Dell OptiPlex 790 Mini Tower desktop

This Dell OptiPlex 790 Mini Tower desktop computer ships new with Windows 10 Pro 64-bit installed. It uses an Intel 2nd Gen Core i7-2600 quad-core processor running at 3.40 GHz with Turbo Boost up to 3.90 GHz. The system includes 8 GB of DDR3 memory and a dual-drive layout with a 128 GB SSD plus a 1 TB hard drive.

Suited for office tasks and legacy software

The 8 GB DDR3 configuration and integrated Intel HD Graphics 2000 handle everyday productivity, web browsing and older applications. Buyers who need more memory for modern multitasking or a dedicated graphics card for current games should look elsewhere. The 265 W power supply and Mini Tower chassis limit internal expansion options.

Sustained workload behaviour

Under continuous load the quad-core CPU can maintain elevated frequencies within the 265 W power envelope. The SSD accelerates boot and application launch while the 1 TB hard drive provides capacity for long-term data storage. Thermal performance is managed by the Mini Tower airflow design for typical office duty cycles.

Questions about this item

What monitor connection do I need for the Intel HD Graphics 2000 output?

The integrated Intel HD Graphics 2000 provides video output through the motherboard ports; connect a compatible monitor cable to the rear display port to use the built-in graphics.

Can I keep using my existing DDR3 memory modules alongside the installed 8GB?

The system uses 240-pin DDR3 DIMM slots; additional modules must match the DDR3 type and 240-pin form factor to work with the installed 8GB.

How can I verify the 128GB SSD is the active boot drive after setup?

Open Windows 10 Pro storage settings or BIOS boot order to confirm the 128GB solid state drive is listed as the primary boot device.
