Business desktop with 120 GB SSD

The Dell OptiPlex 790 is a compact desktop computer built around an Intel Core i5-2400 quad-core processor running at 3.10 GHz. It ships with 8 GB of DDR3 memory and a 120 GB solid-state drive for the operating system and core applications. Windows 10 Home 64-bit comes pre-installed, and a USB WiFi dongle provides IEEE 802.11n wireless connectivity. This configuration targets students, home-office users and small businesses needing a ready-to-run system for everyday productivity tasks.

Sustained office workloads with integrated graphics

The i5-2400 maintains its 3.10 GHz base clock across four cores without turbo boost, so performance stays consistent during long document editing, web browsing or video playback sessions. Intel HD Graphics 2000 drives a single VGA output for basic display needs; it handles 2D business applications and video decode but is not suited for 3D rendering or modern gaming. The 120 GB SSD keeps boot times and application launches responsive, while the DVD-ROM drive covers legacy media access.

Replaces older hard-drive desktops for snappier

Moving from a traditional mechanical hard drive to the 120 GB SSD delivers the most noticeable improvement in system responsiveness and boot speed. The 8 GB DDR3 allocation is adequate for typical multitasking with office suites and browser tabs. Buyers who need more storage capacity, discrete graphics performance, additional display outputs or newer connectivity standards should consider a different platform, as this unit relies on integrated graphics, VGA-only video and the supplied USB wireless adapter.

Questions about this item

How much power does the Intel Core i5-2400 draw under continuous load?

The processor runs at 3.1 GHz across four cores; the system includes a 120 GB SSD and integrated Intel HD Graphics 2000, which together keep overall draw modest for typical office workloads.

Which peripherals and cables are required to start using this desktop?

A monitor with a VGA input, a keyboard and a mouse are essential; the box already supplies a USB keyboard, USB mouse and a USB WiFi dongle, so only the display cable needs to be provided.

Will my existing DDR3 memory modules work if I want to expand the 8 GB already installed?

The motherboard uses DDR3 slots, so any standard DDR3 DIMM that matches the board's maximum capacity and speed can be added alongside the factory memory.
