SFC

To reach the lower power consumption, P67A-GD65 (B3)’s PWM adopt Green Choke design, SFC (Super Ferrite Choke), utilizing the latest material tech- nology - iron core. The material’s exclusive physical character allows SFC automatically to adjust the inductance value for optimal power efficiency based on the system’s loading. During light loading such as surfing the net or running 2D operations, SFC can help provide up to a 20% improvement in power efficiency compared to a normal ferrite choke. For heavier loading such as playing 3D games, SFC’s ultra-low impedance still helps to maintain a low operating temperature. Even when overclocking to the max, Super Fer- rite Choke offers an incredibly stable supply of power. Clearly, SFC can satisfy every possible power demand and usage scenario.

SFC provides over 20% power efficiency improvement during light loading. Ultra-low impedance ensures low operating temperature and stable power supply when overclocking.
