DELL Pro Slim QCS1250 SFF Desktop PC Intel Core Ultra 9 285 24-Core 16GB 512GB NVMe

Compact desktop for business users

The Dell Pro Slim QCS1250 is a small-form-factor desktop built around an Intel Core Ultra 9 285 processor with 24 cores and a 36MB cache. It ships with 16GB of DDR5 5600 MHz memory and a 512GB NVMe SSD. Windows 11 Pro is pre-installed, and a wired keyboard and mouse are included in the box. Integrated Intel UHD Graphics 770 drives displays through HDMI 2.1 and DisplayPort 1.4a outputs.

Thermals and power in daily use

The compact chassis measures 303.50 mm tall, 95 mm wide and 293 mm deep, weighing 3.90 kg. Its small internal volume limits airflow compared with larger towers, so sustained heavy workloads will raise internal temperatures and fan noise more quickly. The 24-core processor has a base frequency of 2.50 GHz and can boost up to 5.6 GHz, increasing power draw under load. Gigabit Ethernet provides wired connectivity without adding wireless heat.

Included peripherals and software impact

The bundled Dell KB216 wired keyboard and wired mouse connect via USB, removing the need for separate purchases and reducing desk clutter. Windows 11 Pro enables business-management features such as BitLocker and Remote Desktop out of the box. Front-panel ports include two USB 2.0, one USB 3.2 Gen 1 Type-A and one Type-C at 5 Gbps, plus a global headset jack for quick accessory access.
