The 12V rail is the most important part of a moderm power supply. Both the CPU and graphics cards, the two most important and power hungry components in any computer, are powered by the 12V line. Voltage fluctuations can cause anything from high pitch noises, to lower CPU and VGA overclocks, system instability or even damage components.

Thanks to an elaborate design with microscopic tolerances and a detailed channel design, the bearing core inner case are constanly separated by a thin film of oil, and the two metal parts never actually touch! The channels on the bearing core act as a pump, constanly looping it back to the center, giving it no chance to leak. This results in extremely queit operation and an extremely long life.
