Ultra Quiet Smart Zero Fan

Designed with our Smart Zero Fan, the fan will not spin until the load exceeds 30% of the power supply, minimizing the fan noise.

<30mV Low Ripple Noise Design

Top-end build quality with low ripple noise. All ripples are lower than 30mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer.

80 PLUS Gold Certified and Intel C6/C7 States Ready

Tough power GF3 series saves energy through its high energy efficiency up to 90% and is certified to 80 PLUS® Gold. The series has been optimized to work with all generations of Intel’s processors to achieve maximum energy saving.


Toughpower GF3 1200W is certified to CYBENETICS GOLD in 115V input and PLATINUM in 230V input in terms of efficiency level. The overall efficiency rating is defined as ≥87% to <89% of 115V input and ≥89% to <91% of 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 GF3 1200W is certified to CYBENETICS STANDARD 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.
