DELL OptiPlex 990 SFF All-in-One 22" i7-2600 3.4GHz 8GB DDR3 512GB SSD Windows 10 Pro

Dell OptiPlex 990 SFF All-in-One

This desktop computer integrates the system unit and a 22-inch 1920 x 1080 monitor into a single slim form factor. It runs on a 2nd Gen Intel Core i7-2600 processor at 3.40 GHz with 8 GB of DDR3 RAM and a 512 GB SSD. Windows 10 Pro 64-bit is pre-installed along with a DVD-RW drive, USB keyboard and mouse. The package suits office workers or home users needing a compact, ready-to-use setup.

Check your workspace and peripherals

The all-in-one design uses a fixed 22-inch display with DVI-D and VGA video inputs, so you cannot swap the panel or add an internal graphics card. Verify that your desk accommodates the combined unit and that any external devices you plan to connect are compatible with USB 2.0 ports. The system ships with a USB Wi-Fi adapter for wireless networking and includes wired Ethernet. Memory upgrades are limited to a maximum of 16 GB of DDR3.

Sustained load behaviour

The quad-core i7-2600 can reach 3.80 GHz Turbo Boost speeds for short bursts, but the small form factor chassis restricts long-term thermal headroom. Under continuous multi-threaded workloads, expect clock speeds to settle below the peak turbo frequency as the cooling system manages heat within the slim enclosure. The 512 GB SSD maintains consistent read and write performance without the slowdowns seen on mechanical drives during extended file operations.
