View all power supplies. Certify your product. Select from the manufacturers below to view power supplies. As we already know, efficient power supplies generate less heat. Since the power supply fan doesn't have to spin as fast to keep temperatures low, it ends up producing less noise as well.

Since 80 Plus power supplies require higher quality components and more sophisticated manufacturing, they tend to have better build qualities than low efficiency power supplies. Having passed 80 Plus testing also indicates that the power supply was able to deliver its full rated wattage, which is another quality indicator. The answer will depend on your power usage pattern. The more power-hungry your computer is and the longer you leave it running, the higher your power supply efficiency should be.

For example, a watt family computer that is used for four hours daily will do just fine with a 80 Plus power supply While the 80 Plus program has been invaluable in promoting the awareness and importance of high efficiency power supplies, its testing procedure does leave something to be desired:.

Fortunately this last issue can be easily resolved - Before buying a 80 Plus power supply, make sure that it is listed on the official 80 Plus website.

I've seen people say that you take the Wattage rating of the PSU, and the efficiency is how much power the PSU can really output for your component.

This is wrong. Efficiency has nothing to do with this. Simple answer: Heat. Any electricity not converted from AC to DC is given off as heat. I'm one that lives by the moto "nothing is impossible", so I'm not going to say flat out no. However, I will say that it is highly highly unlikely, and none of use will probably see it in our lifetimes or our childrens lifetimes. If I have a w PSU, does that mean it will always draw w of power? The amount of power drawn is determined by the components of the computer and how much they require.

The amount of power drawn will only be equal to what is needed, and no more. So what do the different 80 Plus ratings mean? What is in it for me? Ah, good question! Last edited: Aug 25, Joined Apr 11, Messages 11, 2.
