Dell Pro Slim Plus QBS 1250

The Dell Pro Slim Plus QBS 1250 is a small-form-factor business desktop built around an Intel Core Ultra 5 235 14-core processor running at 3.40 GHz up to 5.00 GHz. It ships with 16 GB of DDR5 memory, a 2 TB solid-state drive and Windows 11 Pro for professional environments.

Installation and common issues

The chassis is a compact small-form-factor design that fits standard business desks and racks. A 260 W internal power supply limits graphics upgrades, so adding a discrete card often exceeds the power budget. The manufacturer box is opened for professional installation and testing before dispatch.

Who this suits and who should look elsewhere

This system suits office workers, traders and multi-display users who need quiet, reliable performance for productivity applications and multiple monitors via Intel HD Graphics. Buyers who want more storage or a dedicated graphics card for rendering or gaming should look at larger workstations with higher-wattage power supplies.

Questions about this item

How can I verify the 14-core Intel Core Ultra 5 235 is running at its 5.00 GHz boost after setup?

Open Windows Task Manager, select the Performance tab, choose CPU and watch the live frequency while a heavy workload runs; the graph should show speeds approaching 5.00 GHz on active cores.

Which cables or accessories are not included with the QBS 1250 and must be purchased separately?

A display cable for the DisplayPort outputs and any USB-C peripherals are not supplied; the box contains the desktop, power cord, keyboard, mouse and Windows 11 Pro licence only.

Should I choose the 16 GB DDR5 configuration or look for a larger memory option for the QBS 1250?

The 16 GB DDR5 fitted is soldered and not user-upgradeable, so select this capacity only if your workload fits comfortably within 16 GB; otherwise a different model with more memory is required.
