Ultra-small desktop for everyday tasks

The Dell OptiPlex 790 USFF packs a 2nd generation Intel quad-core i5-2400 running at 3.10 GHz, 4 GB of DDR3 memory and a 500 GB hard drive into a compact black and silver chassis. Windows 10 Professional 64-bit is pre-installed and a USB keyboard plus mouse are included, so the system is ready for immediate use in a home office or classroom.

Suits general office work, not heavy workloads

This unit handles web browsing, document editing and video playback comfortably, but the integrated Intel HD Graphics 2000 and modest memory capacity limit 3D rendering, modern gaming or large dataset processing. Buyers who need discrete graphics performance, more than 4 GB of RAM or faster solid-state storage should look at a different configuration.

DDR3 memory defines upgrade options

The motherboard accepts only DDR3 modules, so any memory expansion must use that generation; other DDR types will not fit. Two USB 2.0 ports, Gigabit Ethernet, a 16X DVD±RW drive and legacy PCI plus PCI Express x16 slots provide connectivity for peripherals and internal add-in cards.

Questions about this item

Will my existing DDR3 memory modules work alongside the installed 4 GB?

The system uses DDR3 memory; any added modules must match that type and the motherboard's maximum supported capacity.

How can I verify the Intel HD Graphics 2000 is active after setup?

Open Device Manager in Windows 10 Pro and confirm Intel HD Graphics 2000 appears under Display adapters with no error icon.

Does the box include a monitor or must I supply my own?

A USB keyboard and USB mouse are included; a monitor is not included and must be provided separately.
