Dell OptiPlex 390 SFF Desktop

This Dell OptiPlex 390 is a small form factor desktop powered by an Intel Core i5 2nd Gen processor running at 3.10GHz. It comes with 8 GB of RAM, a 1 TB hard disk drive and Windows 10 Pro pre-installed. Integrated Intel HD Graphics drives both HDMI and VGA outputs, while built-in Wi-Fi and Ethernet provide network connectivity. The compact black chassis includes a DVD-ROM drive for legacy media.

Suited for office and casual use

The system targets office workers, industrial environments and casual computing tasks such as web browsing, document editing and email. The 16 GB maximum memory ceiling and integrated graphics make it unsuitable for buyers who need discrete GPU performance, more than 16 GB of RAM or internal expansion cards that require a full-size ATX power supply. Users who rely on faster solid-state storage should also note the mechanical hard drive.

16 GB maximum RAM capacity

The motherboard supports a maximum of 16 GB of memory, which is the key constraint when deciding whether this desktop can handle your workload. With 8 GB installed from the factory, only one upgrade step remains before the platform limit is reached. If your applications demand more memory headroom, this OptiPlex 390 will not meet the requirement.

Questions about this item

How loud and warm does the OptiPlex 390 SFF get when running all day?

The small form factor chassis uses integrated Intel HD Graphics and a 3.10 GHz Core i5, so heat output stays modest and the single system fan runs quietly during typical office workloads.

What must I already own to start using this desktop?

You need a monitor with HDMI or VGA input, a USB keyboard and mouse, and a wired Ethernet cable for the built-in network port.

Will my older VGA-only monitor work with the OptiPlex 390?

Yes, the system provides both HDMI and VGA video outputs, so a legacy VGA display connects directly without an adapter.
