Dell OptiPlex 790/990 SFF Desktop

The Dell OptiPlex 790/990 SFF is a compact desktop computer built around a 3.4 GHz Intel Core i5 2nd Gen processor with 4 GB of memory. It ships with Windows 7 Professional and a 250 GB hard drive for everyday office tasks. Integrated Intel HD Graphics drive the DisplayPort output for a single monitor.

Verify DisplayPort monitor and USB 2.0 peripherals

Confirm that your display accepts a DisplayPort signal or that you have a suitable adapter for HDMI or VGA. The system provides USB 2.0 ports for keyboard, mouse and the included Wi‑Fi adapter. Ensure the small form factor chassis fits your allocated desk space before ordering.

Integrated graphics share system memory under load

The on‑board Intel HD Graphics uses a portion of the 4 GB RAM during sustained graphical work, reducing memory available to applications. The mechanical hard drive delivers consistent throughput for sequential reads but exhibits higher latency than solid‑state storage during prolonged random access. Thermal throttling is unlikely in typical office workloads.
