AI Business Desktop

The Dell Pro Slim Plus QBS1250 is a mid-tower desktop built around a 15th Gen Intel Core Ultra 7-265 processor with 20 cores and 30MB cache. It ships with 32GB of DDR5 memory and a 2TB PCIe NVMe SSD running Windows 11 Pro. The system targets office and AI-assisted workloads that benefit from integrated graphics and high core counts.

Thermals and Power

A 260W power supply feeds the CPU, integrated graphics, memory and storage in a compact 12 x 12.25 x 4 inch chassis weighing 9.6lb. The Ultra 7-265 operates at a 2.40GHz base clock with a 5.3GHz maximum turbo across eight performance cores. Integrated graphics share system memory, keeping total platform power within the supply rating during typical business tasks.

Included Accessories

A wireless keyboard and mouse provide cable-free input, while a DVD-R/W drive adds legacy media support. An authorised Dockztorm portable USB hub expands connectivity with a 5Gbps data rate for additional peripherals. Three DisplayPort outputs and two USB 3.2 Type-C ports enable multi-monitor setups and fast external storage without extra adapters.

Questions about this item

How do I install the 32GB DDR5 memory and what step is commonly missed?

The system ships with 32GB DDR5 DIMM already installed in the mid-tower chassis; the step often missed is verifying both side latches click fully to lock each module in place.

What maintenance or replacement will the 260W power supply need later?

The 260W PSU has no user-serviceable parts; plan to replace the entire unit if fan noise increases or voltages drift after several years of continuous operation.

What limit appears first on the Intel Ultra 7-265 under sustained load?

The 260W power supply caps total system draw, so the 20-core processor will hit its power limit before thermal throttling becomes the primary constraint.
