80 PLUS Bronze 230V EU Certified


80PLUS Bronze guarantees 85%, 88%, 85% efficiency

with 20%, 50% and 100% load rates,

significantly reducing overall system power consumption.  

The higher efficiency of the PSU means that

there is less leakage of current,

which means less heat, high frequency noises,

and fan noise.

Semi-modular PSU


Semi modular design minimizes resistance

and voltage drop on the cables and lowers

impedance to further enhance energy efficiency,

connecting only the cables your system needs to

allow for smooth airflow to cool the system.

① Active PFC With 99% Maximum Power Factor


Active PFC system with maximum power factor of 99%

providing consistent and stable output as well as

high energy efficiency.  

High efficiency ensures safe, stable system operation

with low component noise, less heat from parts,

and minimal fluctuation of power supply. 



② Built-In EMI Filter For Noise Reduction


EMI filter is installed to suppress frequency

that causes noise for better system operation.


③ 12V DC-TO-DC Convertor With 100% Availability
