DELL OptiPlex 5040 SFF desktop PC i5-6500 3.20GHz 8GB 512GB SSD WiFi DVDRW Windows 10 Pro

Compact business desktop

The Dell OptiPlex 5040 SFF is a small-form-factor desktop computer built for office environments where desk space is limited. It ships with Windows 10 Professional pre-installed and includes a USB Wi-Fi adapter for wireless connectivity. The chassis measures 11.4 by 11.5 by 3.6 inches and weighs 10.7 pounds. A DVD-RW drive is fitted as standard.

Quad-core i5-6500 processor

The system uses a 6th Generation Intel Core i5-6500 quad-core processor with a base frequency of 3.20 GHz and a maximum turbo frequency of 3.60 GHz. It has 6 MB of cache and is paired with 8 GB of memory. Graphics are handled by the integrated Intel HD Graphics 530 engine. This combination suits general productivity, web browsing and multi-monitor output via HDMI and two DisplayPort connectors.

Sustained thermal performance

The compact 3.6-inch depth restricts internal airflow compared with larger towers, so the CPU will throttle under prolonged heavy loads to stay within thermal limits. The half-height PCIe x16 and x4 slots only accept low-profile expansion cards, ruling out full-height GPUs or add-in cards. The single M.2 2280 slot and one internal 3.5-inch bay limit storage expansion to one additional drive. Buyers needing continuous high compute throughput or multiple full-height expansion cards should consider a larger chassis.
