Small-form-factor business desktop

The Dell QCS1250 is a 2025 small-form-factor desktop built around a 24-core Intel Core Ultra 9 285 processor with 36MB cache and a 13 TOPS NPU. It ships with 32GB of DDR5 5600 MHz memory and a 512GB NVMe SSD. Integrated Intel UHD Graphics 770 drives one HDMI 2.1 and one DisplayPort 1.4a output. Windows 11 Pro is pre-installed, and a wired keyboard and mouse are included.

Sustained-load behaviour

The 2.50 GHz base clock can reach 5.6 GHz under turbo, while the 13 TOPS NPU handles AI-accelerated workloads without a discrete graphics card. Integrated UHD 770 graphics share system memory, so extended 3D or compute tasks will be limited by the 32GB DDR5 pool and the compact chassis airflow. Gigabit Ethernet provides a stable wired link for long-running data transfers or remote management sessions.

Installation and common issues

The unit measures 3.74 inches wide, 11.54 inches deep and 11.95 inches high, fitting tight desk spaces or VESA mounts. 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. Rear I/O adds two more USB 2.0, two USB 3.2 Gen 1, display outputs and RJ45. Builders who need more storage bays, a second graphics card or additional PCIe slots will find the small-form-factor chassis restrictive.

Questions about this item

How loud or hot does the Core Ultra 9 285 get when the Dell QCS1250 runs all day?

The 24-core Core Ultra 9 285 reaches 5.6 GHz turbo and includes a 13 TOPS NPU; the small-form-factor chassis measures 11.95 in high by 3.74 in wide by 11.54 in deep and weighs 8.61 lb, so airflow is managed within that compact volume.

What display cable must I already own to use the integrated Intel UHD Graphics 770?

The rear panel provides one HDMI 2.1 (TMDS) port and one DisplayPort 1.4a (HBR2) port; have a matching cable ready for the monitor you plan to connect.

Will my older USB 2.0 peripherals work with the front and rear ports on this desktop?

Yes — the front has two USB 2.0 ports and the rear has two more USB 2.0 ports, all running at 480 Mbps, so legacy keyboards, mice or drives plug in directly.
