Dell OptiPlex 790 Mini Tower

The Dell OptiPlex 790 Mini Tower is a desktop computer built around an Intel Core i7-2600 quad-core processor running at 3.40GHz. It comes with 8GB of DDR3 memory and a 256GB 2.5-inch SATA SSD. 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.

Suits home office and student use.

This system suits home office and student users who need a ready-to-run Windows 10 Pro desktop with integrated Intel HD Graphics 2000 and Gigabit Ethernet. The four DIMM slots are already populated with 2GB modules, leaving zero free slots for additional RAM without removing existing memory. Buyers who want to expand memory beyond 8GB or who need discrete graphics performance should look at a different platform.

8GB DDR3 in four occupied slots

The motherboard provides four 240-pin DDR3 slots with a maximum supported capacity of 16GB. The current configuration installs 2GB x 4 modules, filling every slot and leaving none available for simple upgrades. Adding more memory requires replacing the installed modules.

Questions about this item

What comes in the box and what must I buy separately?

The system includes the OptiPlex 790 Mini Tower, a USB keyboard, a USB mouse, a WiFi USB adapter, Windows 10 Pro with CoA, 8 GB DDR3 RAM in four 2 GB DIMMs, a 256 GB 2.5" SATA SSD and a DVD±RW drive. All memory slots are populated, so extra DDR3 requires removing modules.

Should I choose the 8 GB or 16 GB DDR3 option for this 790?

The board has four 240-pin slots and supports up to 16 GB DDR3. The 8 GB configuration fills every slot with 2 GB modules; moving to 16 GB means replacing all four sticks. Pick 16 GB only if you need the extra capacity for heavier multitasking.

What does the 3.40 GHz i7-2600 deliver in everyday use?

The quad-core 2nd Gen i7-2600 runs at 3.40 GHz with 64-bit support and integrated Intel HD Graphics 2000. Paired with the 256 GB SATA SSD and 8 GB DDR3, it handles office applications, web browsing and video playback smoothly.
