Business all-in-one with 27-inch display

The DELL OptiPlex 7770 is a 27-inch all-in-one PC built for business users who want a single desktop unit. It combines a 9th Gen Intel Octa-Core i7-9700 processor running at 3.0GHz with 64GB of DDR4 memory and a dual-drive layout of 256GB M.2 SSD plus 1TB hard drive. Windows 11 Pro is pre-installed.

Suits office teams needing simple deployment

This system suits offices that value quick setup, integrated webcam and microphone for video calls, and a clutter-free desk with included USB keyboard and mouse. Buyers who need discrete graphics performance for 3D rendering or gaming workloads should look elsewhere, as the platform relies on integrated Intel UHD Graphics 630.

64GB RAM and mixed storage for multitasking

The 64GB DDR4 capacity handles heavy multitasking, large spreadsheets and multiple browser tabs without paging. The 256GB M.2 SSD provides fast boot and application launch, while the 1TB hard drive stores archives and media. Workloads that demand sustained GPU compute or more than 64GB of memory will exceed the available headroom.

Questions about this item

Does this all-in-one need any external parts such as a monitor or power brick to operate?

Can I keep using my existing USB 2.0 flash drives and older USB hard drives with the ports on this OptiPlex 7770?

Yes. The system provides three USB 3.1 Gen 1 Type-A ports, two USB 3.1 Gen 2 Type-A ports and one USB Type-C Gen 2 port, all of which are backward compatible with USB 2.0 and USB 3.0 devices.

How can I confirm the 64 GB of DDR4 memory and the dual-drive storage are recognised correctly after first boot?

Open Windows Settings → System → About to see the installed RAM listed as 64 GB, then open File Explorer and verify that both the 256 GB M.2 SSD and the 1 TB hard drive appear with their full capacities.
