The alloy chokes effectively increase up to 90% saturation current & feature a highly magnetic & heat resistant design, making the motherboard more efficient, stable & reliable. ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably & ensure longer lifetime. Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently & smoothly, so that the stability & lifespan of the motherboard is greatly enhanced.
