By adopting digital pulse-width modulation (PWM), the ASRock motherboard can provide CPU Vcore voltage more efficiently & smoothly. Compared to analog PWM, digital PWM can optimize the CPU power solution & provide a proper & stable Vcore for the processor. Premium gold caps are luxury capacitors. These 100% Japan-made solid capacitors are sleek, high gloss caps with a premium gold coating representing long life & stable performance. The advanced 6 + 2 power phase features sturdy components & completely smooth power delivery to the CPU. It offers unmatched overclocking capability & enhanced performance with the lowest temperatures for PC gaming enthusiasts. The ASRock motherboards support the PCI-E 3.0! PCI Express 3.0 can maximize the bandwidth for the PCI Express 3.0 VGA cards, provide ultimate graphics performance. Greater air flow, faster heat dissipation! ASRock X-FAN allows the motherboard to breathe smoothly. It will be automatically activated only when the system rises to a certain temperature under heavy-loading. Normally, ASRock X-FAN will remain deactivated to give users the quietest computing experience.
