DELL OptiPlex 3090 SFF desktop PC 16GB 512GB PCIe Core i5-10500 3.2GHz Windows 11 Pro Black

Ready for office and study

The Dell OptiPlex 3090 SFF is a compact desktop built around an Intel Core i5-10500 hexa-core processor running at 3.2 GHz with 6 MB L3 cache. It ships with 16 GB of DDR4 memory and a 512 GB PCIe solid-state drive. Windows 11 Pro is pre-installed, and a wired keyboard plus wired mouse are included in the box. Integrated Intel UHD Graphics 630 drives up to two displays.

Simple drop-in deployment

The small form factor chassis fits on a desk or behind a monitor with minimal cabling. Installation is limited to connecting power, network and display cables; no internal assembly is required. The integrated graphics and single PCIe storage device mean there are no discrete cards to seat or extra power connectors to manage. Buyers who need an optical drive or a built-in media card reader will not find them on this model.

Connectivity and expansion ceiling

Wired networking tops out at 10/100/1000 Mbps while wireless uses IEEE 802.11n. Memory can be expanded to 32 GB total, but the slim chassis restricts the addition of full-height expansion cards or 2.5-inch drive bays. The platform does not support discrete graphics upgrades, so workloads requiring dedicated GPU acceleration fall outside its practical envelope.
