Next Generation High Quality Components and 4 Phase CPU Power Design
  Lower RDS(on) MOSFET Design (CPU Power Zone)
  
Traditional MOSFET Design (CPU Power Zone)
  
    A MOSFET is a switch that allows or disallows electric current to pass through an electronic circuit.
 
GIGABYTE was the first motherboard manufacturer to realize the importance of using only the highest quality components for the critically important CPU VRM zone of the motherboard , which is responsible for delivering stable power to the CPU. The GIGABYTE Ultra Durable™ 2 design (featured on GIGABYTE 2011 Select Motherboards) utilizes All Solid Capacitors manufactured in Japan which are rated to last for at least 50,000 hours in operational use. GIGABYTE Ultra Durable™ 2 motherboards also feature Ferrite Core Chokes with higher energy efficiency compared to more common iron core chokes and Lower RDS(on) MOSFETs which feature lower resistance, i.e. reduced power consumption and heat. Some motherboards in this segment feature the GIGABYTE Ultra Durable™ 2 Classic design, which features All Solid Japanese manufactured Capacitors and Lower RDS(on) MOSFETs.

GIGABYTE has further improved on the CPU VRM area by increasing the power phases from 3 to a 4 phase design. This allows for more stable power delivery to the CPU, as well as help smooth out power ripple and noise which is important for clean CPU power delivery.

Lower RDS(on) MOSFETs
• Optimized gate charge to minimize switching losses.
• Lower temperature, smaller size, better thermal characteristics.
What is a MOSFET?
A MOSFET is a switch that allows or disallows electric current to pass through an electronic circuit.

Standard MOSFET                                                         
  
 
      Lower Resistance = Lower Power Consumption = Lower Heat
  Power Consumption
 
Heat is a by-product
of power consumption
   
 
 
Power Equation: P = I2 x R
(P: Power, I : Current, R: Resistance)

Ferrite Core Chokes
• Reduced core energy loss • Lower EMI interference
• Resists rust better than standard iron core chokes
What is a Choke?
A choke is an inductor that stores energy and regulates current.
