Desktop PC for home and student use

The Dell OptiPlex 390 is a desktop computer built for everyday home and student tasks. It runs on an Intel 2nd Gen i3-2100 processor at 3.10GHz with 8 GB of DDR3 RAM. A 3.5" 1 TB hard drive stores the operating system and files. Windows 10 Home 64-Bit comes pre-installed.

Sustained load behaviour

The dual-core processor and integrated Intel HD Graphics 2000 handle light multitasking such as document editing and web browsing. Under heavier continuous loads the system will slow as the mechanical drive and limited memory bandwidth become bottlenecks. The compact desktop chassis relies on passive airflow, so extended high utilisation may cause thermal throttling.

Installation and common issues

The unit arrives with a USB keyboard and mouse so setup only requires a display and power. VGA and HDMI video outputs are available for monitor connection. The 240-pin DDR3 slots allow memory upgrades if needed. Buyers who need faster boot times or quieter operation should note the spinning hard drive and lack of solid-state storage.

Questions about this item

How much heat and noise should I expect from the Intel Core i3-2100 running all day?

The dual-core 3.10 GHz processor and integrated Intel HD Graphics 2000 draw modest power, so the system fan stays quiet during typical office tasks and the chassis remains cool to the touch.

Do I need to supply my own display and cables to use the VGA and HDMI outputs?

No monitor is included; you will need a display with a VGA or HDMI input and the matching cable to connect to either video port on the back panel.

Will my existing DDR3 memory modules work if I want to expand beyond the installed 8 GB?

The board uses 240-pin DDR3 DIMM slots, so any compatible DDR3 modules you already own can be added up to the motherboard's maximum capacity.
