efficient power-Fortron and Cooler Master
by admin ·
Also manufacturers of PC power supplies jump along the ‘ green ‘train . Almost all of them deal with 80 – plus labels on their products . What does this logo exactly , and above all it delivers something ? We test two 80 Plus Gold Fortron power supplies from Cooler Master and their efficiency.
A food must not only stable work today and sufficiently powerful , he must also deal with energy as efficiently as possible . The difference between what a PC power needs and what is actually being pulled from the wall determines the performance of a PC power supply .
For example, if the PC needs 60 watts and 100 watts of power to avoid them , then the yield is 60 percent . The higher the yield , the more efficient and therefore greener power . A diet that the 80 Plus logo (www.80plus.org) bears guarantees a minimum return of 80 percent taxes , 20 , 50 and 100 percent. With 80 Plus Gold are the requirements for higher yield , respectively 88 , 92 and 88 percent.
Compare
We compare the consumption of two 80 Plus Gold and Fortron power supplies from Cooler Master with a 600 watt 80 Plus power supply , and a kilowatt power of a few more years old. The measurement results shown in the table. Gold supplies are both evenly matched , and indeed often consume slightly less than the other two .
The return that you get in practice depends on your PC configuration , usage patterns and the ability of the diet . Of course you a thousand- watt power supply , but energy – efficient that will not work . The best voice your food and PC to each other . A good tip : charge up your PC with a heavy benchmark as Cinebench and PCMark Vantage and measure the peak consumption of a meter .
Ideal power
Multiply that number by 1.5 and you have a good measure of the ideal power requirement . Even a serious gaming PC is not fast more than 500 watts required, so a 750 watt power supply requirements. For the majority of PC users is a 500 watt power supply is more than adequate.
Another concern which you have to make is that 80 Plus Gold supplies are pretty expensive . Only after a few years the premium offset by lower consumption. Especially in PCs or servers that continuously enabled , an 80 Plus Gold – feeding a sound upgrade expressions . Already have an 80 Plus power supply , then upgrade to Gold far less interesting.
