Ready-to-use business all-in-one

This DELL OptiPlex 7770 arrives with a 27 inch 1920 x 1080 IPS display, a 9th Gen Intel six-core i5-9500 running at 3.0 GHz, 8 GB of DDR4 memory and a 128 GB 2.5 inch SSD. Windows 10 Pro is pre-installed along with a USB keyboard and mouse so the system is operational straight from the box.

Bundled peripherals and connectivity

The included keyboard and mouse remove the need for separate input devices. A 720p HD TrueVision webcam and microphone support video calls without extra hardware. Wireless connectivity uses Bluetooth 5 and integrated Wi-Fi. Wired ports comprise 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.

Compatibility checks before ordering

The 128 GB SSD offers limited space for large local datasets so users with heavy storage needs should plan an upgrade or external drive. Integrated Intel UHD Graphics 630 handles office workloads but is not suited to demanding 3D or video tasks. Memory uses 204-pin SODIMM DDR4 modules if a future capacity increase is required. The unit ships with Windows 10 Pro; verify that your software environment supports this operating system.

Questions about this item

How easy is it to upgrade the 8 GB DDR4 memory in this OptiPlex 7770?

The system uses 204-pin SODIMM DDR4 slots and the manufacturer highlights support up to 64 GB, so adding or replacing modules is straightforward.

Will the Intel UHD Graphics 630 throttle during long video-editing sessions?

Sustained heavy GPU loads on the integrated 630 graphics will hit thermal limits before the 6-core i5-9500 reaches its 4.40 GHz turbo ceiling.

How loud does the cooling fan get when the i5-9500 runs at 4.40 GHz all day?

Under continuous max-turbo workloads the fan spins up to an audible but office-tolerable level; typical business tasks keep it near idle speed.
