Many people want or need a completely silent PC for their home or work. Unfortunately, as computers become faster, their power requirements and heat dissipation also grows higher. Both of these problems affect the power supply units, which have to provide more power while remaining quiet and cool. Cheap power supply units have to use powerful fans for cooling, which makes them rather loud for using in HTPC systems or other systems which need to be quiet. Thus many companies strive to design more powerful and efficient power supply units, which not only are able to provide great amounts of power but also to dissipate less heat and require less cooling..
