Ready-to-use desktop with integrated 19" display

This all-in-one system combines the computer and a 19-inch Dell LCD monitor in a single black-and-silver chassis. An Intel quad-core i5-2400 processor running at 3.10 GHz with a 3.4 GHz turbo boost works alongside 8 GB of DDR3 RAM and a 128 GB SSD. Windows 10 Professional 64-bit is pre-installed, and a USB keyboard and mouse are included.

Office and education users needing a compact.

The integrated screen and small footprint suit desk-bound tasks such as document work, web browsing and video calls where a separate tower and monitor would take more space. Gigabit Ethernet provides wired network connectivity and the DVD-RW drive reads legacy media. Buyers who require a larger display, discrete graphics or internal expansion beyond the available PCI and PCI Express x16 slots should consider a traditional tower system.

128 GB SSD for operating system

The solid-state drive delivers fast boot times and responsive application launches for everyday workloads. With 8 GB of DDR3 memory the system handles typical multitasking such as several browser tabs and office programs simultaneously. Storage capacity is limited to 128 GB, so users with large media libraries or extensive local databases will need external drives or cloud storage to supplement the internal volume.

Questions about this item

Will my existing DDR3 memory modules fit the 240-pin slots inside the OptiPlex 790 USFF?

The system uses 240-pin DDR3 DIMM slots, so any standard DDR3 module with that pin count will fit physically.

Can I keep using my older USB 2.0 keyboard and mouse with the USB ports on this all-in-one?

Yes, the multiple USB 2.0 ports accept legacy USB 2.0 input devices without adapters.

How can I confirm the integrated Intel HD Graphics 200 is active after Windows 10 Pro boots?

Open Device Manager, expand Display adapters, and verify Intel HD Graphics 200 appears without a warning icon.
