Overview

The Dell OptiPlex 7400 All-in-One consolidates a full desktop computing setup into a single, streamlined unit anchored by a 23.8-inch Full HD display. The screen features wide viewing angles, an anti-glare coating, and a low blue light filter — a combination that prioritizes visual comfort for professionals who spend long hours at their desk. Under the hood, a 12th Generation Intel Core i5-12500 processor with six cores and boost speeds up to 4.60 GHz provides responsive performance for business applications, multitasking, and video conferencing. Paired with 16GB of DDR4 RAM, the system handles typical office workloads without hesitation.

Storage comes in the form of a 256GB PCIe M.2 SSD, which ensures fast boot times and snappy application launches, though capacity-conscious users may need to supplement with external or network storage. Wireless connectivity is a standout feature: Intel Wi-Fi 6E (AX211) with 6GHz band support and Bluetooth 5.2 provide access to the latest wireless standards, reducing congestion and improving throughput in dense office environments. An integrated FHD RGB webcam and microphone make the OptiPlex 7400 video-conference-ready without additional peripherals. Dell includes a wired MS116 optical mouse and US English keyboard in the box, and the system ships with Windows 11 Pro along with Dell's Onsite/In-Home and Accidental Damage Service for added protection.
