DELL OptiPlex 7770 27" FHD i5-9500 64 GB DDR4 256 GB M.2 SSD + 1TB HDD all-in-one PC

Business all-in-one with 27-inch display

The Dell OptiPlex 7770 integrates a 27-inch Full HD IPS InfinityEdge panel with a 9th Gen Intel hexa-core i5-9500 processor, 64 GB of DDR4 memory and dual storage comprising a 256 GB M.2 SSD plus a 1 TB hard drive. Windows 10 Pro is pre-installed alongside a USB keyboard and mouse. The compact chassis suits office desks that need a tidy, single-cable workstation.

Memory capacity and type fixed at 64 GB DDR4 SODIMM

The system ships with 64 GB of DDR4 SODIMM memory installed in a 204-pin form factor, which matches the supplier specification for this configuration. No other memory generation or capacity is present in this unit, so buyers requiring a different amount or a newer DDR standard must select another model. Integrated Intel UHD Graphics 630 handles the display output.

Simple desk setup with limited internal access

Placing the all-in-one on a desk and connecting power, network and peripherals completes the installation because the keyboard, mouse and operating system are already provided. Internal upgrades are restricted by the sealed all-in-one design, so adding storage or changing memory later is not practical. Buyers who need user-serviceable components or discrete graphics should choose a separate tower and monitor.
