Slim Desktop for Business

The Dell Pro Slim QCS1250 is a compact desktop PC built for professional environments. It runs Windows 11 Pro on an Intel Core Ultra 5 235 processor with vPro technology. The 14-core CPU reaches 3.40 GHz base and 5 GHz turbo frequencies. Integrated Intel graphics share the 16 GB DDR5 memory.

Upgrade from Older Office PCs

This system replaces ageing desktops that struggle with modern multitasking and security requirements. The jump is worth it when your current hardware lacks vPro manageability or DDR5 bandwidth. The 180 W power supply supports the slim chassis without external bricks. A DVD-Writer remains included for legacy media access.

512 GB NVMe 4.0 Storage and 16 GB RAM

The PCIe 4.0 M.2 SSD provides fast boot and application loading for typical office workloads. Capacity runs out quickly with large local datasets, media libraries or multiple virtual machines. The single 16 GB DDR5 module leaves one slot open for a future memory upgrade. Gigabit Ethernet handles standard network traffic.

Questions about this item

What clearance does the Slim PC chassis need for the 180 W power supply and DVD-Writer?

The Slim form factor fits in tight spaces; allow a few centimetres at the rear for the 180 W supply ventilation and at the front for the DVD-Writer tray to eject fully.

Which screw secures the M.2 512 GB PCIe NVMe 4.0 drive during installation?

The M.2 slot uses a single mounting screw — insert the drive at an angle, press down, and tighten that screw; skipping it lets the drive lift and lose contact.

When should the 16 GB DDR5 module be upgraded instead of adding a second stick?

The board has one slot populated with a 16 GB DDR5 module; if you need more than 16 GB you must replace it with a higher-capacity DDR5 stick because no second slot is free.
