Compact desktop for everyday work

The Dell OptiPlex 790 SFF is a small-form-factor desktop built around an Intel quad-core i5 running at 2.9 to 3.30 GHz with 8 GB of DDR3 memory and a 1 TB 3.5-inch hard drive. It ships with Windows 10 Professional 64-bit pre-installed, a DVD-RW drive, USB keyboard and mouse, plus integrated Gigabit Ethernet, Wi-Fi and Bluetooth. The integrated Intel HD Graphics 2000 handles standard office displays.

Straightforward SFF access

The small-form-factor chassis opens with a latch so you can reach the two 240-pin DIMM slots, the 3.5-inch drive bay and the low-profile expansion slot. Memory upgrades use DDR3 modules only; the board supports a maximum of 16 GB. The slim case accepts only half-height cards, so full-height graphics or add-in cards will not fit. Cable routing is tight, so route SATA and power leads carefully when swapping the hard drive.

Verify your peripherals and space

Confirm your monitor has a VGA, DisplayPort or HDMI input that matches the video outputs on this unit. The system includes USB keyboard and mouse, so no PS/2 ports are required. Ensure the intended location accommodates the SFF footprint and allows airflow through the side vents. Check that your network infrastructure provides a wired Gigabit connection or that the built-in Wi-Fi meets your signal requirements.

Questions about this item

How do I confirm the Intel Quad-Core i5 is running at 2.9 GHz to 3.30 GHz after setup?

Open Task Manager in Windows 10 Pro, select the Performance tab, and watch the CPU frequency readout while the system idles and under load; it should sit near 2.9 GHz at rest and boost toward 3.30 GHz when all four cores are busy.

The listing mentions a USB keyboard and mouse — are any cables or adapters needed to use them?

No extra cables or adapters are required; both peripherals plug directly into the USB ports on the SFF chassis and work immediately with Windows 10 Pro.

The spec sheet notes max memory is 16 GB DDR3 — should I buy 8 GB more now or wait?

The board has four 240-pin DDR3 slots and supports up to 16 GB total; if you already run heavy multitasking, add another 8 GB matched kit now, otherwise the installed 8 GB handles typical home-office work.
