DELL OptiPlex 990 SFF Desktop i5 2.9-3.30GHz 16GB DDR3 500GB HDD DVDRW WiFi Win 10 Pro

Compact desktop for everyday work

The Dell OptiPlex 990 SFF is a small-form-factor desktop built around an Intel quad-core i5 processor running at 2.9 to 3.30 GHz with a 3.40 GHz turbo frequency. It ships with 16 GB of DDR3 memory and a 3.5-inch 500 GB hard drive. Integrated Intel HD Graphics 2000 handles display output while Gigabit Ethernet and a USB WiFi adapter provide network connectivity. Windows 10 Pro 64-bit is pre-installed and a USB keyboard and mouse are included.

Check power supply and expansion space

Verify that the proprietary power supply in the SFF chassis can support any graphics card or additional drives you may add later. The compact case limits full-height expansion cards to low-profile models only. Confirm that your monitor has a compatible video input for the integrated graphics outputs. Ensure you have a free USB port for the supplied WiFi adapter if wireless connectivity is required.

Included peripherals and operating system

The bundled USB keyboard and mouse let you start working immediately without buying separate input devices. Windows 10 Pro 64-bit arrives activated and ready for domain join, BitLocker and remote desktop features. The DVD±RW drive adds the ability to read and write optical media for software installation or data archiving. The USB WiFi adapter provides wireless networking without opening the case.
