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.

Questions about this item

Will the Pro Slim QCS1255 fit on the same shelf as my older tower given its depth of 11.54 Inch?

The system depth is 11.54 Inch, so it will fit on any shelf that accommodates at least that measurement.

How can I confirm the AMD Ryzen 7 PRO 8700G is running at its 5.1 GHz turbo after setup?

Open Task Manager in Windows 11 Pro, select the Performance tab, and watch the CPU clock reach 5.1 GHz under load.

What cables and accessories are included with the KH0K4 besides the 512GB SSD and 16GB DDR5 already installed?

The box contains the desktop unit and a power cord; a monitor, keyboard, mouse and any display cables are sold separately.
