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 Turbo Boost up to 3.80 GHz. It ships with 8 GB of DDR3 memory, a 128 GB solid-state drive and a 2 TB hard drive. Windows 10 Pro 64-bit is pre-installed and a USB keyboard and mouse are included.

Upgrade From Older Dual-Core Systems

This configuration replaces aging dual-core desktops that struggle with modern multitasking and slow mechanical boot drives. The quad-core i7-2600 and included SSD deliver responsive application launches and smoother background task handling. The jump is worth it when your current machine stalls on everyday office workloads or web browsing with multiple tabs open.

Sustained Load With 265W Power Supply

Under continuous load the 265 W power supply supports the 65 W TDP processor and integrated Intel HD Graphics 2000 without thermal throttling in typical office environments. The mini-tower chassis provides adequate airflow for extended rendering, compilation or backup tasks. The dual-drive layout keeps the operating system on flash storage while the hard drive handles bulk sequential writes.

Questions about this item

What power supply wattage does the OptiPlex 990 Mini Tower require?

The system uses a 265W power supply. Ensure any replacement matches this rating and the proprietary Mini Tower form factor connectors.

How do I install additional DDR3 memory in the 240-pin DIMM slots, and what mistake should I avoid?

Open the chassis, align the notch on the DDR3 module with the 240-pin slot key, and press firmly until the retention clips click. The common error is stopping before the clips engage fully.

When should I consider replacing the 128 GB SSD or 2 TB hard drive?

Replace the SSD if SMART tools report declining health or write endurance nears its limit. Replace the 2 TB hard drive if you hear unusual noises, see reallocated sectors, or experience slow file access.
