Business all-in-one with 27-inch FHD display

The Dell OptiPlex 7770 integrates a 27-inch IPS InfinityEdge panel at 1920 x 1080 resolution with a 9th Gen Intel Hexa-Core i5-9500 processor running at 3.0GHz up to 4.40GHz. It ships with 32GB DDR4 SODIMM memory and a 2.5-inch 256GB SSD. Windows 10 Pro is pre-installed alongside a USB keyboard and mouse.

Passive cooling profile for office use

Intel UHD Graphics 630 handles the display output without a discrete GPU, keeping thermal output and acoustic levels low in typical business workloads. The integrated design consolidates compute and display into one chassis, reducing cable count and overall power draw compared to separate tower and monitor setups. Gigabit Ethernet, Wi-Fi and Bluetooth 5 provide connectivity.

Replaces separate tower and monitor combos

This unit suits buyers who want a single-cable desktop for general productivity, video calls via the integrated HD TrueVision webcam, and multi-monitor expansion through DisplayPort and USB Type-C Gen 2. It does not serve workloads needing discrete graphics, higher storage capacity than 256GB, or memory beyond 32GB DDR4. Buyers requiring those capabilities should consider a modular tower configuration.

Questions about this item

How do I install the 2.5-inch 256 GB SSD in this OptiPlex 7770 all-in-one?

The 2.5-inch 256 GB SSD is already installed from the factory; no user installation is required for the supplied drive.

What memory upgrades will this system need later, and what type do I buy?

It uses 32 GB of DDR4 SODIMM memory in 204-pin slots and supports up to 64 GB total if you add or replace modules later.

What is the first limit I will hit when the i5-9500 runs at its 4.40 GHz turbo for a long time?

The integrated Intel UHD Graphics 630 shares system memory and thermal headroom with the CPU, so sustained turbo loads will throttle graphics and processor performance first.
