Compact SFF desktop

The Dell OptiPlex 9800 small-form-factor desktop runs Windows 11 Pro on an Intel Core i5-6500 dual-core processor at 3.2 GHz. Integrated Intel HD Graphics handles everyday display tasks without a separate card. Eight gigabytes of memory and a 256 GB SSD provide a responsive base for office applications and light multitasking.

Build integration

The SFF chassis fits on or under a desk and leaves room for standard peripherals. Two memory slots support expansion up to 32 GB when workloads grow. A USB Wi-Fi adapter supplies wireless connectivity without occupying an internal slot. DisplayPort outputs drive external monitors for multi-screen productivity.

Thermals and power

The compact enclosure uses a low-profile cooling solution tuned for the 65 W processor. Fan noise stays low during typical office loads such as document editing, web browsing and video playback. Power draw remains modest, keeping energy costs predictable for daily business use.

Questions about this item

What thermal limit appears first when the Intel Core i5-6500 runs at 3.2 GHz continuously?

The dual-core i5-6500 reaches its package power ceiling before the small-form-factor chassis can move more heat, so sustained clocks drop to stay within the rated TDP.

How loud and hot does the 9800 SFF get during an all-day workload?

The integrated Intel HD Graphics and 65 W-class CPU keep fan noise to a low hum and case temperatures warm but comfortable to touch after hours of use.

Which display cable must I already own to connect a monitor to the DisplayPorts?

A standard DisplayPort-to-DisplayPort cable is required; the unit ships with only the USB Wi-Fi adapter for wireless networking.
