Cool Power, Inside and Out |
 |
GIGABYTE Ultra Durable™ 5 motherboards use IR3550 PowIRstage® ICs, which feature the industry's highest 60A rating, with Lower Losses, Higher Efficiency and Excellent Thermal Management.
|
|
 |
The layout and packaging use copper connections for all power paths rather than wire bonds, reducing losses due to high resistance wire bonds as well as high inductance which causes ringing and high AC losses.
|
Power connections between the MOSFETs use very low loss copper, reducing losses and helping to spread the heat. |
Specialized MOSFET driver IC by International Rectifier. |
High side MOSFET (Control FET) has very low gate charge. Low side MOSFET (SyncFET) has an integrated Schottky Diode for even higher efficiency. |
The current has very short paths from the bottom of the device, through either the control FET (duty cycle ON) or the Sync FET (Duty cycle OFF) and through the copper clip. This is another reason the device is so durable and can handle 60A. |
Custom Copper leadframe conducts heat away from the silicon. |

CPU Power Zone Q & A
|
| |
What is the CPU Power Zone ?
The CPU Power Zone contains the various components of a motherboard that are responsible for delivering power to the CPU (PWM controller, MOSFET Drivers, High and Low side MOSFETs , Chokes, Capacitors and related circuitry).
What is a MOSFET ?
A MOSFET is one of the most critical components of the CPU power zone, as it is a switch that first allows or disallows electric current to flow to the CPU. Its switching is controlled by the MOSFET driver and PWM controller. It is also one of the most expensive components of the power design.
What is a Power Stage ?
A Power Stage is a single chip that includes the MOSFET driver, 1 high side MOSFET and 2 (or sometimes 1) Low Side MOSFETs . Power Stages are made using a more advanced manufacturing process, and are therefore more efficient.
What is a Traditional MOSFET (Also known as D-Pak MOSFET...) ?
A Traditional MOSFET is a less advanced MOSFET design that is used in a traditional CPU power zone where the MOSFET drivers and High and Low Side MOSFETS are each individual chips (multi-chip MOSFET design). They are less expensive and less efficient than single chip Power Stages. |

High Efficiency = Low Power Loss = Less heat = Longer Lifespan |
| |
| |
IR's IR3550 PowIRstage® are more power efficient and operate cooler than competing MOSFETs, resulting in longer component lifespan and more head room for greater overclocking performance.

| |
| |
IR3550 PowIRstage® ICs remain cooler than other MOSFET designs, allowing users to overclock to greater levels of performance. Each power component has a maximum thermal operational temperature, and once it is reached, adding more voltage will only result in a failed overclock. Since IR3550 PowIRstages® are able to operate at cooler temperatures at higher voltages than traditional designs, overclockers are able to have more headroom to increase voltages, resulting in higher potential overclocks. |

2X Copper PCB |
GIGABYTE Ultra Durable™ 4 design features 2X the amount of copper of a traditional motherboard for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE's Ultra Durable™ 4 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2X Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking.

| New Glass Fabric PCB |
Glass Fabric PCB technology uses a new PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate compared to traditional motherboard PCBs. This offers much better protection from short circuit and system malfunction caused by humid and damp conditions. |
