High Quality 100% Japanese Capacitors All capacitors are high quality Japanese capacitors, to produce the efficient performance and to ensure the longer reliability. 135mm Smart Fan Fan speed will be adjusted according to the system load. And the fan will stop when the system is idle or under low load (less than 20% load). The 2 ball bearing structure provides longer life time. 2 ball bearing is the most durable fan construction with a durability of over 50,000 hours. The life of the 2 ball bearing is more than 5 years. 80 Plus Gold Certified 80 Plus Gold certified ensures to deliver 90% efficiency at 50% load. The better power efficiency leads to less power waste, less heat and less fan noise. And with the support of Intel processors, it will save more energy and more money. Single +12V Rail Single +12V rail provides the best power output, stability and compatibility for the hardware. It provides the easiest way to install the power cable. And it is the best design for overclocking.
