Understanding PSU (Power Supply Unit) With 80Plus Logo

As people close to computer technology, I often encountered that prices at PSU (Power supply unit) with 80+ label is always above the price of regular PSU, I began to be interested to find out anything about the 80+ logo, after the meet turns out it is, that's a certification label on the power efficiency of the power supply where the PSU with 80 plus belonging to more power-efficient than those who did not.

Why Must There Efficiency Power On PSU?
So here goes, PSU is an AC current converter machine into DC, during the process of converter current electric power, mostly electricity turns into heat. This will reduce the DC output that should be in supply to the computer components. Efficiency made in various ways so that electricity is not wasted into heat so that more energy efficient. Therefore made standard 80 to certify PSU with a minimum efficiency of 80%.

More Clearly About 80 Plus At PSU
80 Plus is a voluntary program to promote PSU with efficiency above 80%, the label issued by Ecos Consulting (environmental care organization) in 2004. There are several types of the 80 Plus logo issued.

The efficiency of computer power supply is the output power divided by input power, input power is converted into heat remaining. For example, power supply with 60% efficiency 600WATT has run at full load (AC 100%) it will attract the power of 1000 watts of electricity and because it would be a waste of 400 watts into heat. On the other hand, a 600-watt power supply with 80% efficiency at full load running will draw 750 W of electricity and therefore will throw only 150 watts of electricity into heat.

Recognize the difference PSU 80 Plus Original And Fake
There are cases where companies claim that they have been certified PSU 80 Plus even though they do not yet have 80+ certificate, and in some cases their PSU does not meet the requirements for a certificate of 80Plus. Usually companies resell their PSU with a new name and a new company name, supply the retail level will not be eligible for the 80Plus, https://plugloadsolutions.com/ site has a list of all equipment that is certified PSU, making it possible to confirm that the supply actually meet the requirements.

Reasons Why PSU with 80 Plus More Expensive
Various methods are used by manufacturers PSU so that the PSU buatanya meet the 80 Plus certification, ranging from material component, circuit components, the addition of a certain ICs, etc. Most of the most influential is the material components used. Even so you still benefit in terms of the electric bill, your electricity bill will be reduced because the power supply you have a high power efficiency.
