Compact slim desktop for office work

The Dell Pro Slim Plus QBS1250 is a small-form-factor PC built around an Intel Core Ultra 5 235 processor with a 3.40 GHz base frequency and a 5 GHz turbo frequency. It ships with 16GB of DDR5 memory and a 256GB SSD, running Windows 11 Pro out of the box. Integrated Intel Graphics handle display output, and a DVD-Writer provides legacy media support.

Suits space-constrained desks.

This system fits buyers who need a quiet, compact machine for productivity, web browsing and line-of-business applications. The 260W power supply and slim chassis limit expansion, so users who require a discrete graphics card, multiple internal drives or high-wattage components should look at a larger tower platform instead.

Ready to deploy with generous USB connectivity

Ten USB ports — including one USB 3.2 Gen 2x2 Type-C, two USB 3.2 Gen 2, three USB 3.2 Gen 1 and four USB 2.0 — give plenty of peripheral headroom without a hub. Gigabit Ethernet provides wired networking, while the 128GB maximum memory ceiling allows future RAM upgrades. The 11.9 x 3.7 x 11.5 inch footprint frees desk space for monitors or docking stations.

Questions about this item

Does this PC have built-in Wi-Fi, or do I need to add a wireless card?

The desktop has no WLAN hardware; you will need a USB Wi-Fi adapter or an internal card if wireless networking is required.

Can I keep using my older USB 2.0 peripherals with the USB 3.2 Gen 2x2 Type-C port on the front?

Yes, the single USB 3.2 Gen 2x2 Type-C port is backward compatible with USB 2.0 devices through an appropriate cable or adapter.

How can I verify the Intel Core Ultra 5 235 is reaching its 5 GHz turbo frequency under load?

Open Task Manager’s Performance tab or a monitoring utility and watch the CPU frequency climb toward 5 GHz during a heavy single-threaded workload.
