DELL OptiPlex 7040 SFF i7-6700 3.4GHz 8GB DDR4 512GB NVMe desktop PC

Business small-form-factor desktop

The Dell OptiPlex 7040 SFF packs a 64-bit quad-core Intel i7 6700 processor running at 3.4 GHz into a slim chassis designed for office environments. With 8 GB of DDR4 memory and a 512 GB NVMe PCIe M.2 SSD, it handles everyday productivity tasks and fast boot cycles without a full-size tower footprint. Windows 10 Pro comes pre-installed and activated, so the system is ready for domain join or local administration straight out of the box.

Thermals and power in daily use

The small form factor relies on integrated Intel HD 530 graphics and the 8 MB L3 cache to keep heat output modest during typical business workloads. A single internal fan manages airflow across the Q170 chipset and processor, keeping noise low enough for open-plan desks while drawing only the power needed for routine document, browser and video-conferencing sessions.

Build integration and connectivity

Dual DisplayPort and one HDMI 1.4 output drive modern monitors, though legacy VGA or DVI screens require an active adapter. Six USB 3.0 and four USB 2.0 ports provide ample peripheral bandwidth, while Gigabit Ethernet and a native serial port cover wired networking and specialised equipment. The compact case leaves desk space free but offers no room for a discrete graphics card or additional full-height expansion cards.
