Dell Pro Slim QCS1250 SFF desktop PC

This small-form-factor desktop runs an Intel Core Ultra 9 285K processor with 24 cores, 36MB cache and a 13 TOPS NPU. It ships with 32GB DDR5 5600 MHz memory and a 256GB PCIe NVMe M.2 solid-state drive. Windows 11 Pro 64-bit is pre-installed. Integrated Intel UHD Graphics 770 drives the video outputs.

Included keyboard and mouse change daily use

A Dell KB216 wired keyboard and a Dell wired mouse are supplied in the box. The front panel adds a USB 3.2 Gen 1 Type-C port, a USB 3.2 Gen 1 Type-A port, two USB 2.0 ports and a global headset jack. Rear I/O provides two more USB 3.2 Gen 1 ports, two USB 2.0 ports, HDMI 2.1, DisplayPort 1.4a and gigabit Ethernet.

Suits offices that need AI-ready multi-threaded

The 24-core CPU and on-board NPU handle heavy productivity and local inference workloads in a chassis only 95 mm wide. Buyers who require discrete graphics, additional internal drive bays or more than 32GB of memory should consider a larger tower platform.

Questions about this item

Will the 256GB NVMe SSD need replacing if storage fills up?

The 256GB NVMe SSD can be swapped for a larger PCIe M.2 drive when more space is required.

What limits the Core Ultra 9 285K during long heavy workloads?

The 24-core CPU turbo boosts to 5.7GHz; sustained performance will be constrained by the small-form-factor cooling capacity.

How loud and hot does the SFF chassis get when running all day?

The 3.74in wide chassis uses a compact fan; expect audible airflow and warm exhaust under continuous load.
