Purpose-built business desktop

The OptiPlex All-in-One 7420 integrates a 14-core Intel Core i5-14500 processor with 16 GB of DDR5 memory and a 256 GB M.2 2230 PCIe NVMe SSD Class 35. Intel UHD Graphics 770 drives the 23.8-inch non-touch display. Windows 11 Pro 64-bit is pre-installed. The 160 W power supply supports the entire unit. A wired keyboard and optical mouse are included.

Sustained workload behaviour

The 14-core architecture and 24 MB L3 cache maintain throughput during extended multi-threaded tasks such as spreadsheet modelling or background compilation. DDR5 bandwidth feeds the cores without bottlenecking the integrated graphics. The Class 35 SSD sustains write performance for logging and temporary files. Thermal design within the all-in-one chassis manages heat from the 160 W supply during prolonged operation.

Build and connectivity daily impact

The integrated chassis reduces cable count to a single power cord, simplifying desk deployment. Intel Wi-Fi 6E AX211 2x2 802.11ax and Bluetooth provide wireless flexibility without dongles. The fixed 23.8-inch non-touch panel suits standard viewing distances. Wired USB keyboard and mouse ensure immediate operation. No optical drive is present, so software installs rely on network or USB media.

Questions about this item

How much heat does the 160W power supply generate when the Core i5-14500 runs all day?

The 160W internal supply delivers up to 160W; sustained load on the 14-core 2.60GHz processor will draw a portion of that budget, so the chassis dissipates only what the components consume.

Does the 23.8" non-touch screen need an external keyboard and mouse, or are they included?

A Dell wired multimedia keyboard KB216 and a Dell optical mouse MS116 are bundled in the box, so no separate purchase is required.

Will the Intel UHD Graphics 770 drive a second monitor over the HDMI port if I keep my older display?

The integrated Intel UHD Graphics 770 supports multiple outputs, so an older monitor connected via the available video port will work alongside the built-in 23.8" panel.
