DELL QCS1250 SFF desktop PC Core Ultra 7 265K 32GB 512GB NVMe

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.
