Ready-to-use desktop for everyday tasks

The Dell OptiPlex 990 Mini Tower arrives with Windows 10 Pro 64-bit pre-installed and includes a USB keyboard and mouse. A 2nd Gen Intel Core i7-2600 processor running at 3.40 GHz with 3.90 GHz Turbo Boost works alongside 16 GB of DDR3 RAM and a 512 GB SSD for responsive general computing.

Best for office and study use

This system suits students and home-office users who need a complete, quiet PC for documents, web browsing and video playback. Buyers who want more storage than 512 GB or require a dedicated graphics card for modern gaming should look at other configurations.

Steady output within a 265 W power envelope

The 265 W supply and integrated Intel HD Graphics 2000 keep heat and fan noise low during long sessions of typical productivity workloads. Sustained heavy multi-threaded tasks will hit the thermal and power limits of the compact Mini Tower chassis before a larger workstation would.

Questions about this item

Does the Intel Core i7-2600 processor require a separate graphics card for basic display output?

No, the integrated Intel HD Graphics 2000 provides video output directly from the motherboard, so a discrete card is not needed for everyday use.

Can I reuse my existing DDR3 memory modules to expand the 16 GB already installed?

Yes, the system uses standard 240-pin DDR3 DIMMs, so compatible DDR3 modules can be added to the available slots.

How can I verify the 512 GB SSD is recognised and set as the boot drive after first startup?

Open Windows Disk Management or the BIOS setup utility; both will list the 2.5-inch 512 GB solid-state drive as the primary boot device.
