Dell OptiPlex 990 Mini Tower Desktop

This Dell OptiPlex 990 Mini Tower is a desktop computer built for everyday computing. It runs on an Intel Core i7-2600 quad-core processor at 3.40 GHz with 3.80 GHz Turbo Boost. The system includes 8 GB DDR3 RAM, a 256 GB SSD, and a 2 TB hard drive. Windows 10 Pro 64-bit is pre-installed with a USB keyboard and mouse.

Ideal for Home Office and Student Use

This configuration suits students and home office users handling documents, web browsing, and email. The combined 256 GB SSD and 2 TB HDD provide fast boot times and ample file storage. Buyers who need dedicated graphics for modern gaming or video editing should look elsewhere. Systems requiring more than 8 GB RAM or a higher-wattage power supply for upgrades are not a match.

265 W Power Supply Limits Upgrades

The 265 W power supply is the single specification that decides whether this chassis supports additional components. It restricts the installation of discrete graphics cards or multiple extra drives. The Intel HD Graphics 2000 integrated GPU handles basic display output only. Verify the power budget before adding any expansion cards or storage devices.

Questions about this item

What monitor connection does the Intel HD Graphics 2000 require for the DELL OptiPlex 990?

The integrated Intel HD Graphics 2000 provides video output through the motherboard ports; connect a VGA or DisplayPort cable from your monitor to the rear I/O panel.

Will my existing DDR3 memory modules work alongside the installed 8 GB in this OptiPlex 990?

The system uses 240-pin DDR3 DIMMs; matching DDR3 modules can be added to the available slots up to the 16 GB maximum supported by the platform.

How can I verify the Intel Core i7-2600 reaches its 3.80 GHz turbo speed after setup?

Open Task Manager in Windows 10 Pro, select the Performance tab, and watch the CPU frequency climb to 3.80 GHz when a single-threaded load is applied.
