Tower desktop for business and education

The Dell ECT1250 is a tower desktop built around an Intel Core Ultra 9 285 processor with 24 cores and a 36MB L3 cache. It ships with 48GB of DDR5 5600 MHz memory and a 512GB NVMe SSD. The NVIDIA GeForce RTX 3050 6GB GDDR6 graphics card drives displays through DisplayPort 1.4, HDMI 2.1 and DVI outputs. Windows 11 Home is pre-installed and a wired keyboard and mouse are included.

Sustained workload behaviour

The 24-core CPU runs at a 2.5 GHz base frequency and can reach 5.60 GHz with Turbo Boost, while the integrated Intel AI Boost NPU handles AI-accelerated tasks. The RTX 3050 provides a dedicated 6GB GDDR6 frame buffer for graphics workloads. DDR5 5600 MHz memory feeds both compute and graphics engines. Gigabit Ethernet and Wi-Fi 6 with MU-MIMO maintain network throughput during long sessions.

Installation notes and common pitfalls

The tower measures 12.76 inches high, 6.06 inches wide and 11.53 inches deep, weighing 12.02 lb, so verify desk or floor space before unboxing. Front I/O includes two USB 2.0 ports, one USB 3.2 Gen 1 Type-C port, one USB 3.2 Gen 1 Type-A port, a global headset jack and a media card reader. Rear I/O adds two USB 3.2 Type-A ports, two USB 2.0 Type-A ports, DisplayPort 1.4, HDMI 2.1, DVI and RJ-45. The LGA 1851 socket limits future CPU upgrades to compatible Intel Core Ultra processors.
