Compact business desktop

The Dell Pro Slim Plus QBS 1250 is a small-form-factor desktop built for office productivity. It targets professionals who need a space-saving system with a modern processor and ample memory for daily multitasking. Windows 11 Pro is pre-installed for immediate deployment in managed environments.

260 W power supply and integrated graphics

A 260 W internal supply powers the 14-core Intel Core Ultra 5 235, which runs at a 3.40 GHz base clock and can reach 5.00 GHz. Integrated Intel HD Graphics handles standard business displays without a discrete card, keeping heat output and acoustic levels low for quiet office settings.

64 GB DDR5 memory capacity

The system ships with 64 GB of DDR5, a figure that determines whether the machine can handle large datasets, virtual machines or heavy multitasking without upgrades. Buyers who need more memory than this single configuration provides should consider alternative platforms.

Questions about this item

How do I install the 64GB DDR5 memory and what step is often missed?

The 64GB DDR5 modules slot into the motherboard DIMM sockets; the step people miss is pressing each stick down until both retention clips click fully into place.

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

The internal fan and electrolytic capacitors inside the 260W unit degrade over time; plan to replace the whole supply after several years of continuous business use.

Which limit appears first during sustained loads on the Intel Core Ultra 5 235?

The 260W power budget caps total system draw before the 14-core processor reaches its 5.00GHz turbo ceiling under prolonged heavy workloads.
