Ultra-small desktop for home and office

The Dell OptiPlex 790 USFF is an ultra-small form factor desktop built around a 2nd Gen Intel quad-core i5-2400 processor running at 3.10 GHz. It ships with 4 GB of DDR3 memory and a 128 GB solid state drive for fast boot and application load times. Windows 10 Professional 64-bit is pre-installed, and a USB keyboard and mouse are included in the box.

Best for everyday tasks, not for heavy workloads

This system suits students, home-office users and anyone needing a compact PC for web browsing, document editing and media playback. Integrated Intel HD Graphics 2000 handles basic video output but cannot drive modern games or GPU-accelerated creative work. Buyers who need more memory, additional storage bays or discrete graphics should look at larger form factors.

128 GB SSD capacity decides fit

The 128 GB solid state drive determines whether this desktop can hold your operating system, applications and active files without external storage. If your workflow demands a larger local library, you will need to add drives or choose a system with greater capacity.

Questions about this item

How much fan noise and heat does the ultra-small Dell OptiPlex 790 produce when the Intel Core i5-2400 runs all day?

The ultra-small form factor uses a compact internal power supply and a low-profile cooler designed for the 3.10 GHz quad-core CPU; under continuous load the single system fan spins up only enough to keep the Intel HD Graphics 2000 and Q57 Express chipset within thermal limits, so noise stays at a quiet office level.

What display cable must I already own to connect a monitor to the Intel HD Graphics 2000 output on this Dell OptiPlex 790?

The integrated Intel HD Graphics 2000 provides a VGA port and a DisplayPort connector; you will need a VGA cable or a DisplayPort cable that matches the monitor input you plan to use.

Can I keep my existing DDR3 memory modules when upgrading the 4 GB of RAM installed in this OptiPlex 790?

Yes — the system uses DDR3 DIMMs, so any compatible DDR3 sticks you already have can be added to the two available slots up to the board's maximum capacity.
