OptiPlex 790 Mini Tower Desktop

The Dell OptiPlex 790 is a Mini Tower desktop computer built for student and home-office use. It ships new with a 64-bit quad-core Intel Core i5-2400 processor running at 3.10 GHz, 16 GB of DDR3 memory and a 1 TB 3.5-inch SATA hard drive. Windows 10 Pro 64-bit is pre-installed with a Certificate of Authenticity. A DVD±RW drive, USB keyboard and USB mouse are included in the box.

Who this suits and who it does not

This system suits buyers who need a ready-to-use desktop for everyday office tasks, web browsing and video playback. Integrated Intel HD Graphics 2000 handles basic display output only, so users who require discrete graphics performance for gaming or GPU-accelerated workloads should look elsewhere. All four DIMM slots are populated, leaving no room for memory expansion beyond the installed 16 GB.

Deciding specification — 16 GB DDR3 limit

The motherboard supports a maximum of 16 GB of DDR3 memory across four 240-pin slots and every slot is already filled with a 4 GB module. This fixed ceiling determines whether the computer can meet your multitasking needs or if a platform with higher memory capacity is required.

Questions sur cet article

Should I choose 4, 8, or 16 GB of DDR3 for the OptiPlex 790?

This unit ships with 16 GB DDR3 installed across four slots, reaching the 16 GB maximum the board supports. No further memory can be added.

What does the 3.10 GHz i5-2400 actually deliver in daily use?

The second-generation quad-core runs at 3.10 GHz base with a 3.30 GHz turbo, handling office apps, web browsing and 1080p video smoothly within its 64-bit architecture.

How does the SATA interface limit the 1 TB hard drive?

The 3.5-inch 1000 GB drive connects via SATA, capping sequential throughput at the bus limit and making boot and load times slower than an SSD would be.
