DELL OptiPlex 3090 SFF desktop

The DELL OptiPlex 3090 SFF is a compact desktop computer built around an Intel Core i5-10400 processor running at 2.90 GHz. It comes with 16 GB of memory and a 512 GB M.2 solid-state drive. Windows 11 Pro is pre-installed, making it ready for casual computing and office tasks straight out of the box. Integrated Intel UHD Graphics 630 handles the display output.

Windows 11 Pro and connectivity ports

Windows 11 Pro provides the operating environment with professional features such as BitLocker and remote desktop. The chassis offers DisplayPort and HDMI video outputs for dual-monitor setups. USB 2.0 and USB 3.2 ports are available for peripherals and external storage. No monitor is included in the package.

Small Form Factor installation notes

The Small Form Factor chassis saves desk space but limits internal expansion to low-profile cards. Memory can be increased up to 64 GB using the available slots. Builders who need a discrete graphics card or multiple 3.5-inch drives will find the case restrictive. Ensure any add-in card matches the low-profile bracket requirement.

Questions about this item

Can the 512GB M.2 SSD be swapped for a larger drive later?

Yes, the M.2 slot accepts a replacement SSD; the board also has a 2.5-inch bay if you prefer to add a second drive instead.

What limits performance first when the Core i5-10400 runs at 2.90GHz for long periods?

The integrated UHD 630 graphics share system memory, so sustained heavy GPU workloads hit the 16GB RAM ceiling before the CPU throttles.

How loud and hot does the SFF chassis get during an all-day office workload?

The small form factor relies on a single system fan; under typical desk tasks it stays quiet and the case remains warm but not hot to the touch.
