SFC
To reach the lower power consumption, Z68A-GD80’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 imped-
ance ensures low operating
temperature and stable power
supply when overclocking.
MSI Z68A-GD80 is equipped with three PCI-E x16 slots to support 3-Way
CrossFire as well as 2-Way SLI, allowing users to maximize their gaming expe-
rience with Nvidia and AMD graphics cards.
