DELL OptiPlex 3090 Micro i5-10500T 16GB 256GB NVMe desktop PC

Dell OptiPlex 3090 Micro desktop

This Dell OptiPlex 3090 Micro is a compact business desktop powered by a 10th Gen Intel Core i5-10500T processor with six cores running at 2.30 GHz. It includes 16GB of DDR4 memory and a 256GB NVMe solid-state drive for fast boot and application loading. Integrated Intel UHD 630 graphics drive two DisplayPort outputs for dual-monitor setups. The 65W power supply keeps energy use low in office environments.

Practical limits of integrated graphics

The Intel UHD 630 integrated graphics handle everyday productivity, web browsing and video playback but are not suited for 3D rendering, CAD or modern gaming workloads. Two DisplayPort connectors support dual displays without adapters. Five USB 3.2 Gen1 ports provide 5 Gbps bandwidth for peripherals and external storage. A single RJ-45 Ethernet port gives wired network access; no wireless or Bluetooth capability is present.

Installation notes and common issues

The mini chassis measures 7.16 x 7.03 x 1.42 inches and weighs 2.31 lb, so it fits behind a monitor or in a small desk space with the included VESA mount. Memory uses DDR4 SO-DIMM slots; verify the maximum supported capacity before upgrading. The 256GB NVMe drive occupies the sole M.2 slot, so storage expansion requires an external USB drive. Windows 10 Pro 64-bit is pre-installed and activated.
