Dell OptiPlex 790 Mini Tower for home office

This desktop computer ships as a complete system with an Intel Core i7-2600 quad-core processor running at 3.40GHz. It includes 16 GB of DDR3 memory and a 512 GB 2.5-inch SATA solid state drive. Windows 10 Pro 64-bit is pre-installed with a Certificate of Authenticity. A USB keyboard, USB mouse and a WiFi USB adapter are also supplied in the box.

Sustained load behaviour with integrated graphics

The Intel HD Graphics 2000 integrated GPU shares system memory and handles everyday office applications, web browsing and video playback without a discrete card. Under continuous multi-threaded workloads the four cores maintain their 3.40GHz clock within the Mini Tower chassis airflow. The 512 GB SSD keeps boot times and application launches consistent compared with mechanical drives. All four DIMM slots are populated so memory bandwidth remains stable during extended sessions.

16 GB DDR3 maximum memory limit

The motherboard supports a maximum of 16 GB across four 240-pin DIMM slots and this unit already uses every slot with 4 GB modules. Buyers who need more than 16 GB of RAM cannot upgrade this platform and should consider a different system. The 512 GB SATA SSD provides the primary storage and there is no 3.5-inch hard drive installed. Expansion is limited to the available PCIe slots inside the Mini Tower case.

Questions about this item

How loud is the mini-tower and how much heat does the i7-2600 3.40GHz produce when running all day?

The i7-2600 3.40GHz is a 64 bit quad-core processor; the mini-tower case vents through a rear exhaust fan and the integrated Intel HD Graphics 2000 adds minimal extra heat.

What must I already own for this OptiPlex 790 to work out of the box?

Only a mains cable and a display with VGA, DVI or DisplayPort input are required; a USB keyboard and mouse are included in the box.

Will my existing DDR3 modules fit alongside the installed 16 GB in the four 240-pin slots?

All four 240-pin DDR3 slots are already populated with 4 GB modules, so no further DDR3 memory can be added without removing existing sticks.
