OptiPlex 5090 SFF business desktop

The Dell OptiPlex 5090 SFF is a small form factor desktop built for office environments. It ships with Windows 11 Pro, an Intel Core i5-10400 six-core processor, 8GB of DDR4 memory and a 256GB SSD. The compact grey chassis measures 93 mm wide, 290 mm deep and 293 mm high, starting at 4.43 kg.

Upgrading from older SFF workstations

This unit replaces ageing small form factor PCs that lack modern connectivity or 10th Generation Intel performance. The jump is worthwhile when current hardware struggles with multi-tasking, lacks USB 3.2 Gen2 Type-C or requires Windows 11 Pro out of the box. It is not suited for buyers who need discrete graphics performance or higher storage capacity without adding drives.

Build integration for office deployments

The chassis provides two DisplayPort outputs, multiple USB 3.2 Gen1 Type-A ports, a USB 3.2 Gen2 Type-C port and RJ-45 networking. Expansion includes a PCIe x16 slot, a PCIe x4 open-ended slot and two PCIe x1 slots for add-in cards. An optional port bay supports VGA, DisplayPort 1.4, HDMI 2.0b or USB Type-C. No wireless card is installed; an external antenna jack is present for optional Wi-Fi.

Questions about this item

What clearance does the 93 mm wide SFF chassis need to fit on a shelf?

The small form factor case is 93 mm wide, 290 mm deep and 293 mm high; allow a few millimetres extra on each side for cable routing and airflow.

Which screw must be removed before the side panel slides off during installation?

Loosen the single thumbscrew at the rear edge of the cover, then slide the panel toward the back to release it; forgetting the thumbscrew is the most common mistake.

When will the DDR4 memory need to be upgraded beyond the installed 8 GB?

Add a second 8 GB DDR4 module when multitasking slows, or replace both slots with 16 GB sticks for 32 GB total if workloads demand it.
