Dell Pro Slim Plus QBS1250 for business users

This small-form-factor desktop is built for office professionals who need reliable multitasking performance. The Intel Core Ultra 7 265 processor with 20 cores runs at 2.40GHz up to 5.30GHz and includes 30MB cache. It ships with 64GB DDR5 memory and a 512GB SSD under Windows 11 Pro.

Easy setup with verified configuration

The manufacturer box is opened for professional installation and testing before dispatch, so the system arrives ready to use. Integrated Intel HD Graphics handles multi-display output through DisplayPort connections. Connectivity includes 4 x USB 2.0, 4 x USB 3.2 and 2 x USB 3.2 Type-C ports alongside Gigabit Ethernet and Wifi-7.

260W power supply limits discrete graphics

The internal 260W unit powers the supplied components but leaves no headroom for a dedicated graphics card. Buyers who need GPU acceleration for rendering, CAD or multiple high-resolution displays should consider a larger chassis with a higher-wattage supply.
