Two-Forward Switching Circuit Design
Dual forward Converter Circuit designed for High efficiency & reliability
The energy efficient Green IC circuitry consumes much less standby power (less than 1W) compared to other PSU’s without this feature.
This product complies with ErP Lot 6, the Standby Power and
High Energy Efficiency standards of the European Union.
The latest PSU design standard is incorporated for compatibility with a wide range of CPUs, motherboards, and graphic cards.
Dual independent +12V outputs provide a stable power supply to major PC components.
ATX20+4 Pin Main Connector broadens the range of motherboard compatibility.
Two ATX12V CPU 2x2 (4-Pin) power cables can be combined to form an EPS12V CPU 8-Pin power cable.
Ultra quiet 120mm Sleeve Bearing fan increases airflow while minimizing noise for a superbly quiet computing environment.
Heavy-duty protection circuitry of OVP, UVP, OPP and SCP.
