DELL KH0K4 Pro Slim QCS1255 desktop PC AMD Ryzen 7 PRO 8700G 16GB 512GB Windows 11 Pro

Slim desktop for everyday workloads

The DELL Pro Slim QCS1255 is a compact desktop PC built around an AMD Ryzen 7 PRO 8700G processor with a base frequency of 4.2 GHz and a turbo frequency of 5.1 GHz. It ships with 16GB DDR5 memory running at 4800 MT/s and a 512GB SSD. Windows 11 Pro is pre-installed. Integrated graphics drive displays via DisplayPort and HDMI. Gigabit Ethernet provides wired networking.

Capacity and headroom

The 16GB DDR5 configuration handles typical office multitasking, web browsing and light content creation without paging. The 512GB SSD offers enough space for the operating system, applications and a moderate working set of files. Users working with large media libraries, virtual machines or extensive local datasets will find the storage capacity limiting. Memory is not user-expandable in this slim chassis, so the 16GB ceiling is fixed.

Thermals, noise and power draw

The slim form factor measuring 3.74 inches wide, 11.54 inches deep and 11.95 inches high relies on a compact internal cooling solution tuned for the integrated graphics design. Under sustained load the processor will reach its thermal limits sooner than in a tower chassis, causing the fan to spin faster and produce audible airflow noise. At idle or during light productivity tasks the system runs quietly. Power draw scales with the 8700G workload profile rather than a discrete GPU.
