The efficiency rating of a power supply determines how much energy is wasted or lost when it converts the wall outlet power to the internal power components. For example, a 75% efficiency power supply that generates 300W of internal power would draw roughly 400W of power from the wall. The important thing to note about a power supply is that the efficiency rate will vary depending upon the load amount on the circuits as well as the condition of the of the circuits. Many power supply manufacturers are beginning to label units as high efficiency or HE. This is really a marketing term that can vary between manufacturers and even models. One high efficiency model might reach 80% efficiency levels while another might reach 85% efficiency. In addition, that 85% efficiency unit may only reach that percentage when it is at a 50% power load. When the unit is at 25 or 75% power loads, it may only have a 70% or lower level of efficiency. Some manufacturers are now listing the power supply efficiency ratings. It should be noted that many of these still list the optimal efficiency level. Only a few will list the efficiency levels for various load levels on the power supply. Be sure to look for these numbers before buying any PC power supplies. |
