DELL QCS1250 SFF Desktop PC Intel Core Ultra 7 265K 16GB 512GB NVMe

Dell QCS1250 SFF business desktop

The Dell QCS1250 is a small-form-factor desktop built around an Intel Core Ultra 7 265K processor with 20 cores and a 13 TOPS NPU. It ships with 16 GB of DDR5 memory and a 512 GB NVMe solid-state drive. Windows 11 Pro is pre-installed and a wired keyboard and mouse are included. The compact chassis suits office desks and education deployments where space is limited.

Capacity and headroom

Sixteen gigabytes of DDR5 memory handles typical productivity suites, video conferencing and browser-heavy workloads without swapping. The 512 GB NVMe drive provides fast boot and application launch times for standard business datasets. Memory-intensive tasks such as large-scale data analysis, virtualisation or local AI model training will exceed the installed capacity. The integrated Intel UHD Graphics 770 supports dual-display output via HDMI 2.1 and DisplayPort 1.4a but lacks discrete GPU performance for 3D rendering or GPU compute.

Thermals, noise and power

The slim 95 mm-wide enclosure relies on internal airflow to cool the 20-core processor at sustained loads. Under typical office use the system runs quietly, with fan noise rising only during prolonged turbo operation up to 5.5 GHz. Power draw scales with processor utilisation and remains within the limits of the supplied internal power supply. Buyers needing continuous heavy compute or silent operation in noise-sensitive studios should consider larger workstations with expanded cooling.
