Tower Desktop with Core Ultra 7

The Dell ECT1250 is a tower desktop built around an Intel Core Ultra 7 265K processor with 20 cores and a 3.9 GHz base clock. It ships with 16 GB of DDR5 5600 MHz memory and a 4 TB NVMe solid-state drive. An NVIDIA GeForce RTX 3050 graphics card with 6 GB of GDDR6 memory handles display output. The system includes a wired keyboard and mouse and comes with Windows 11 Home pre-installed.

Thermals and Power in Daily Use

The 12.02 lb chassis measures 12.76 in high, 6.06 in wide and 11.53 in deep, providing internal airflow for the 20-core processor and discrete graphics card. A 30 MB L3 cache and Intel AI Boost NPU help manage workloads efficiently. Gigabit Ethernet, Wi-Fi 6 and Bluetooth 5.4 handle connectivity without adding significant thermal load during typical business, education or everyday tasks.

Build Integration and Expandability

Front ports include 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 a DisplayPort 1.4, an HDMI 2.1 port, two USB 3.2 Type-A ports, two USB 2.0 Type-A ports and an RJ45 jack. A Kensington lock slot and padlock loop provide physical security. Buyers who need more internal drive bays or a larger power supply for additional high-wattage cards should verify chassis limits before purchase.

Questions about this item

How do I install the Dell KB216 keyboard and MS116 mouse, and which front port do people plug the keyboard into by mistake?

Plug the KB216 keyboard and MS116 mouse into the rear USB 2.0 Type-A ports; the front USB-C port is data-only and will not wake the system from sleep.

Which component will need replacement first if the 4TB NVMe SSD fills up?

The single M.2 PCIe NVMe slot holds the 4TB drive, so adding capacity means swapping that drive for a larger one.

What thermal limit appears first when the Core Ultra 7 265K sustains 5.50 GHz turbo?

The 12.02 lb tower relies on its stock air cooler; sustained 5.50 GHz boost will hit the CPU temperature ceiling before the 3050 6GB GDDR6 card reaches its limit.
