Ultra-small desktop for office and study

The DELL OptiPlex 790 USFF is a compact desktop computer built around a 2nd Gen Intel Quad Core i5-2400 processor running at 3.10 GHz. It arrives with Windows 10 Professional 64-bit installed and includes a USB keyboard and mouse, so it is ready for everyday productivity or student workloads straight away. The ultra-small form factor keeps desk clutter to a minimum.

8 GB DDR3 and 128 GB SSD headroom

8 GB of DDR3 memory handles typical multitasking such as web browsing, document editing and video playback without strain. The 128 GB solid-state drive provides fast boot and application launch times, though its capacity fills quickly with large media libraries or modern game installations. A 16X DVD±RW drive adds optical media read and write capability for legacy software or backups.

Integrated graphics and wired connectivity

Intel HD Graphics 2000 drives display output using system memory, which suits office applications and video streaming but not 3D-intensive tasks. Gigabit Ethernet supplies reliable wired network access, while multiple USB 2.0 ports, plus legacy PCI, PCI Express x16, parallel and serial ports, allow peripheral expansion within the limits of the ultra-small chassis. No monitor is included.

Questions about this item

Will the Intel HD Graphics 2000 output to my older VGA monitor without an adapter?

The OptiPlex 790 USFF includes VGA and DisplayPort outputs driven by the Intel HD Graphics 2000, so a legacy VGA display connects directly.

How can I verify the 8 GB DDR3 memory is running in dual-channel mode after installation?

Open Task Manager, select the Performance tab, choose Memory and confirm two slots are used with matching 4 GB modules showing 64-bit operation.

Does the box contain a Wi-Fi card or must I purchase a USB 2.0 wireless adapter separately?

The system ships with a wired Gigabit Ethernet port only; wireless capability requires a separate USB 2.0 adapter or internal PCIe card.
