Barebone mini PC for self-builders

The minisforum MF-UM880Pro(0+0)US is a barebone mini PC that arrives without memory or storage. It targets system integrators and enthusiasts who want to choose their own DDR5 SO-DIMM modules and PCIe 4.0 M.2 drives. The chassis measures 66.6 by 130 by 127 millimetres and weighs 707 grams.

Ryzen 7 8845HS with Radeon 780M graphics

The processor delivers 8 cores and 16 threads with a base clock of 3.8GHz and a boost up to 5.1GHz. Integrated AMD Radeon 780M graphics drive up to four displays through two USB4 ports, one HDMI 2.1 FRL port and one DisplayPort, supporting 8K resolution at 60Hz. Dual-channel DDR5 5600 memory is supported up to 96GB.

Suits DIY builders needing compact multi-display

This unit fits users who need a small footprint with dual 2.5Gbps Ethernet, Wi-Fi 6E and Bluetooth 5.2 for dense connectivity. It is not for buyers who want a ready-to-run system with Windows pre-installed, nor for those who require discrete graphics or more than two M.2 slots. The 120W power adapter accepts 65 to 100W USB Power Delivery input.
