Dell OptiPlex 790 Mini Tower

This desktop computer uses a 2nd Generation Intel Core i5-2400 processor running at 3.10 GHz with four cores and four threads. It includes 8 GB of DDR3 memory and a 128 GB 2.5-inch SSD. Windows 10 Pro 64-bit is pre-installed. A DVD±RW drive, USB keyboard and USB mouse are supplied in the box.

Suits everyday office and study tasks

The system handles web browsing, document editing, email and video playback comfortably. Integrated Intel HD Graphics 2000 and the modest 128 GB SSD limit its usefulness for modern gaming, heavy creative workloads or large media libraries. Buyers who need more storage, dedicated graphics or a newer processor architecture should look at something else.

128 GB SSD and 8 GB DDR3 headroom

The solid-state drive provides fast boot and application launch for a core set of programs and files, but fills quickly with games or large projects. Memory can be expanded to 16 GB DDR3 using the available DIMM slots for better multitasking headroom. Beyond that, the platform’s ageing architecture and integrated graphics become the limiting factors.

Questions about this item

Does the i5-2400 processor in this OptiPlex 790 need a separate graphics card to run a display?

No, the i5-2400 includes Intel HD Graphics 2000 so a monitor can be connected directly to the motherboard video ports.

Will my existing DDR3 memory modules work if I add them to the four DIMM slots on this 790 Mini Tower?

Yes, the board accepts standard 240-pin DDR3 DIMMs up to 16 GB total, so compatible modules you already own can be installed alongside the 8 GB fitted.

How can I confirm the 128 GB SSD is recognised and set as the boot drive after first power-on?

Enter the BIOS setup on startup and check the drive list; the 2.5-inch 128 GB solid-state drive should appear as the first boot device.
