Ready-to-use desktop for home and student tasks

This DELL OptiPlex 790 Mini Tower arrives with Windows 10 Pro installed and a USB keyboard and mouse included. A quad-core Intel i5-2400 processor running at 3.10 GHz works with 16 GB of DDR3 memory. The 256 GB 2.5-inch SSD provides solid-state storage for the operating system and everyday files.

Simple setup with limited internal expansion

All four DIMM slots are populated with 4 GB modules, so adding more memory means replacing the existing sticks. The mini-tower case uses standard 240-pin DDR3 desktop RAM and offers a 2.5-inch drive bay already occupied by the SSD. A DVD±RW drive and a USB WiFi adapter are fitted, while integrated Intel HD Graphics 2000 handles video output.

Suits everyday office and study use.

Buyers who need a complete system for web browsing, document editing and video playback will find the specification matches those needs. Users who require a dedicated graphics card, additional internal storage bays, or memory beyond the 16 GB maximum supported by the Intel Q67 chipset should consider a different platform.

Questions about this item

How can I confirm the Intel HD Graphics 2000 is active after Windows 10 Pro boots?

Open Device Manager and verify Intel HD Graphics 2000 appears under Display adapters without a warning icon.

What comes in the box and what must I source separately?

The Mini Tower, 16 GB DDR3 installed as 4 GB x 4 across four DIMM 240-pin slots, 256 GB 2.5" SSD, DVD±RW drive, USB keyboard, USB mouse, WiFi USB adapter, Windows 10 Pro with CoA and restore media. No monitor or cables are included.

Which memory capacity should I choose for this OptiPlex 790?

The board has four DIMM 240-pin slots and a 16 GB DDR3 ceiling; this unit already populates every slot with 4 GB modules, so no further DDR3 upgrades are possible.
