Pro Micro QCM1250 Tiny Desktop

The Dell Pro Micro QCM1250 is a tiny desktop PC built for commercial environments that need full Windows 11 Pro manageability in a 1.4-inch-wide chassis. It targets IT buyers deploying fleets where desk space and power draw are constrained.

90W Adapter and Wireless-AX

The included 90W AC adapter powers the complete system without a separate power brick, while integrated 802.11ax Wi-Fi and Bluetooth replace wired LAN and peripheral dongles in open-plan offices.

Intel Core i7-14700T Base Clock

The processor runs at a 1.30GHz base frequency with a 5GHz turbo, so sustained multi-thread workloads stay within the tiny thermal envelope while burst performance handles brief compile or database tasks.

Questions about this item

Does the 16 GB DDR5 soldered to the board or installed in a slot determine future upgrade options?

The 16 GB DDR5 is installed in a slot, so you can replace it with higher-capacity modules later.

Under sustained load does the 90 W AC adapter or the 5 GHz turbo ceiling limit performance first?

The 90 W adapter caps sustained power draw, so the CPU will throttle before reaching its 5 GHz turbo for long periods.

How loud does the tiny chassis fan get when the i7-14700T runs all day at 1.30 GHz base?

The small fan spins up noticeably under continuous load, producing audible airflow noise in a quiet room.
