The worldwide growth in computer server farms and Internet traffic has resulted in this infrastructure consuming global energy production at an accelerating rate. It is now estimated that the world’s 500,000 data centers and 32 million individual servers consume 1.5% of global electricity—about 300 TWh of electricity per year. The computer power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. Vitelic’s Trench Mosfet, Planar Mosfet and Superjunction Mosfet can be used for computer power supply in various power range.  They enable the high-end power supply system  to exceed 90% efficiency at optimal load levels.
