DELL OptiPlex 5090 SFF i5-10400 8GB 256GB SSD desktop PC

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.
