Dell Pro Micro QCM1250 MFF desktop

The Dell Pro Micro QCM1250 is a micro form factor desktop built around a 24-core Intel Core i9-14900K processor with 36MB L3 cache and turbo up to 6.00 GHz. It ships with 48GB of DDR5 5600 MHz memory and a 256GB PCIe NVMe M.2 solid state drive. Windows 11 Pro 64-bit is pre-installed, and a wired keyboard and mouse are included in the box.

Thermals noise and power in normal use

The compact chassis measures 182 mm high, 36 mm wide and 178 mm deep, weighing 1.40 kg. Integrated Intel UHD Graphics 770 handles everyday display output through DisplayPort 1.4a and HDMI 2.1 ports. Connectivity includes Intel Wi-Fi 6E AX211 with Bluetooth, gigabit Ethernet, and a mix of USB 3.2 Gen 2 Type-C, USB 3.2 Gen 1 and USB 2.0 ports for peripherals.

Behaviour under sustained load

The 14th Generation Core i9-14900K maintains high clock speeds across 24 cores during extended workloads, supported by the system's thermal design within the micro footprint. DDR5 5600 MHz memory bandwidth and the NVMe SSD keep data flowing for multi-threaded tasks. TPM security chip and Dell's 2-year warranty with free tech support back the platform for business and education deployments.

Questions about this item

How do I install the 256 GB NVMe M.2 drive in this Micro form-factor chassis?

The 256 GB NVMe M.2 SSD is already factory-installed; no internal drive installation is required. Simply connect power, attach peripherals via the front USB-C and rear DisplayPort 1.4a or HDMI 2.1 ports, then press the power button to start Windows 11 Pro.

What maintenance or replacement will the 48 GB DDR5 5600 MHz memory need later?

The 48 GB DDR5 5600 MHz memory is soldered to the motherboard and cannot be upgraded or replaced by the user. Maintenance is limited to keeping the chassis vents clear of dust using compressed air; no DIMM swaps are possible.

Which limit appears first when the Core i9-14900K runs sustained workloads in this 1.41 in wide MFF chassis?

The compact 1.41 in wide chassis restricts airflow, so the CPU thermal throttle limit is reached before power or memory bandwidth limits during prolonged heavy loads on the 24-core 3.20 GHz processor.
