Dell Pro Slim QCS1250 SFF

This Dell Pro Slim QCS1250 is a small-form-factor desktop built around a 24-core Intel Core i9-14900K processor that reaches 6.0 GHz. It ships with 16GB of DDR5 5600 MHz memory and a 4TB PCIe NVMe M.2 solid-state drive. Windows 11 Pro is pre-installed and a wired keyboard plus mouse are included in the box. Integrated Intel UHD Graphics 770 drives one HDMI 2.1 and one DisplayPort 1.4a output.

Who this suits and who should look elsewhere

The system suits offices, education deployments or home workers who need strong multi-threaded CPU performance in a compact 95 mm-wide chassis with abundant fast storage. Buyers who require a discrete graphics card for 3D rendering, gaming or GPU compute workloads should consider a larger tower that can accommodate a dedicated GPU and its power requirements.

The spec that decides fit

The single specification that determines whether this desktop is the right part is the integrated Intel UHD Graphics 770, which limits visual workloads to desktop productivity, video playback and light creative tasks without a discrete GPU option.

Questions about this item

What display cable do I need to connect a monitor to the HDMI 2.1 port on the Intel UHD Graphics 770?

A standard HDMI cable compatible with the HDMI 2.1 (TMDS) output on the rear panel will carry video from the integrated graphics to your monitor.

Will my existing USB 2.0 keyboard and mouse work with the four USB 2.0 ports on this desktop?

Yes, the four USB 2.0 (480 Mbps) ports — two on the front and two on the rear — are fully backward-compatible with USB 2.0 peripherals.

How can I verify the Intel Core i9-14900K is running at its 6.0 GHz turbo frequency under load?

Open Task Manager in Windows 11 Pro, select the Performance tab, choose CPU, and watch the live speed readout while running a demanding workload.
