DELL OptiPlex 790 Mini Tower

The DELL OptiPlex 790 is a compact Mini Tower desktop built for everyday office and study tasks. It ships new with Windows 10 Pro 64-bit, a USB keyboard and a USB mouse included in the box. An Intel Core i5-2400 quad-core processor running at 3.10 GHz provides four threads for standard productivity workloads. Integrated Intel HD Graphics 2000 drives display output without a discrete card.

Suited for general office, education and home admin

This system suits buyers who need a ready-to-use Windows 10 Pro machine for document editing, web browsing and legacy business applications. The 16 GB DDR3 memory and 512 GB 2.5-inch SSD give responsive boot and multitasking performance for those workloads. Buyers who want more storage or faster graphics for modern gaming, video editing or 3D rendering should look at something else. The four memory slots are fully populated, so no further RAM upgrades are possible without removing modules.

512 GB SSD and 16 GB DDR3 headroom

The 512 GB solid-state drive comfortably holds the operating system, office suites and a large document library with space to spare. Sixteen gigabytes of DDR3-240-pin memory handles dozens of browser tabs and typical office programs without paging. Storage headroom runs out when users accumulate large media libraries or project files that exceed the half-terabyte capacity. Memory headroom ends at the 16 GB maximum supported by the Intel Q67 chipset, limiting virtual machines or memory-intensive workloads.

Questions about this item

Will the four DDR3 DIMM slots already be filled by the 16 GB kit?

Yes, the 16 GB ships as four 4 GB modules occupying all four 240-pin slots, leaving no free sockets for extra memory.

Can the integrated Intel HD Graphics 2000 drive a second monitor through the motherboard video outputs?

The board provides VGA and DisplayPort; both can be active simultaneously for dual-display extended desktop at supported resolutions.

How do I confirm the 512 GB SSD is recognised at full capacity after first boot?

Open Disk Management in Windows 10 Pro — the drive should appear as a single 512 GB partition with the NTFS file system and a healthy status.
