Dell OptiPlex 790 Mini Tower

The Dell OptiPlex 790 Mini Tower is a desktop computer built around an Intel 2nd Gen i5-2400 quad-core processor running at 3.10 GHz with a 3.40 GHz turbo boost. It comes equipped with 16 GB of DDR3 memory, a 128 GB solid-state drive and a 2 TB hard drive. Windows 10 Pro 64-bit is pre-installed. A USB keyboard and mouse are included in the box.

Who this suits and who should look elsewhere

This system suits students, home-office workers and general users who need a responsive machine for web browsing, document editing and light multitasking. The dual-drive layout gives fast boot times plus large bulk storage. Buyers who need dedicated graphics performance for modern gaming or GPU-accelerated creative workloads should look elsewhere, as the platform relies on integrated Intel HD Graphics 2000 only.

Capacity and headroom

The 128 GB SSD handles the operating system and frequently used applications comfortably, while the 2 TB hard drive provides ample room for media libraries, backups and project files. 16 GB of DDR3 memory offers headroom for running multiple browser tabs and office suites simultaneously. The 265 W power supply and Mini Tower chassis limit the scope for adding high-power expansion cards or additional internal drives.

商品問答

What monitor inputs do I need for the Intel HD Graphics 2000 built into the i5-2400?

The integrated Intel HD Graphics 2000 drives VGA and DisplayPort outputs on the OptiPlex 790 Mini Tower, so your monitor must accept one of those connections.

Will my existing DDR3 240-pin DIMMs work if I keep them alongside the installed 16 GB?

The system uses DDR3 240-pin DIMM slots; any matching DDR3 modules you already own can be added provided total capacity stays within the board limit.

How can I confirm the 128 GB SSD is set as the Windows 10 boot drive after first power-on?

Open Settings > System > Storage and verify the 128 GB drive shows the Windows logo and is labelled as the boot device.
