Dell Pro Slim QCS1250 SFF desktop PC

This small-form-factor desktop ships new with an Intel Core Ultra 7 265K 20-core processor reaching 5.5 GHz, 32 GB DDR5 memory at 5600 MHz and a 1 TB NVMe PCIe SSD. It targets business and education buyers who need a compact Windows 11 Pro workstation with integrated Intel UHD Graphics 770 and a 13 TOPS NPU for local AI workloads.

Included keyboard, mouse and front-panel ports

A Dell KB216 wired keyboard and wired mouse are supplied, removing the need for separate input-device purchases. The front panel adds one USB 3.2 Gen 1 Type-C port, one USB 3.2 Gen 1 Type-A port, two USB 2.0 ports and a global headset jack for quick peripheral access.

Check monitor inputs and rear-port layout before

Video output relies on one HDMI 2.1 TMDS port and one DisplayPort 1.4a HBR3 port on the rear; verify your display matches these interfaces. Rear connectivity also provides two USB 3.2 Gen 1 ports, two USB 2.0 ports and a single RJ45 Ethernet jack, so confirm cable reach and port count suit your desk setup.

Questions about this item

Will the 32 GB DDR5 5600 MHz memory need replacing if I run heavier workloads later?

The board ships with 32 GB of DDR5 5600 MHz installed; adding more requires opening the chassis and fitting compatible DDR5 modules into any free slots.

What limit appears first when the Core Ultra 7 265K runs at 5.5 GHz Turbo for long periods?

The 20-core processor will hit its thermal ceiling before the 30 MB Smart Cache or the 1 TB PCIe NVMe M.2 SSD become bottlenecks.

How loud and hot does the 3.74-inch wide SFF case get when the system runs all day?

The compact 95 mm wide chassis uses a single system fan that stays near 30 dBA at idle and rises to the mid-range under full load while the 265 K processor draws its rated power.
