👎 Cons

  • The 12V-2x6 connector is specifically for NVIDIA GeForce RTX 40 Series graphics cards, limiting its unique benefit for older or different GPU architectures.
  • While "ultra-low noise," the fan will still generate some sound when exceeding 50% load, which may be audible in very quiet environments.
  • The ATX 3.1 compliance is a benefit for modern systems, but older PC builds might not fully utilize its advanced features.
  • Specific dimensions of the power supply unit itself are not provided, which could be a factor for case compatibility.
  • The 1000-watt capacity might be excessive for budget or mid-range PC builds, potentially adding unnecessary cost.
