Dell QCS1250 SFF business desktop

The Dell QCS1250 is a small-form-factor desktop built around an Intel Core Ultra 9 285K processor with 24 cores and a 5.7 GHz maximum turbo frequency. It ships with 16 GB of DDR5 5600 MHz memory and a 512 GB NVMe drive. Windows 11 Pro is pre-installed, and a wired keyboard and mouse are included in the box.

Sustained workload behaviour

The 24-core CPU can reach 5.7 GHz on short bursts, while the integrated NPU delivers 13 TOPS for AI-accelerated tasks. Integrated Intel UHD Graphics 770 drives one HDMI 2.1 and one DisplayPort 1.4a output for dual-display productivity. The compact 95 mm-wide chassis relies on internal airflow to manage thermals during extended compute sessions.

Installation and common issues

The system arrives fully assembled with the operating system already configured, so first boot only requires power, display and network connections. Front-panel ports include two USB 2.0, one USB 3.2 Gen 1 Type-A and one Type-C plus a global headset jack for quick peripheral access. Buyers who want more storage or discrete graphics will find no spare drive bays or expansion slots inside the slim enclosure.

Questions about this item

How much power does the Core Ultra 9 285K draw when the system runs all day?

The processor has a base frequency of 3.70 GHz and can boost to 5.7 GHz with 24 cores and 36 MB cache, so sustained load will draw more power than idle use.

What display cable do I need to connect a monitor to the HDMI 2.1 (TMDS) or DisplayPort 1.4a (HBR2) ports?

You must supply a monitor and the matching HDMI or DisplayPort cable; the desktop includes only the ports, not the cable.

Will my older USB 2.0 peripherals work with the front and rear USB 2.0 (480 Mbps) ports?

Yes, the four USB 2.0 ports at 480 Mbps are backward compatible with older USB 2.0 devices such as keyboards, mice and printers.
