DELL OptiPlex 3090 desktop PC i5-10505 16GB DDR3 500GB SSD 24" monitor Windows 11 Pro

Ready for daily work

The Dell OptiPlex 3090 desktop arrives with an Intel Core i5-10505 processor, 16 GB of DDR3 memory and a 500 GB SSD, all running Windows 11 Pro. A 24 inch LCD monitor, keyboard and mouse are included so the system works straight from the box. It suits home office users, students or small businesses that need a complete, ready-to-use PC for browsing, email, video calls and document editing. Buyers who need discrete graphics performance or more than 64 GB of memory should look elsewhere.

Steady throughput

The six-core i5-10505 maintains consistent speeds during extended sessions of web-based apps, streaming or light multitasking because the 16 GB DDR3 module feeds data without bottlenecking the integrated graphics. The SATA SSD keeps boot and application load times predictable even after the drive fills, and the chassis airflow handles the thermal load of typical office workloads without throttling. Heavy rendering, compilation or gaming sessions will exceed the cooling and graphics headroom of this configuration.

Simple setup

Place the tower, connect the monitor via its video cable, plug in the keyboard and mouse, then press the power button — Windows 11 Pro completes the rest. The two memory slots allow a future upgrade to the 64 GB maximum if required, though the single 16 GB DDR3 stick occupies one slot already. The only common issue is forgetting to switch the monitor input source after first power-on, which leaves the screen blank until corrected.
