Small-form-factor business desktop

The Dell Pro Slim Plus QBS 1250 is a new small-form-factor desktop built around an Intel Core Ultra 5 235 14-core processor with a base clock of 3.40GHz and a maximum turbo of 5.00GHz. It ships with 16GB of DDR5 memory, a 512GB solid-state drive, Intel HD Graphics and Windows 11 Pro for immediate deployment in office environments.

Ideal for standard office workloads

This system suits organisations that need a compact, quiet PC for productivity applications, web-based tools and multi-monitor setups using the integrated graphics outputs. Buyers who require a discrete graphics card for 3D rendering, video editing or GPU-accelerated compute should consider a workstation-class tower instead.

260-watt power supply defines upgrade limits

The internal 260W power supply delivers enough headroom for the factory processor, memory and SSD but cannot support high-wattage add-in cards or large storage arrays, so expansion plans must stay within this power envelope.

Questions about this item

Will the 260 W power supply handle a future graphics card upgrade?

The 260 W unit is sized for the integrated Intel HD Graphics and the 14-core Core Ultra 5 235; adding a discrete GPU would likely exceed its capacity, so plan a PSU swap if you need more graphics power.

What thermal limit appears first when the 14-core processor runs at 5.00 GHz for long periods?

The small-form-factor chassis and 260 W power budget mean the CPU will hit its thermal ceiling before the memory or storage become bottlenecks, causing clock speeds to throttle under sustained all-core loads.

How loud is the cooling fan when the system sits at full load all day?

The compact Pro Slim case uses a single high-RPM fan that becomes clearly audible once the 14-core processor holds 5.00 GHz for extended sessions, so expect noticeable airflow noise in a quiet office.
