Ultra-Small Business Desktop

The Dell OptiPlex 3090 UFF is an ultra-small form factor desktop built for professional environments. It runs Windows 11 Pro on an Intel Core i5-1145G7 quad-core processor reaching 4.40 GHz. The system includes 16GB of 3200MHz DDR4 memory and a 256GB PCIe NVMe Class 35 solid-state drive. Integrated Intel UHD Graphics drive the display output.

Suits Space-Constrained Offices

This desktop suits offices needing a compact, quiet PC for productivity, web apps and multi-monitor setups via DisplayPort 1.4 and USB-C video. It is not for buyers who want more storage than 256GB, builders who need a second M.2 NVMe drive, or users requiring a dedicated graphics card or an optical drive. The single 2230 M.2 slot is occupied by the boot drive.

256GB PCIe NVMe Class 35 Boot Drive

The single specification that decides fit is the 256GB PCIe NVMe Class 35 solid-state drive in the sole M.2 2230 slot. It delivers fast boot and application loading for the installed Windows 11 Pro 64-bit OS. There is no second M.2 slot for additional NVMe storage, only a SATA 3.0 connector for a hard drive. Expanding capacity requires a SATA drive or external USB storage.
