OptiPlex 7090 Tower 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 running up to 4.80 GHz. It ships with 64 GB of DDR4 UDIMM memory and a 128 GB 2.5-inch solid-state drive. Windows 10 Pro is pre-installed alongside a USB keyboard and mouse.

Upgrade from older office towers

This system replaces ageing desktops that struggle with modern multitasking and 64-bit workloads. The jump is worth it when current machines cannot address enough memory or lack the thread count for concurrent business applications. Integrated Intel UHD Graphics drives two DisplayPort 1.4 monitors without a discrete card.

Suits general office deployments

It suits organisations deploying standardised fleets for productivity, web apps and dual-screen workstations. Buyers who need more storage or faster graphics for creative rendering should look at configurations with larger drives or discrete GPU options. The tower chassis allows internal expansion for future requirements.

Questions about this item

Will the 2.5" 128 GB SSD fit in a standard 2.5" drive bay?

The 2.5" 128 GB SSD is designed for a standard 2.5" drive bay inside the tower chassis.

How do I install the 64 GB DDR4 UDIMM modules, and what is the common mistake?

Insert each DDR4 UDIMM into the motherboard DIMM slots until the retention clips click; the common mistake is not pressing firmly enough to engage both clips.

When should I replace the 16X DVD±RW drive?

Replace the 16X DVD±RW drive if it fails to read or write discs, makes unusual noises, or is no longer recognised by Windows 10 Pro.
