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 40% 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.
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).

80 PLUS Gold Certified and Lake C6/C7 States Ready
Toughpower GF A3 Gold series saves energy through its high energy efficiency up to 90% and is certified to 80 PLUS® Gold. It has been optimized to work with all generations of Intel’s processors to achieve maximum energy saving.
Toughpower GF A3 750W is certified to CYBENETICS PLATINUM in 115V and 230V input in terms of efficiency level. The overall efficiency rating is defined as ≥89% to <91% of 115V input and 230V input. There are six ETA certifications, covering an efficiency range from 82%. Besides the overall efficiency of a PSU, ETA also takes into account its overall Power Factor readings along with the efficiency of the 5VSB rail and the power that the unit consumes in standby (also called phantom power).
Toughpower GF A3 750W is certified to CYBENETICS A- in terms of the noise level. There are seven noise level certifications, covering from dead silent PSUs (<15db[A]) to quiet noisy ones(>40 db[A]). We use a solid methodology and states of the art equipment to measure the noise that a PSU outputs throughout its entire operation range, from almost zero noise output to full load.
