MINISFORUM X1-255 Mini PC Ryzen 7 255 - Compact HighPerformance

Our review of the MINISFORUM X1-255 Mini PC finds it best suited for users who need a compact desktop with serious multi-threaded performance and flexible connectivity. Powered by an AMD Ryzen 7 255 (8C/16T), the unit handles image editing, programming, light gaming and media playback without obvious bottlenecks. The combination of OCuLink for external GPU options, multiple video outputs and advanced networking makes this an attractive choice for power users who want a small footprint system that still expands to desktop-class tasks.

Key Features

• Processor: The Ryzen 7 255 delivers strong multi-core performance for productivity, photo editing and multitasking.
• OCuLink support: The onboard OCuLink port enables external PCIe4.0 x4 GPU enclosures for accelerated graphics beyond integrated Radeon capabilities.
• Multiple video outputs: One HDMI, one DisplayPort and two USB4 outputs allow up to four independent displays for multitasking or creative workflows.
• Networking: Built-in 2.5G Ethernet and WiFi 7 with BT5.4 provide fast wired and wireless connections for large file transfers and low-latency streaming.
• Cooling design: Large vents and an active cooler for memory and SSD help the system maintain sustained performance under load.
• Expandable storage and memory: Dual SO-DIMM slots up to 96GB and two M.2 2280 PCIe4.0 SSD slots offer plenty of room to grow storage and RAM.

Who It's For

The X1-255 is aimed at enthusiasts and professionals who want a small desktop that does not sacrifice performance: content creators on a budget, programmers who need lots of threads and home office users who want multiple screens and fast networking. Its OCuLink option also appeals to users who may add an external GPU later for heavier graphics work.

It is less well suited for users who demand a barebones plug-and-play gaming tower or those who prefer an all-in-one solution with an internal fullsize GPU. Casual users who only need a basic web and office machine might find the feature set larger than necessary.

Pros & Cons

Pros

• Compact size with a high core-count CPU for solid multitasking and responsiveness.
• OCuLink port offers higher-bandwidth external GPU support compared with typical USB4 options.
• Fast networking with 2.5G LAN and WiFi 7 plus multiple display outputs for productivity.
• Quiet operation and effective cooling keep thermals and noise levels low in most use.

Cons

• OCuLink is non-hot-swappable and requires use of one M.2 2280 PCIe4.0 SSD slot, which reduces internal expansion flexibility.
• Some customers reported mixed functionality experiences, so careful setup and compatible peripherals are advised.
