Pro Slim QCS1250 SFF
The Dell Pro Slim QCS1250 is a small-form-factor desktop built around a 24-core Intel Core i9-14900K processor reaching 6.0 GHz. It ships with 32 GB of DDR5 memory at 5600 MHz and a 1 TB PCIe NVMe M.2 drive. Windows 11 Pro is pre-installed, making the system ready for business or education workloads immediately.
Thermals and power
The 11.95 by 3.74 by 11.54 inch chassis weighs 8.61 lb and houses the 24-core CPU with integrated Intel UHD Graphics 770. No discrete graphics card is present, so the cooling solution handles only the processor and platform heat. Gigabit Ethernet provides wired network connectivity without additional wireless hardware.
Included peripherals
A Dell KB216 wired keyboard and a Dell wired mouse connect via USB Type-A ports. The front panel offers two USB 2.0 ports, one USB 3.2 Gen 1 Type-A port and one USB 3.2 Gen 1 Type-C port plus a global headset jack. Rear video outputs comprise one HDMI 2.1 and one DisplayPort 1.4a for dual-display support.

Questions about this item
How do I install the DDR5 memory in the QCS1250 SFF, and what step is often missed?
Open the chassis, align the notch on the DDR5 module with the slot key, press firmly until the retention clips click, then verify 5600 MHz operation in BIOS — the step often missed is seating the module fully so both clips engage automatically.
What maintenance or replacement will the QCS1250 SFF need over time?
The 1 TB NVMe SSD has a finite write endurance; plan to replace it once the SMART health indicator approaches its rated TBW limit, and clean dust from the compact 95 mm wide chassis vents annually to maintain airflow.
What limit appears first when the Core i9-14900K runs sustained loads in this SFF?
The 24-core processor can hit 6.0 GHz turbo, but the small 3.74 in. wide enclosure restricts cooler capacity, so thermal throttling under prolonged all-core workloads is the first limit you will encounter.
