27-inch business all-in-one

This 27-inch OptiPlex 7770 combines a 1920 x 1080 IPS display with a 9th Gen Intel Octa-Core i7-9700 processor running at 3.0 GHz up to 4.70 GHz. Eight gigabytes of DDR4 memory and dual storage — a 128 GB M.2 SSD plus a 1 TB hard drive — come standard. Windows 10 Pro is pre-installed on a system built for office environments.

Included peripherals and connectivity

A USB keyboard and mouse are bundled so the unit is ready to deploy. Wireless connectivity uses integrated Wi-Fi and Bluetooth 5. Wired ports include three USB 3.1 Gen 1, one USB Type-C Gen 2, two USB 3.1 Gen 2, DisplayPort and a 3-in-1 SD card reader. An HD TrueVision webcam and microphone handle video calls without extra hardware.

Suited for general office deployment

The configuration fits workers who need a compact desktop with a built-in screen, webcam and wired Gigabit Ethernet for standard productivity apps. Buyers who require discrete graphics performance, more than 8 GB of memory out of the box, or a newer Windows licence should evaluate other options.

Questions about this item

Can the 8 GB DDR4 SODIMM be upgraded to 64 GB later?

The board supports up to 64 GB of DDR4 across its SODIMM slots, so the installed 8 GB module can be replaced or supplemented with higher-capacity sticks.

Which component reaches its limit first during long workloads — the Intel UHD Graphics 630 or the i7-9700 CPU?

The integrated Intel UHD Graphics 630 will hit its performance ceiling before the eight-core i7-9700 during sustained graphics-heavy tasks.

How loud and hot does the 27" all-in-one get when it runs all day with the i7-9700 and dual drives?

The slim chassis relies on internal fans to cool the i7-9700 and both drives; expect audible fan noise and warm exhaust after extended full-load operation.
