Dell OptiPlex 990 Mini Tower desktop

This Dell OptiPlex 990 Mini Tower desktop is built for office work and home study. It runs Windows 10 Professional 64-bit on an Intel Core i7-2600 processor with 16 GB of DDR3 RAM. A USB keyboard and mouse are included in the box. The system fits a standard mini-tower chassis.

Sustained load behaviour

The Intel Core i7-2600 quad-core CPU operates at a 3.40 GHz base frequency and can reach 3.80 GHz turbo speeds when thermal headroom allows. Integrated Intel HD Graphics 2000 handles basic display output without a discrete card. The 265 W power supply delivers power to the processor, memory, and both storage drives during extended sessions.

Deciding specification

Storage combines a 2.5-inch 256 GB solid-state drive for the operating system and a 3.5-inch 2 TB hard drive for bulk data. This dual-drive layout gives fast boot times plus high capacity in one unit. Buyers who need a faster graphics subsystem or a different memory generation should consider other configurations.

Questions about this item

How loud and hot does the 265W power supply run when the i7-2600 hits 3.80 GHz Turbo Boost all day?

The 265W supply powers the Intel i7-2600 at 3.40 GHz base and 3.80 GHz Turbo Boost; actual acoustics and thermals depend on case airflow and ambient temperature.

Which display cable do I need for the Intel HD Graphics 2000 output on this OptiPlex 990?

The integrated Intel HD Graphics 2000 provides standard video outputs; check the rear panel for VGA, DisplayPort or DVI and use the matching cable for your monitor.

Will my existing DDR3 240-pin DIMMs work alongside the installed 16 GB if I want more memory?

The board uses DDR3 240-pin DIMM slots; additional modules must be DDR3 240-pin to be compatible with the current 16 GB configuration.
