SFF desktop with Core Ultra 9 285K

The Dell Pro Slim QCS1250 is a small-form-factor business desktop built around a 24-core Intel Core Ultra 9 285K processor. It ships with 16GB of DDR5 5600 MHz memory and a 256GB PCIe NVMe M.2 solid-state drive. Windows 11 Pro is pre-installed and a wired keyboard and mouse are included in the box.

Upgrade from older SFF workstations

This system replaces legacy small-form-factor PCs that rely on previous-generation processors and slower storage interfaces. The jump is worthwhile when workloads demand the 24-core architecture, 36MB Smart Cache and turbo frequencies up to 5.7 GHz for multi-threaded applications. The integrated NPU rated at 13 TOPS adds on-device AI acceleration that older platforms lack.

Suited for office and education deployments

Buyers who need a compact, managed fleet device with modern connectivity — HDMI 2.1, DisplayPort 1.4a and Gigabit Ethernet — will find this configuration fits standard desk spaces. It is not intended for users who require discrete graphics performance, additional internal drive bays or expansion slots beyond the provided USB complement.

Questions about this item

What are the exact height, width and depth of the SFF chassis?

The case measures 11.95 in height, 3.74 in width and 11.54 in depth, so verify your desk or rack clearance before ordering.

Which screw or latch secures the side panel for internal access?

Remove the single thumbscrew at the rear edge, then slide the panel toward the back to release it; forgetting the slide step is the common mistake.

When should the 256 GB PCIe NVMe M.2 SSD be replaced?

Plan a swap when SMART health drops below 80 percent or write endurance nears the rated TBW, typically after several years of heavy workloads.
