Dell OptiPlex 990 Mini Tower desktop

This Dell OptiPlex 990 Mini Tower desktop computer is built for everyday office and home tasks. It runs on an Intel 2nd Gen i7-2600 processor at 3.40GHz with 16GB of DDR3 RAM. Windows 10 Professional 64-Bit comes pre-installed for immediate use.

Included keyboard mouse and dual storage

A USB keyboard and USB mouse are bundled so the system is ready to work out of the box. The 512GB SSD provides fast boot and application loading while the 2TB hard drive adds large capacity for files. A 16X DVD±RW drive handles optical media.

265W power supply limits upgrades

The 265W power supply supports the installed components but restricts the addition of high-power graphics cards or extra drives. Buyers who need a dedicated GPU or more internal peripherals should choose a system with a higher-rated PSU.

Questions about this item

When will the DDR3 memory need to be upgraded or replaced?

The system comes with 16 GB DDR3 installed across 240-pin DIMM slots; upgrade only if workloads exceed that capacity.

What limits sustained performance first during long sessions?

The 265 W power supply caps total draw, so the i7-2600 will throttle before thermals become the bottleneck.

How loud and hot does the mini tower get when running all day?

With a 265 W supply and integrated Intel HD Graphics 2000, heat output stays modest and the stock cooler runs quietly under typical office loads.
