I keep?
