Compact Business Desktop

The Dell OptiPlex 790 SFF is a small form factor desktop built around an Intel Quad-Core i5 processor running between 2.9 GHz and 3.30 GHz. It comes with 8 GB of DDR3 memory and a 256 GB solid state drive. Windows 10 Professional 64-bit is pre-installed with a Certificate of Authenticity. Integrated Intel HD Graphics 2000 handles display output while Gigabit Ethernet provides wired networking. A DVD-RW drive USB keyboard and USB mouse are included in the box.

Fits Basic Office and Home Tasks

This system suits students home-office users and anyone needing a reliable machine for web browsing document editing email and video playback. The compact SFF chassis saves desk space and the included peripherals mean it is ready to use immediately. Buyers who want more storage than 256 GB or who need dedicated graphics performance for gaming or creative workloads should look at a different configuration. The maximum supported memory is 16 GB of DDR3 so users planning heavy multitasking beyond that limit will need another platform.

256 GB SSD Capacity Decides Fit

The single specification that determines whether this is the right part is the 256 GB solid state drive. It sets the total space available for the operating system applications and personal files. If your workload requires a larger boot drive or additional internal bays for extra drives this unit will not meet that need. The drive uses a 2.5 inch form factor and the platform supports DDR3 memory only.

Questions about this item

What does the Gigabit Ethernet port cap at in practice?

The integrated Gigabit Ethernet port is limited to 1 Gbps maximum throughput on wired networks.

What physical clearance does the small form factor case require for the 2.5" SSD?

The SFF chassis accepts a 2.5 inch drive in its dedicated bay; no 3.5 inch adapter is needed.

How is the DDR3 memory installed, and which step do people often miss?

Insert each 240-pin DIMM into the motherboard slots until the retention clips click; the step often missed is pressing both ends down evenly so both clips engage.
