Compact SFF desktop for everyday work

The Dell OptiPlex 990 Small Form Factor desktop uses an Intel quad-core i5 processor running at 2.9 GHz with a 3.30 GHz turbo boost. It ships with 16 GB of DDR3 memory and a 512 GB 2.5 inch SSD. Windows 10 Pro 64-bit is pre-installed, and a keyboard plus mouse are included in the box.

Replaces an older hard-drive tower

Moving from a traditional mechanical drive to the 512 GB SSD cuts boot and application load times dramatically. The 16 GB DDR3 capacity handles multiple browser tabs and office suites without paging. The jump is worth it when your current system stalls on basic multitasking or takes minutes to reach the desktop.

Steady performance within SFF thermal limits

The integrated Intel HD Graphics 2000 and compact chassis are designed for sustained office workloads rather than extended heavy compute. Under continuous load the processor will balance clock speeds to stay within the small form factor thermal envelope. Gigabit Ethernet and the USB WiFi adapter provide reliable network throughput for typical business tasks.

商品問答

What size and type of drive bay does the 512 GB SSD need in the OptiPlex 990 SFF?

The solid-state drive is a 2.5 inch unit, so it mounts in a standard 2.5 inch internal bay or caddy inside the small-form-factor chassis.

How is the included WiFi USB adapter installed, and what step is often missed?

Plug the adapter into any free USB port, then install the driver from Windows Update or the Dell support site; the step often missed is running that driver install before expecting a wireless connection.

What memory specification must replacement modules match for this system?

Replacement modules must be DDR3 DIMMs with a 240-pin form factor to fit the OptiPlex 990 motherboard slots.
