DELL OptiPlex 990 Desktop PC Intel Quad-Core i5 4GB 128GB SSD DVDRW WiFi Windows 10 Pro

Business desktop for everyday office work

The Dell OptiPlex 990 is a compact business desktop built around an Intel Quad-Core i5 processor and 4GB of DDR3 memory. It ships with Windows 10 Pro 64-bit and a pre-loaded Windows 7 Pro image for legacy compatibility. A 128GB solid-state drive and DVD-RW optical drive handle storage and media tasks. Integrated Intel HD Graphics 2000 drives standard office displays.

Connectivity limited to USB 2.0 and Gigabit Ethernet

Expansion relies on PCI, PCI Express x16, parallel and serial ports alongside multiple USB 2.0 interfaces. The Intel 82579LM controller provides wired Gigabit networking while a USB Wi-Fi adapter adds wireless capability. Dynamic Video Memory Technology 5.0 manages graphics memory allocation automatically. No faster USB or newer video outputs are present on this platform.

Replaces older Core 2 or single-core office PCs

The jump from legacy dual-core or single-core systems to a Quad-Core i5 delivers tangible multitasking responsiveness for document editing, web browsing and line-of-business applications. Buyers who need more than 4GB of RAM, a larger boot drive or discrete graphics for design workloads should look elsewhere. The 128GB SSD covers the OS and core apps but fills quickly with media libraries.
