Compact USFF desktop for office tasks

The Dell OptiPlex 990 USFF packs a 2.9 GHz to 3.30 GHz Intel Quad-Core i5 processor, 4 GB DDR3 RAM and a 256 GB 2.5" SSD into an ultra-small chassis. Windows 10 Pro 64-bit is pre-installed with a Certificate of Authenticity. Integrated Intel HD Graphics 2000 drives basic display output. A 16X DVD±RW drive, Gigabit Ethernet and a USB WiFi adapter handle media and connectivity.

Suits light productivity and legacy software

This system fits users who need a space-saving Windows 10 machine for document editing, web browsing or older business applications. The 4 GB memory and integrated graphics limit multitasking and rule out modern gaming, video editing or CAD work. Buyers who want more storage, additional RAM slots or a discrete graphics card should look at larger form factors.

Simple plug-in setup with limited expandability

Connect the included USB keyboard and mouse, add a monitor via the video port and power on. The USFF case restricts internal upgrades; only low-profile cards fit and the 240-pin DDR3 slots may already be populated. The external USB WiFi adapter can block adjacent ports on tight desks. Driver installation for the Q77 chipset and HD 2500 graphics may be required after a clean OS reload.

Questions about this item

What monitor connection do I need on my display for the Intel HD Graphics 2500 output?

The integrated Intel HD Graphics 2500 provides standard video outputs; match your monitor cable to the available port on the rear panel.

Will my existing DDR3 memory modules work alongside the installed 4 GB?

The system uses 240-pin DDR3 DIMM slots; any compatible DDR3 module of the same voltage and speed can be added if a free slot exists.

How can I verify the 256 GB SSD is recognised after first boot?

Open File Explorer or Disk Management in Windows 10 Pro; the 256 GB solid-state drive should appear as the primary C: volume.
