Tower workstation for business users

The Dell OptiPlex 7090 Tower is a business desktop built around a 10th-generation Intel Octa-Core i7-10700 processor with 8 cores and 16 threads reaching up to 4.80 GHz. It ships with 8 GB of DDR4 memory, a 512 GB M.2 solid-state drive plus a 1 TB solid-state drive, and Windows 10 Pro. A USB keyboard and mouse are included, while a monitor is not.

Step up from dual-core or quad-core office PCs

Replacing an older dual-core or quad-core system with this octa-core tower adds headroom for heavy multitasking, large spreadsheets and multiple business applications running together. The jump is worth it when daily workloads exceed the thread count or memory ceiling of the current machine and the included dual-drive layout simplifies separating the operating system from data storage.

Suits offices needing manageable.

This configuration suits IT-managed environments that value tool-less chassis access, legacy optical media support via the 16X DVD±RW drive and dual DisplayPort 1.4 outputs for two monitors. Buyers who need discrete graphics performance, more than 8 GB of memory out of the box, or a smaller form factor for space-constrained desks should look at other models.

Questions about this item

Will the Dell OptiPlex 7090 Tower fit on a standard desk?

The tower chassis is designed for floor or desk placement and requires only a flat, stable surface with enough clearance for the rear ports and the DVD±RW tray to open.

What is the correct order to connect the power button and front USB cables during assembly?

Route the front-panel header cables through the chassis clips before securing the motherboard, then attach the power-switch and USB 2.0 leads to the labelled pins on the board.

Which memory modules can be used to expand the 8 GB DDR4 later?

The system uses DDR4 UDIMM memory and supports a maximum of 64 GB total capacity.
