BRAND NEW WITH FULL DELL WARRANTY!!!

Overview

MFJ1D Dell Pro Slim QCS1250 Core Ultra 5 Desktop PC is a compact business desktop built around the Intel Core Ultra 5 235 processor, 16GB of DDR5 memory, and a 256GB PCIe NVMe SSD. The 14-core processor delivers up to 5.0 GHz turbo performance and includes an Intel AI Boost NPU capable of up to 13 TOPS, providing a combination of conventional business-computing performance and dedicated AI acceleration. The system uses integrated Intel Graphics and runs Windows 11 Pro.

Designed for business environments where performance and physical efficiency both matter, the MFJ1D uses Dell's slim desktop chassis while retaining useful internal expansion. It provides Gigabit Ethernet, Wi-Fi 6E, Bluetooth, DisplayPort 1.4a, HDMI 2.1, multiple USB ports, and low-profile PCIe expansion slots. The compact 303.5 × 95 × 293 mm chassis is well suited to corporate workstations, administrative offices, education environments, and other deployments where a traditional tower would consume unnecessary desk space.
