MINISFORUM Mini PC UN1250 Core i5-1250P - Compact 4K Workstation

In this review the MINISFORUM UN1250 Mini PC is evaluated as a compact desktop for users who need multi-monitor productivity and a fast, upgradeable small form factor. The clear reason to consider it is its balance of a 12-core Intel Core i5-1250P mobile processor with integrated Intel Iris Xe graphics, plus flexible storage and memory expansion, which makes it well suited to office work, light content creation and media tasks without taking up a full desktop footprint.

Key Features

• Intel Core i5-1250P processor: Delivers 12 cores and 16 threads for smooth multitasking and responsive application performance.
• Integrated Iris Xe graphics: Handles 4K video playback and light GPU tasks so streaming and casual gaming are fluid.
• Expandable memory and storage: Ships with 16GB DDR4 and a 512GB PCIe 4.0 SSD, with support for up to 64GB RAM and a 2TB M.2 drive for future upgrades.
• Triple 4K display output: HDMI, DisplayPort and USB-C support simultaneous 4K@60Hz monitors to expand a productive desktop workspace.
• Flexible connectivity: Includes 2.5G LAN, WiFi6E, USB-C, multiple USB 3.2 and USB 2.0 ports and an audio jack for a modern workstation setup.
• Small footprint: Weighing about 570g and measuring roughly 5 in x 5 in x 2 in, it fits tight desks and media centers easily.

Who It's For

The UN1250 is a good pick for professionals who need a space-saving desktop for office suites, web development, spreadsheet work and multitasking across several 4K displays; its fast PCIe 4.0 SSD and multicore CPU make it noticeably snappier than many entry mini PCs. Creative users doing light photo editing, video review, or streaming will also appreciate the integrated Iris Xe graphics and the option to expand RAM.

Users who need workstation-class GPU acceleration, heavy 3D rendering, or the absolute quietest fanless system should look elsewhere, since this unit targets balanced performance in a compact, actively cooled package rather than dedicated high-end graphics or fully fanless silence.
