"The Kingwin KWI-450WAS Aluminum power supply kept the voltages within tight tolerances after achieving its output voltage. During the testing the voltages only varied 1 to 2 tenths of a volt. Other power supplies that I have tested, the output voltages would vary between 5 and 9 tenths of a volt. This type of fluctuation over time would put undue stress on components causing premature failure and possibly the loss of data."
