All-in-One with 27" IPS display

The Dell OptiPlex 7770 combines a 27-inch 1920 x 1080 IPS InfinityEdge panel with a 9th Gen Intel Hexa-Core i5-9500 processor. It ships with 16 GB DDR4 SODIMM memory and a 2.5-inch 512 GB SSD. Windows 10 Pro is pre-installed alongside a USB keyboard and mouse.

Sustained workloads on six cores

The i5-9500 runs at 3.0 GHz with a turbo frequency up to 4.40 GHz across six cores and six threads. Integrated Intel UHD Graphics 630 handles everyday visual output. The all-in-one chassis manages thermal load for continuous business applications without discrete graphics.

Simple setup with integrated peripherals

A single power cable powers the entire unit, while the included USB keyboard and mouse connect immediately. The 204-pin SODIMM slots and 2.5-inch drive bay allow memory and storage upgrades, though accessing them requires removing the rear cover. Buyers needing discrete GPU performance or more than 64 GB DDR4 should consider a tower workstation.

Questions about this item

How loud and hot does the i5-9500 hexa-core get during all-day office use?

The integrated Intel UHD Graphics 630 and six-core processor handle typical business tasks without demanding high fan speeds, so noise and heat stay modest in a 27" all-in-one chassis.

Which peripherals and cables must I already have to start working with this OptiPlex 7770?

A USB keyboard and mouse are included in the box, and the 27" 1920 x 1080 display is built in, so no external monitor, video cable or separate input devices are required.

Can I keep using my older DisplayPort monitor and USB 3.0 accessories alongside the USB 3.1 Gen 1 and Gen 2 ports on this unit?

Yes, the DisplayPort output and USB 3.1 Gen 1 and Gen 2 ports are backward compatible with DisplayPort 1.2 screens and USB 3.0 devices, so legacy peripherals will work without adapters.
