Dell OptiPlex 790 Mini Tower

This Dell OptiPlex 790 Mini Tower desktop computer is built for home office and student use. It runs on an Intel 2nd Gen i7-2600 quad-core processor at 3.40 GHz with 4 GB of DDR3 memory. The system includes a 256 GB solid-state drive paired with a 2 TB hard drive for combined speed and capacity. Windows 10 Pro 64-bit comes pre-installed with a keyboard and mouse included.

Sustained load behaviour

The 265 W power supply supports the 64-bit quad-core CPU which can reach 3.90 GHz turbo speeds during extended workloads. Integrated Intel HD Graphics 2000 handles display output without a discrete card. Gigabit Ethernet and a USB wireless dongle provide network connectivity for long sessions. The DVD±RW drive remains available for optical media access throughout operation.

Upgrade context

This configuration replaces older desktops limited to mechanical storage by adding a 2.5-inch 256 GB SSD alongside the 3.5-inch 2 TB hard drive. The DIMM 240-pin memory slots support upgrades to 8 GB or 16 GB of DDR3 RAM for heavier multitasking. Buyers needing discrete graphics performance or newer processor architectures should consider alternative systems.
