Dell OptiPlex 990 Mini Tower Desktop

This Dell OptiPlex 990 Mini Tower desktop computer is powered by an Intel 2nd Gen Core i7-2600 quad-core processor running at 3.40 GHz with turbo up to 3.90 GHz. It includes 16 GB of DDR3 memory, a 256 GB solid-state drive, a 1 TB hard drive, and a DVD-RW drive. Windows 10 Pro 64-bit is pre-installed with a USB keyboard and mouse included.

Home office and general business users

The system suits home office workers, students, and general business users who need a ready-to-use desktop for documents, email, and web browsing. Buyers who need dedicated graphics performance for modern gaming or intensive 3D rendering should look at other configurations. The integrated Intel HD Graphics 2000 handles standard display output and video playback only.

265 W power supply capacity

The 265 W power supply determines which additional components can be installed inside the Mini Tower chassis. This wattage supports the included processor, memory, and storage drives with limited headroom for upgrades. Any added expansion cards or drives must stay within this power budget.

Questions about this item

How loud or hot does the 265 W power supply run when the i7-2600 operates at 3.90 GHz Turbo Boost all day?

The 265 W supply powers the quad-core i7-2600 and integrated Intel HD Graphics 2000; typical office workloads keep thermals and fan noise low.

Which display cable do I need to connect my monitor to the Intel HD Graphics 2000 output on this OptiPlex 990?

The integrated graphics provide standard video ports — use the matching cable for your monitor’s input.

Will my existing DDR3 memory modules work alongside the installed 16 GB if I want to expand later?

The system uses 240-pin DDR3 DIMM slots; any compatible DDR3 module can be added up to the board limit.
