Be Smart, Stay Quiet

Featuring a 120mm fluid bearing fan to deliver excellent airflow. Furthermore, the Smart Zero Fan will not spin until the load exceeds 30% of the power supply, minimizing undesired noise.

High Quality Japanese Main Electrolytic Capacitor

High quality Japanese main electrolytic capacitor greatly improves the power supplies durability and ensures the Toughpower GF A3 series is stability and reliability.

High Amperage Single +12V Rail & High-Class Technologies

Powerful single +12V rail can properly deliver the power you need for the best compatibility. The use of LLC and DC to DC circuit design provides very stable operation and enhanced voltage regulation.

Built-in Industrial Grade Protection

To protect the hardware, GF A3 is built with industry grade protections: OCP(Over Current Protection), OVP (Over Voltage Protection), UVP(Under Voltage Protection), OPP(Over Power Protection), SCP(Short Circuit Protection), OTP(Over Temperature Protection).
