AI Business Desktop for Enterprise

The Dell Pro Slim Plus QBS1250 is a mid-tower desktop built for enterprise workloads. It pairs a 15th Gen Intel Core Ultra 7-265 processor with 64GB DDR5 memory and a 4TB PCIe NVMe SSD. Integrated Intel Graphics handle display output across three DisplayPort connectors. Windows 11 Pro is pre-installed for immediate deployment.

260W Power Supply Thermals and Noise

A 260W power supply feeds the 20-core processor that reaches up to 5.3 GHz across eight performance cores. The mid-tower chassis provides internal airflow for the CPU and integrated graphics under sustained loads. Acoustic output remains low during typical office tasks such as document editing and video conferencing. The supply capacity matches the configured components without headroom for discrete GPU upgrades.

Bundled Peripherals and USB Hub

A wireless keyboard and mouse arrive paired for cable-free setup. The included Dockztorm portable USB hub adds data transfer up to 5Gbps through additional ports. Four USB 2.0, two USB 3.2 Type-C, and a headphone/microphone combo jack remain on the chassis front and rear. An internal DVD-R/W drive supports legacy media access for archival workflows.

Questions about this item

How is the 4TB PCIe NVMe SSD installed in the Dell Pro Slim Plus QBS1250, and what step is often missed?

The 4TB PCIe NVMe SSD mounts directly into the motherboard M.2 slot; the step often missed is removing the retaining screw before inserting the drive at an angle and securing it back down.

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

The 260W PSU has no user-serviceable parts; if it fails it must be replaced with an equivalent Dell unit, and dust should be cleared from the intake vents periodically.

What limit appears first when the Intel Core Ultra 7-265 runs sustained workloads?

The 260W power supply caps total system draw, so the CPU will throttle before its 5.3 GHz turbo can be held across all 20 cores under continuous load.
