*OVP (Over Voltage Protection): OVP prevents the damaging impact of excessive output voltage by shutting down the power unit.
*UVP (Under Voltage Protection): UVP ensures a constant flow of power to keep your components at their max performance.
*OPP (Over Power Protection): OPP safeguards the power supply from any overload, preventing over exposure to extreme power conditions.
*OTP (Over Temperature Protection): OTP automatically shuts down the power supply if the system overheats. This helps protect the power supply duration from any possible damage.
*SCP (Short Circuit Protection): SCP prevents any “rush back” of voltage that may cause harm to the power supply and other components.


•    Compliance with the latest Intel standard ATX 12V V 2.31
•    Single +12V rail for the most demanding SLI configurations
•    High efficiency design that meets 80 Plus requirements (85% typical)
•    Ultra-silent operation with intelligent 120mm fan speed control
•    Multiple protection design (OVP / UVP / OPP / OTP / SCP)
•    High reliability (MTBF>100,000 hours)
•    Double Layer EMI Filter restrains noise and injury to end-user
•    Huge bulk capacitor for hold up time >17ms at full loading 
•    Integrating Active PFC with PWM combo controller not only make PFC higher than 0.99, but also raises efficiency
•    Efficient transformer for reducing 5Vsb power loss when the system is at turn-off and sleep modes
