DELL OptiPlex 790 Mini Tower Desktop

This DELL OptiPlex 790 Mini Tower desktop computer is built around an Intel 2nd Gen i5-2400 quad-core processor running at 3.10 GHz with a 3.40 GHz turbo boost. It ships as new with 8 GB of DDR3 RAM, a 512 GB 2.5-inch solid-state drive, a 2 TB 3.5-inch hard drive, a DVD±RW optical drive, integrated Intel HD Graphics 2000, gigabit Ethernet, a USB wireless dongle, Windows 10 Pro 64-bit, and a 265 W power supply in a black and silver mini-tower case with included USB keyboard and mouse.

Suits office and study tasks.

The configuration suits students, home-office users and general business workloads that rely on web browsing, document editing and light multitasking with the speed of an SSD boot drive and the capacity of a large mechanical drive. Buyers who need discrete graphics performance for modern gaming, video editing or 3D rendering will not find that capability in the integrated Intel HD Graphics 2000 subsystem.

Dual-drive storage: 512 GB SSD plus 2 TB HDD

The single specification that decides fit is the combined storage layout: a 512 GB 2.5-inch solid-state drive for the operating system and applications paired with a 2 TB 3.5-inch hard drive for bulk data. This dual-drive arrangement delivers fast boot and load times alongside generous file space without requiring the buyer to add a second drive after purchase.

Questions about this item

How do I add more memory to the OptiPlex 790, and which step is often missed?

Open the Mini Tower case, locate the 240-pin DDR3 slots, and insert the modules until the retention clips click; the step often missed is pressing firmly on both ends so each clip locks automatically.

What maintenance or replacement will the OptiPlex 790 need later?

The 265W power supply and the DVD±RW drive are the moving parts most likely to need replacement after extended use.

What limit appears first when the OptiPlex 790 runs sustained workloads?

The 265W power supply caps total system draw, so the CPU will throttle before the 3.40 GHz turbo boost can be maintained continuously.
