All IR® Digital CPU Power Design
GIGABYTE Ultra Durable™ 5 Plus motherboards use industry-leading PowIRstage™ controllers from International Recifier®. These 100% digital controllers offer incredible precision in delivering power to the motherboard’s most power-hungry and energy-sensitive components, allowing enthusiasts to get the absolute maximum performance from their next generation Intel® Core™ processors.

Single Package Design
IR has leveraged it's world class packaging technology developed for the DirectFET®, improving the thermal capability and layout of the PowIRstage® significantly over that of other MCM packages.

Other MOSFET layout implementations use a multi-chip, side-by-side arrangement of the high and low side MOSFETs and driver IC, taking up significant board real estate and creating more electrical leakage.

Cooler temps. = Higher Overclocks
Overheat
  
Not enough power
for overclocking
     
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.

OC Cool
The GIGABYTE Z87X-OC Force Motherboard features an extreme heatsink design for the PWM area that allows users to employ both passive, active and water cooling setups. A hollow body heatsink fitted with a silent integrated fan ensures superb heat dissipation during extreme overclocking configurations.
 

GIGABYTE OPT Fan Support
Many of today's 3rd party water cooling systems require CPU fan power support for both the cooling fan and the water pump. GIGABYTE 8 Series motherboards feature OPT fan support, an additional CPU fan pin header that can be used to connect a water pump and configured for continuous full speed operation. The OPT Fan is also useful for high performance coolers employing two fans.
