Dell OptiPlex 3090 UFF overview

The Dell OptiPlex 3090 UFF is an ultra-small-form-factor desktop built for office environments where desk space is limited. It ships with Windows 11 Pro and an Intel Core i5-1145G7 quad-core processor running up to 4.40 GHz. The system includes 16 GB of DDR4 memory at 3200 MHz and a 256 GB PCIe M.2 NVMe Class 35 SSD. Integrated Intel UHD Graphics drive the display outputs.

Who should consider this desktop

This configuration suits workers who need a compact, quiet PC for productivity applications, web-based tools and multi-monitor setups via DisplayPort 1.4 and USB-C with DisplayPort Alt Mode. It is not aimed at buyers who require a discrete graphics card for 3D rendering or gaming. The chassis lacks an optical drive and a media-card reader, so users dependent on legacy discs or SD cards should look elsewhere.

The specification that decides fit

The single M.2 2230 slot for PCIe solid-state storage is the limiting factor for capacity upgrades. Only 2230-length NVMe drives are supported, ruling out the far more common 2280 form factor. If your workload demands terabytes of fast local storage, this platform cannot accommodate it.

Questions about this item

What limits sustained performance of the i5-1145G7 in this 96.10 mm wide chassis?

The ultra-small form factor restricts cooling capacity, so the quad-core processor will hit thermal limits before the 8 MB cache or 4.40 GHz boost can be maintained continuously.

How loud and hot does the 3090 UFF get when running all day?

The compact 256.20 mm tall case uses a small internal fan that spins faster under load, producing noticeable airflow noise and warm exhaust air at the rear vents.

Which display cable do I need for the DisplayPort 1.4 output?

A standard DisplayPort cable connects the rear port to your monitor; the port also carries audio if the display supports it.
