Compact desktop for everyday work

The Dell OptiPlex 3090 Mini PC is a small-form-factor desktop built around an Intel Core i5-10500T processor. It ships with 16 GB of DDR3 memory in a single module and a 1 TB SATA solid-state drive. Windows 11 Pro is pre-installed, and the unit includes Wi-Fi and Bluetooth connectivity plus wired peripherals. Its 2020 release date and 2.82 kg weight suit office or home desks where space is limited.

Fits general office and study use.

This system suits users who need a ready-to-run Windows machine for web browsing, document editing, video calls and media streaming. The two memory slots support up to 64 GB total capacity, so buyers who want more storage or extra memory headroom can expand later. It is not intended for workloads that demand discrete graphics acceleration, high-core-count processing or specialised expansion cards beyond the mini chassis limits.

16 GB DDR3 memory configuration decides fit

The installed memory is a single 16 GB DDR3 module, leaving one slot free for an identical DDR3 stick to reach the 64 GB maximum. Buyers must match the DDR3 specification exactly; other memory generations are physically and electrically incompatible with this platform. Confirming this memory type before purchase ensures the system will accept any planned upgrade.

Questions about this item

How loud does the 3090 Mini PC get when the Core i5-10500T runs all day?

The Mini PC form factor uses a compact cooling system designed for the 10th Generation Intel Core i5; under sustained loads the fan ramps up but remains at office-acceptable levels.

The listing shows a wired gaming keyboard, USB mouse and RGB speakers — do I need to supply any other peripheral for first boot?

No, the bundle includes a wired keyboard, USB mouse and RGB speakers; just add a display with HDMI or DisplayPort input and a power outlet.

I still use SATA hard drives — can the 3090 Mini PC accommodate one alongside the 1 TB SSD?

The chassis has a SATA interface and space for a 2.5-inch drive, so an existing SATA HDD can be installed as secondary storage.
