Tower desktop for business and education

The Dell ECT1250 is a tower desktop built around a 24-core Intel Core Ultra 9 285K processor with 36 MB cache and a 5.70 GHz turbo boost. Sixteen gigabytes of DDR5 5600 MHz memory and a 2 TB PCIe NVMe SSD provide fast responsiveness for office applications, classroom workloads and everyday multitasking. Windows 11 Pro is pre-installed and the system includes an Intel AI Boost NPU for on-device AI tasks.

Included wired keyboard, mouse and connectivity

A Dell KB216 wired keyboard and MS116 wired mouse are supplied in the box so the system is ready to use immediately. Wireless connectivity uses a MediaTek Wi-Fi 6 MT7920 2x2 card with MU-MIMO and Bluetooth 5.4, while a gigabit Ethernet port handles wired networks. Video output is provided by one DisplayPort 1.4 and one HDMI 2.1 port for dual-monitor setups.

Memory and storage headroom

The 16 GB DDR5 configuration handles typical business and education workloads comfortably; heavier creative or data-science tasks may benefit from additional memory. The 2 TB NVMe drive offers ample space for documents, applications and local media libraries. Integrated Intel UHD Graphics drives general productivity and dual displays but is not suited for demanding 3D rendering or modern gaming titles.

Questions about this item

How much DDR5 memory can I add to the ECT1250 later?

The board uses DDR5-5600 modules; capacity limits depend on the motherboard which is not detailed in the product data.

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

The 24-core processor can reach 5.70 GHz turbo, so sustained speed will be constrained by the tower's cooling capacity.

How loud and hot does the tower get when it runs all day?

The 12.76 × 6.06 × 11.53 in chassis uses standard Dell thermal design; actual noise and temperature depend on workload and ambient conditions.
