Features:

 

Exactly as printed on the box.

 

  • High efficiency over 85% - Higher efficiency, lower energy loss, cooler our Earth.
  • Compliant with ATX12V V2.3 - Compliant with latest Intel ATX12V V2.3 PSU design guide.
  • 0.99 Active PFC rate - The highest utility rate and active switch for universal AC voltage.
  • Real and stable 400W/500W output - Continuous 400W/500W total DC output for real 100% loading.
  • DC quality with low ripple noise - Low ripple noise DC output for better devices performance.
  • Dual 12V output rail - Compliant with ATX12V requirement and support 240VA safety.
  • 140mm silent cooling fan - The bigger fan is equal to lower RPM and less noise.
  • Smart thermal fan control - Fan RPM was controlled by temperature and keep silence in typical loading.
  • All DC cables with mesh sleeve - Reduce airflow resistance for better thermal release in PC case.
  • PCIe graphic card connector support - Support high-end graphic card with PCIe 6/8 pin connector. (This one is incorrect, 6 pin only; 8(6+2) pin on 500W version).
