Dell OptiPlex 3090 Mini PC

The Dell OptiPlex 3090 is a compact desktop computer built around a 10th Generation Intel Core i5-10500T processor. It ships with 16 GB of DDR3 memory and a 500 GB SSD running Windows 11 Pro. The small form factor suits offices or homes where desk space is limited.

Suits everyday office and home users

This system handles web browsing, email, video calls and document work comfortably. Buyers who want more storage than 500 GB or who need higher memory bandwidth than DDR3 provides should look at other configurations. The two memory slots allow expansion up to 64 GB if required.

500 GB SSD and 16 GB DDR3 headroom

The solid-state drive offers fast boot and application load times for a typical working set of files and programs. Memory headroom exists through the second slot for upgrades to 64 GB total. Demanding workloads such as large media editing or virtualisation will exceed the installed capacity.

Questions about this item

What monitor connections do I need for the OptiPlex 3090 Mini PC to work?

Connect a display using the HDMI or DisplayPort outputs on the rear of the unit; the system has no built-in screen.

Will my existing DDR3 modules work alongside the installed 16 GB stick in the two memory slots?

Yes, the board accepts DDR3 up to 64 GB total across both slots, so additional DDR3 modules are compatible.

How can I confirm the 500 GB SSD is recognised and set as the boot drive after setup?

Open Settings, go to System then Storage, and verify the 500 GB drive appears with Windows installed.
