Manufacturer's Features & Specifications
  • VRM (Voltage Regulation Module) Circuit offers high efficiency and Power density.
  • Compliance with the newest Intel standard ATX 12V V2.3
  • Compliance with the newest SSI standard EPS 12V V2.92
  • Ultra-silent operation with intelligent 120mm fan speed control
  • Eco-design for energy and money saving by Active PFC.(>0.9) / high efficiency(>88%)
  • Power Failure Detector will light up when OVP /OCP / OPP / SCP / UVP /OTP occur
  • Soft-start circuit A protection mechanism that limits the input inrush current by delaying the actual power-on of the PSU to prevent damage to it.
  • Green mode PFC control circuit by intelligent PWM power conversion
  • By using a single 12V switching circuit design you get a more efficient AC to DC conversion which leads to an overall more efficient PSU
