Dell OptiPlex 790 Mini Tower desktop

This Dell OptiPlex 790 Mini Tower desktop is built around an Intel 2nd Gen i7-2600 quad-core processor running at 3.40 GHz with a 3.90 GHz turbo boost. It ships with 8 GB of DDR3 memory, a 256 GB 2.5-inch solid-state drive and a 2 TB 3.5-inch hard drive. Windows 10 Pro 64-bit is pre-installed and a USB keyboard and mouse are included.

Suits office tasks, study and light media playback

The integrated Intel HD Graphics 2000 and 265 W power supply limit this system to basic productivity, web browsing and video streaming. Buyers who need discrete graphics performance for gaming, 3D work or multi-monitor 4K output should look at a different platform. The Mini Tower case uses a DIMM 240-pin memory layout and provides standard expansion slots for future upgrades.

Sustained load behaviour and thermal limits

Under continuous multi-threaded workloads the quad-core CPU will throttle toward its base frequency once the 265 W power budget and compact Mini Tower cooling are saturated. The SSD handles operating system and application I/O without slowing, while the 2 TB hard drive provides high-capacity archival storage that is unaffected by thermal constraints.

Questions about this item

What type of RAM slots does the OptiPlex 790 motherboard provide for the installed 8 GB DDR3 memory?

The system uses 240-pin DIMM slots for its DDR3 desktop memory.

Can the integrated Intel HD Graphics 2000 drive a legacy VGA monitor without an adapter?

Video output depends on the specific rear-panel ports fitted to this Mini Tower; check the back of the chassis for a blue VGA connector.

How can I verify the 256 GB SSD is recognised as the boot drive after first power-on?

Open Windows Settings, go to System > Storage, and confirm the 256 GB solid-state drive shows the Windows logo and is marked as the boot device.
