Business desktop for multitasking

The Dell Pro Slim Plus QBS 1250 is a small-form-factor desktop built for office workloads. It ships with an Intel Core Ultra 7 265 20-core processor running at 2.40GHz up to 5.30GHz, 64GB DDR5 memory and a 512GB SSD. Windows 11 Pro is pre-installed.

Upgrade from slower storage or less memory

Replacing a system that relies on a hard drive or offers under 64GB RAM removes bottlenecks in boot time and multitasking capacity. The jump is worth it when daily work involves several large applications or virtual machines running together.

Check display outputs and expansion needs

Verify that your monitors match the available DisplayPort connections for multi-display support. Confirm the 260W power supply covers any planned add-in cards and that the compact chassis fits your workspace.

Questions about this item

How much room does the small-form-factor Dell Pro Slim Plus QBS 1250 need on a desk or shelf?

The Small Form Factor chassis fits tight spaces; allow a few centimetres at the rear for the 260 W power supply exhaust and the Gigabit Ethernet, DisplayPort and USB 3.2 Type-C cables.

Which screw or latch must be released first when adding the 64 GB DDR5 memory or the 512 GB SSD?

Slide the side cover off after loosening the single captive thumb-screw at the back; the DDR5 slots and M.2 socket are then exposed — insert modules at 30° until they click.

What component will likely need replacement first in the Dell Pro Slim Plus QBS 1250?

The 260 W internal power supply is the only moving-part assembly; plan to swap it after several years of continuous business use.
