Pros & Cons
👍 Pros
- Features Cooler Master's first in-house designed PSU platform, engineered for high-end performance with reduced temperature requirements.
- Achieves an 80 PLUS Platinum certification, guaranteeing a minimum typical efficiency of 92% under normal operating conditions.
- Equipped with a quiet 135mm fan, utilizing a fluid dynamic bearing for low RPM operations and silent cooling.
- Incorporates a Smart Thermal Control Mode with a Hybrid Switch, keeping the fan inactive until 50% load for silent operation during normal use.
- The hardware-based hybrid switch offers manual control to turn off the silent fan mode, allowing users to prioritize cooling or silence.
👎 Cons
- The "in-house platform design" is a first for Cooler Master, which might mean a newer design with less long-term field testing data compared to established platforms.
- While 80 PLUS Platinum certified, achieving 92% efficiency is a minimum typical standard, and real-world efficiency can vary slightly based on load and environmental conditions.
- The fan remains inactive until 50% load, which while silent, means there's no active airflow through the unit until it reaches a moderate workload.
- Specific details on the type and number of connectors are not provided, which is crucial information for system builders.
- The ARGB lighting, while a visual feature, may not be relevant for users who prioritize function over aesthetics or who use cases without a clear view of the PSU.
