Small Form Factor Business Desktop

The Dell QCS1250 fits a 24-core Intel Core Ultra 9 285K processor, 32GB DDR5 memory and a 4TB NVMe SSD into a chassis only 95 mm wide. Windows 11 Pro, a wired keyboard and mouse are included, making it ready for office deployment without extra peripherals.

Sustained Load Behaviour

The 24-core CPU reaches 5.7 GHz turbo frequency while the integrated Intel UHD Graphics 770 drives up to two displays via HDMI 2.1 and DisplayPort 1.4a. A 13 TOPS NPU handles background AI workloads without taxing the main cores during long work sessions.

Upgrade Context

The system replaces older small-form-factor towers that maxed out at lower core counts and slower storage interfaces. Buyers who need discrete graphics expansion or more than two native video outputs should look elsewhere, as the platform relies on integrated graphics and the compact case limits add-in cards.

Questions about this item

How much heat does the 5.7 GHz Intel Core Ultra 9 285K generate during all-day workloads?

The 24-core processor runs up to 5.7 GHz inside the small-form-factor chassis; Dell does not publish a TDP or thermal-output figure for this model.

Does the included Dell KB216 keyboard and wired mouse need any extra driver or dongle to work?

Both connect through standard USB-A ports and are recognised by Windows 11 Pro without additional software.

Can the HDMI 2.1 and DisplayPort 1.4a outputs drive a 1080p monitor that only has VGA or DVI inputs?

The ports output digital signals only; a passive cable will not work, so an active HDMI-to-VGA or DisplayPort-to-DVI adapter is required.
