Business All-in-One PC

The Dell OptiPlex 7490 integrates an Intel Core i7-10700 processor, 16 GB DDR4 memory and a 256 GB PCIe SSD behind a 23.8-inch FHD IPS display. Windows 10 Pro is pre-installed for immediate deployment in office environments.

Thermals and Power

A 160 W internal power supply drives the 8-core CPU and integrated Intel UHD Graphics 630 without a discrete GPU. The all-in-one chassis handles typical business workloads at moderate fan noise levels.

Build Integration

The unit includes 10/100/1000 Mbps LAN, 802.11ax wireless and Bluetooth for flexible connectivity. A built-in webcam supports video conferencing while the non-touch screen keeps the desktop footprint minimal. Buyers needing discrete graphics expansion or additional internal drive bays should consider a separate tower configuration.

Questions about this item

How is the 256 GB PCIe SSD installed in the OptiPlex 7490 and what step do people miss?

The drive is factory-fitted inside the sealed chassis; the step people miss is not opening the unit, because the all-in-one design has no user-accessible drive bay.

What maintenance or replacement will the 16 GB DDR4 memory need later?

The memory is soldered to the mainboard, so it cannot be upgraded or replaced; any capacity increase requires a full system change.

What limit appears first on the 160 W power supply during sustained loads?

The 160 W adapter caps total system draw, so the Intel Core i7-10700 will throttle once combined CPU and display demand reaches that ceiling.
