Compact Power for Business Users

The Dell Pro Slim QCS1250 is a small-form-factor desktop built around a 24-core Intel Core i9-14900K processor. It targets offices and education buyers who need high single-thread speed in a chassis only 95 millimetres wide. Integrated Intel UHD Graphics 770 handles standard productivity displays without a discrete card. Buyers who need dedicated GPU performance for rendering or gaming should look elsewhere.

24-Core CPU with 6.0 GHz Boost

The deciding specification is the Intel Core i9-14900K running at 3.20 GHz base with Turbo Boost up to 6.0 GHz and 36 MB smart cache. Its LGA 1700 socket and 14th-generation architecture deliver the multi-thread throughput that justifies the i9 tier for compile workloads and heavy multitasking. If your software scales past 24 threads or demands certified workstation graphics, this processor alone will not cover the gap.

Included Input Kit and Pro OS

A Dell KB216 wired keyboard and a wired mouse ship in the box, so the system is ready for deployment without extra peripherals. Windows 11 Pro 64-bit is pre-installed, providing BitLocker, Remote Desktop and domain-join features that home editions lack. The 2 TB PCIe NVMe M.2 drive and 32 GB of DDR5 5600 MHz memory leave no immediate upgrade requirement for typical knowledge-worker workloads.

Questions about this item

How does the 6.0 GHz turbo speed behave inside this small-form-factor chassis?

The Core i9-14900K can reach 6.0 GHz on active cores, but the compact 303.5 mm high case limits sustained all-core boost; expect clocks to settle lower under prolonged heavy loads.

What does the DisplayPort 1.4a and HDMI 2.1 pair on the integrated UHD 770 actually support?

Both ports run from the same iGPU; they can drive two 4K displays at 60 Hz, but total bandwidth is shared, so higher refresh rates on one screen reduce options on the other.

Will a full-height add-in card fit in the 95 mm wide Pro Slim case?

The chassis is only 95 mm wide and uses a low-profile bracket; standard full-height cards will not fit — only low-profile or riser-mounted half-height cards are compatible.
