Ultra Small Form Factor Business Desktop

The Dell OptiPlex 3090 UFF is a compact business desktop built around an Intel Core i5-1145G7 quad-core processor. It ships with 16GB of DDR4 memory and a 256GB NVMe solid-state drive. Windows 11 Pro is pre-installed for immediate deployment in professional environments. The 10.09-inch height and 3.78-inch width allow placement in tight workspaces.

Wireless Connectivity and Video Output Bundle

Integrated Intel UHD Graphics drive a DisplayPort 1.4 output for external monitors. A Qualcomm QCA61x4a module provides 802.11 ac dual-band Wi-Fi and Bluetooth 5 for cable-free networking and peripherals. The side-mounted USB 3.2 Gen 2 Type-A port supports PowerShare for charging devices while the system is off. Rear ports include two SmartPower On USB Type-A ports and a USB Type-C port with DisplayPort Alt Mode and power delivery.

16GB Memory and 256GB Storage Headroom

The single 16GB DDR4 module runs at up to 3200MHz and leaves one slot free for expansion up to the platform limit. The 256GB PCIe M.2 NVMe Class 35 drive handles operating system, applications and active project files with fast access speeds. An internal SATA 3.0 connector and a second M.2 2230 slot provide pathways for additional storage when local capacity is exhausted. Integrated graphics suit office productivity and multi-monitor setups but cannot accommodate 3D rendering or GPU-accelerated workloads.

Questions about this item

Will the 256GB NVMe drive need upgrading for more storage?

Yes, a second M.2 2230 PCIe slot is available inside the chassis for adding another NVMe drive.

What limits the Intel Core i5-1145G7 during long workloads?

The ultra-small 10.09-inch high chassis restricts cooling, so sustained turbo speeds will throttle once the thermal ceiling is reached.

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

The compact 3.78-inch wide form factor uses a small internal fan that becomes audible under load, and surface temperatures rise noticeably after hours of continuous use.
