Building a compact Mini-ITX PC can be an exciting challenge for enthusiasts and gamers alike. One of the key decisions in such a build is selecting the power supply unit (PSU). The Corsair RM850x is a popular choice due to its efficiency and reliability. But is it practical to use this PSU in a Mini-ITX build? Let’s explore the factors involved.
Understanding the Corsair RM850x
The Corsair RM850x is a high-quality 850-watt power supply known for its 80 Plus Gold efficiency rating. It features fully modular cables, quiet operation, and Corsair’s reputable build quality. These features make it a favorite among PC builders who prioritize performance and reliability.
Size and Compatibility Considerations
One of the main concerns when choosing a PSU for a Mini-ITX build is size. The RM850x measures approximately 150mm in length, which is larger than many compact PSUs designed specifically for small cases. This size can pose challenges in tight spaces where every millimeter counts.
Case Compatibility
Before selecting the RM850x, it is essential to check your case’s specifications. Many Mini-ITX cases support standard ATX power supplies, but some have restrictions on length. Cases like the NZXT H210i or Cooler Master Elite 130 may accommodate the RM850x, but smaller cases might not.
Power Requirements
The 850W capacity of the RM850x provides ample power for high-end components, overclocking, and future upgrades. For most Mini-ITX builds with mid-range components, a 650W or 750W PSU might be sufficient, making the 850W overkill in some cases. However, if you plan to add multiple GPUs or high-power peripherals, the extra capacity can be beneficial.
Practicality and Performance
Using the Corsair RM850x in a Mini-ITX build can be practical if your case supports the size and you need the power capacity. Its high efficiency and modular design contribute to cleaner builds and potentially lower energy costs. However, the size may limit your options for case choice and airflow.
Alternative Options
If size is a concern, consider SFX or SFX-L power supplies, which are specifically designed for small form factor builds. These units are typically shorter and easier to fit in compact cases. Brands like SilverStone and Corsair offer reliable options in these categories.
Conclusion
The Corsair RM850x can be a practical choice for a Mini-ITX build if your case supports its size and you require high wattage. Its efficiency, modularity, and reliability make it a solid investment. However, always verify case compatibility and consider your power needs before making a final decision.
