👎 Cons
- The 12V-2x6 connector is specifically for NVIDIA GeForce RTX 40 Series, limiting its specialized high-power output for other GPU brands or older generations.
- The Zero Fan Mode only engages when under 50% load, meaning the fan will operate and produce some noise during heavier system usage.
- While certified for high efficiency, achieving peak efficiency still depends on the system's overall power draw and component selection.
- Being a specific model, it may not include all the modular cable options desired by every builder for custom cable routing or aesthetics.
- The "White" aesthetic of the power supply, while appealing to some, might not seamlessly integrate into all PC build color schemes.
