DELL 01DW3 Pro Slim Plus QBS1250 Desktop PC Intel Core Ultra 7 265 32GB DDR5 512GB NVMe

Slim business desktop for office workloads

The Dell Pro Slim Plus QBS1250 is a compact desktop PC built around an Intel Core Ultra 7 265 processor with 32GB of DDR5 memory. It ships with Windows 11 Pro and a 512GB NVMe solid-state drive. The slim chassis includes an internal DVD-RAM writer and a wired Gigabit Ethernet port. This configuration targets business and mainstream users who need a space-saving system for daily productivity tasks.

Sustained performance within a 260W power envelope

The 260-watt power supply defines the thermal ceiling for the CPU, which runs at a 2.40GHz base frequency and can reach 5.30GHz turbo for short bursts. Under continuous multi-threaded load the processor will settle at lower clocks to stay inside that budget, so long render or compile jobs run slower than on a higher-wattage tower. Intel Graphics shares system memory and is suited to multi-monitor office work rather than heavy 3D or compute workloads.

Check expansion limits

The slim form factor restricts internal upgrades; there is no room for a discrete graphics card or additional 3.5-inch drives. Only M.2 storage can be added, and the single 260W unit may not support power-hungry peripherals. Wireless LAN is not included, so a USB adapter or wired connection is required. Buyers who need more storage bays, a second graphics output beyond the integrated ports, or built-in Wi-Fi should look at a larger chassis.
