DELL OptiPlex 790 USFF Desktop PC i5-2400 3.10GHz 4 GB DDR3 256 GB SSD

Compact desktop for everyday tasks

The Dell OptiPlex 790 USFF is an ultra-small desktop computer powered by a 2nd Generation Intel Core i5-2400 processor running at 3.10 GHz with 4 GB of DDR3 RAM. It includes a 256 GB SSD, a 16X DVD±RW drive, integrated Intel HD Graphics 2000, Gigabit Ethernet, USB keyboard and mouse, and Windows 10 Pro 64-bit pre-installed. Designed for student or home-office use, it delivers basic productivity performance in a space-saving black and silver chassis.

DDR3 memory and legacy expansion only

The system uses DDR3 memory technology and provides PCI and PCI Express x16 slots alongside Parallel, Serial and multiple USB 2.0 ports for adding peripherals. Integrated graphics rely on the Intel Q57 Express chipset with Intel HD Graphics 2000, so display output is limited to the onboard video connectors. The 16X DVD±RW drive handles optical media, while Gigabit Ethernet supplies wired networking at up to 1 Gbps. No newer memory types, faster USB standards or discrete graphics support are present.

Check power, space and OS needs

Before ordering, verify that the ultra-small form factor fits your intended location and that the included 64-bit Windows 10 Pro licence meets your software requirements. The 4 GB DDR3 RAM and 256 GB SSD are fixed at the listed capacities, so buyers needing more memory or storage should look elsewhere. Ensure your monitors match the available video outputs on the integrated graphics, and confirm that any add-in cards you plan to install are compatible with the PCI and PCI Express x16 slots provided.
