Dell OptiPlex 990 Mini Tower Desktop

The Dell OptiPlex 990 Mini Tower is a desktop computer built around an Intel Core i7-2600 processor running at 3.40 GHz with a 3.90 GHz turbo frequency. It comes with 16 GB of DDR3 RAM and a 2.5-inch 256 GB solid-state drive for the operating system and applications. Windows 10 Pro 64-bit is pre-installed, and a 16X DVD±RW drive handles optical media. A USB keyboard and mouse are included in the box.

Suited to office productivity and legacy software

This system suits users who need a familiar Windows 10 environment for document work, web browsing or older business applications that run on a 2nd-generation quad-core CPU. The integrated Intel HD Graphics 2000 and 265 W power supply limit the machine to basic display output, so buyers who want discrete graphics performance or modern gaming capability should look elsewhere.

Steady output within a 265 W envelope

Under sustained load the four-core processor maintains operation within the 265 W unit, while the SSD keeps read and write latency low compared with mechanical drives. The DDR3 memory subsystem provides 16 GB of capacity for multi-tasking, and Gigabit Ethernet delivers consistent wired network throughput for long transfers or remote sessions.

Questions about this item

Does the OptiPlex 990 Mini Tower include a display or must I supply my own?

The system is sold without a monitor; you will need to provide one with a VGA or DisplayPort input.

Can I keep my existing DDR3 memory modules when upgrading this desktop?

The board uses 240-pin DDR3 DIMM slots, so any compatible DDR3 sticks you already own can be installed alongside the 16 GB supplied.

How can I verify the Intel HD Graphics 2000 is active after setting up Windows 10 Pro?

Open Device Manager, expand Display adapters, and confirm Intel HD Graphics 2000 appears without a warning icon.
