Compact business desktop

The Dell OptiPlex 7090 Micro packs an 8-core Intel Core i7-10700T processor, 8GB of DDR4 memory and a 1TB NVMe M.2 SSD into a mini PC chassis. Windows 11 Pro is pre-installed and activated for immediate deployment. Integrated Intel UHD Graphics 630 drives up to two displays via DisplayPort connections.

Suits space-constrained offices.

This micro form factor fits behind a monitor or on a crowded desk, making it ideal for general productivity, multi-monitor setups and managed fleet roll-outs. Buyers who need a dedicated graphics card, internal expansion slots or user-upgradable storage bays should consider a larger chassis instead.

35-watt 8-core processor defines thermal envelope

The i7-10700T runs at a 35 W base power with 16 MB of L3 cache, delivering multi-threaded performance within the passive airflow limits of the Micro case. This power level determines the class of workloads the system can sustain without throttling.
