OptiPlex 790 Mini Tower desktop

The Dell OptiPlex 790 Mini Tower is a new desktop computer built around an Intel 2nd Gen i7-2600 quad-core processor at 3.40 GHz with 8 GB of DDR3 memory. It combines a 512 GB solid-state drive and a 2 TB hard drive for fast boot and ample storage. Windows 10 Pro is installed with a Certificate of Authenticity. A USB keyboard and mouse are included.

Who this suits and who it does not

This system suits home-office users and students who need responsive everyday performance, integrated Intel HD Graphics 2000 output and legacy DVD±RW access. Buyers who require a discrete graphics card for modern gaming or intensive 3D work should look elsewhere. Anyone needing more than 16 GB of DDR3 memory or a larger power supply than the 265 W unit fitted will also need a different platform.

Dual-drive storage configuration

The defining specification is the paired 512 GB SSD and 2 TB HDD, giving both rapid application loading and high-capacity file storage in one chassis. This layout removes the need to choose between speed and space at purchase. If your workflow demands a single larger solid-state volume instead, this specific drive pairing will not match that requirement.

Questions about this item

Does the 265 W power supply limit the i7-2600 when it runs at 3.90 GHz turbo for long periods?

The 265 W unit is sized for the i7-2600 and its dual-drive configuration, so the processor can sustain its 3.90 GHz turbo within the thermal envelope of the Mini Tower case.

How loud and hot does the Mini Tower get when the 2 TB hard drive and i7-2600 are active all day?

The 265 W supply and case airflow keep noise at typical office levels; the 3.5" 2 TB drive and i7-2600 run within normal temperature ranges for continuous operation.

Which DDR3 modules do I need if I want to expand the 8 GB to the 16 GB maximum?

Install two 8 GB DDR3 240-pin DIMMs to reach the 16 GB ceiling supported by the OptiPlex 790 motherboard.
