Dell Pro Slim QCS1250 SFF desktop PC
This small-form-factor business desktop ships new with an Intel Core Ultra 7 265K processor, 32GB of DDR5 5600 MHz memory and a 512GB NVMe SSD. Windows 11 Pro is pre-installed and a wired keyboard and mouse are included. Integrated Intel UHD Graphics 770 drives one HDMI 2.1 and one DisplayPort 1.4a output for dual-monitor setups. The compact black chassis measures 11.95 x 3.74 x 11.54 inches and weighs 8.61 lb.
Check your setup before ordering
The system uses an LGA 1851 socket so the motherboard is not user-upgradable to other CPU families. Only two DDR5 slots are populated at 32GB total; verify whether your workload needs more memory before purchase. A single M.2 NVMe slot holds the 512GB drive; additional internal storage requires a 2.5-inch bay or external solution. Video outputs are limited to the integrated graphics ports listed; no discrete GPU can be fitted in the slim chassis.
Thermals noise and power in normal use
The 20-core processor reaches up to 5.5 GHz turbo within the SFF thermal envelope; expect fan activity to rise under sustained multi-core loads. Idle noise is low in typical office environments thanks to the compact 1250 chassis design. The 13 TOPS NPU handles AI-accelerated tasks without engaging the main cores heavily, helping keep power draw moderate. Integrated graphics share system memory, so heavy video playback will increase RAM bandwidth usage but not add a separate heat source.

Questions about this item
Does the Dell QCS1250 SFF come with a monitor or do I need to buy one separately?
The box includes the desktop, a Dell KB216 wired keyboard and a Dell wired mouse. A monitor is not included and must be purchased separately.
The Core Ultra 7 265K has 20 cores and a 5.5 GHz turbo — which workloads actually use that?
The 20-core design with 30 MB cache and 5.5 GHz turbo boost handles multi-threaded business applications, data analysis and AI-assisted tasks accelerated by the 13 TOPS NPU.
Will the integrated Intel UHD Graphics 770 drive two 4K displays from the HDMI 2.1 and DisplayPort 1.4a outputs?
Yes. The HDMI 2.1 (TMDS) and DisplayPort 1.4a (HBR2) ports both support 4K resolution, so you can run dual 4K monitors without a discrete graphics card.
