DELL OptiPlex 7040 SFF i5-6500 3.2 GHz 8 GB DDR4 256 GB SSD desktop PC

Dell OptiPlex 7040 SFF business desktop

The Dell OptiPlex 7040 SFF is a small-form-factor business desktop powered by a 64-bit quad-core Intel Core i5-6500 processor running at 3.20 GHz with 6 MB L3 cache. It comes with 8 GB of DDR4 memory and a 256 GB SSD for the operating system and applications. Integrated Intel HD Graphics 530 drives up to three displays via two DisplayPort outputs and one HDMI port. The system includes a DVD-ROM optical drive and ships with Windows 10 Home pre-installed.

Check video outputs and wireless needs

This unit provides two DisplayPort connectors and one HDMI port but has no VGA or DVI outputs, so older monitors will require an adapter or a different cable. Gigabit Ethernet at 10/100/1000 Mbps is built in, while Wi-Fi is not included and must be added separately if wireless networking is required. Six USB 3.0 ports and four USB 2.0 ports are available for peripherals, and a single serial port is present for legacy devices. No keyboard, mouse or monitor is supplied in the box.

Thermals noise and power in normal use

The compact SFF chassis uses integrated graphics and a 65 W-class processor, so heat output and fan noise stay low during typical office workloads such as document editing, web browsing and video playback. Power draw remains modest because the system lacks a discrete graphics card and relies on the 256 GB SSD rather than mechanical drives. The included DVD-ROM adds negligible thermal load when not reading discs. Overall the platform runs quietly and cool enough for continuous operation in a quiet office environment.
