GIGABYTE X99 series motherboards use an all digital CPU power design from International Rectifier which includes both 4th Generation digital PWM Controllers and industry-leading 3rd Generation PowIRstage controllers. 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 new Intel Core i7 Extreme Edition CPUs.
This new generation of IR digital power controllers and PowIRstage ICs feature Isense technology, which provide more precise current sensing accuracy. This helps evenly distribute the thermal loading between the PowerIRstage ICs, preventing the overheating of each individual PowerIRstage, resulting in longer lifespan and better reliability.
POSCAP (Polymerized Organic Semiconductor Capacitor) is a high grade product recently which has better ripple current and dissipation factor characteristic. The most commendable of POSCAP is that in all kinds of operating frequencies, this product can maintain low impedance characteristics. So, POSCAP is suitable for motherboards with high-frequency switching power supply.
GIGABYTE X99 series motherboards integrate the absolute best quality solid state capacitors that are rated to perform at maximum efficiency for extended periods, even in extreme performance configurations. This provides peace of mind for end users who want to push their system hard, yet demand absolute reliability and stability, with ultra-low ESR no matter how high the CPU loading.
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.
OC Ignition maintains power to the motherboard and connected components while the system is shut down. This means that system fans will continue to provide airflow in cold bug situations, while i-ram drive users will not lose installed data. OC Ignition also allows users to pre-test water cooling setups, and allows case mod demonstrations without having to turn on the PC.
GIGABYTE OC Button includes a range of easy to use buttons and switches featured exclusively on GIGABYTE OC motherboards. The design philosophy behind OC Button is simple; to help enthusiasts and overclockers not only get the most performance from their hardware, but also the absolute most enjoyable OC experience.
GIGABYTE X99 motherboards feature a unique PCI Express design that utilizes 100% of all 40 lanes from the CPU when in a 4-Way or 3-Way graphics configuration. Standard designs limit all 4 main PCIe lanes to x8 (64Gb/s) bandwidth, but thanks to the onboard external clock generator combined with the direct connection of one of the x16 lanes to the CPU (switchless design), GIGABYTE X99 motherboards can unlock the full bandwidth available and provide the best graphics bandwidth possible to the user.
