Business desktop for multitasking professionals

The Dell Pro Slim Plus QBS 1250 is a small-form-factor desktop built around an Intel Core Ultra 7 265 processor with 20 cores running from 2.40GHz up to 5.30GHz. It ships with 64GB of DDR5 memory and a 1TB SSD under Windows 11 Pro. The system targets office workers and home users who need responsive multitasking and quick application loading in a compact chassis.

Pro chassis with versatile port selection

The durable Pro chassis uses a 260W power supply and advanced cooling to sustain business workloads. Connectivity includes four USB 2.0 ports, four USB 3.2 ports and two USB 3.2 Type-C ports alongside Gigabit Ethernet, Wifi-7 and DisplayPort outputs for multi-display setups. No optical drive is fitted, keeping the front panel clean for daily peripheral access.

20-core processor decides fit for heavy workloads

The Intel Core Ultra 7 265 delivers 20 cores and 30MB of smart cache with turbo speeds to 5.30GHz, making it the specification that determines whether this desktop handles demanding productivity tasks. Buyers who need discrete graphics performance for rendering or GPU-accelerated compute should look elsewhere, as the platform relies on Intel HD Graphics only.

Questions about this item

Does the Intel Core Ultra 7 265 processor limit the DDR5 memory to a specific speed?

The 20-core CPU runs at 2.40 GHz base and 5.30 GHz boost with 30 MB cache; DDR5 operates at the processor's supported JEDEC rate, which the board handles automatically.

What clearance does the 260 W power supply need inside the small-form-factor chassis?

The PSU is an internal 260 W unit built for the slim QBS 1250 case; allow a few centimetres at the rear vent for airflow and do not block the side intake.

After seating the CPU, what BIOS step enables the 64 GB DDR5 to run at full speed?

Enter BIOS on first boot, confirm the memory training completes, then save and exit; the system will boot Windows 11 Pro with DDR5 at rated frequency.
