G.P.I --(Green Power Indicator)

The full name of G.P.I technology is Green Power Indicator technology, obviously technology utilized to low power consumption. G.P.I is a technology with remarkable power saving function: when you are using a computer with G.P.I mold turned on, you save averagely 10.5W in power consumption in the whole process than normal computer without G.P.I technology. The monthly cut in CO2 discharge amount produced during the electricity generating process can be as much as 1.6kg once you use the computer with G.P.I with an average of 8 hours a day!

That means about a cut of 19kg in CO2 discharge amount as well. Research has shown that a tree takes in 12kg CO2 each year, so using computer with G.P.I rather than ordinary computer a year can produce the same result as that of planting 1.6 trees on the planet. Since our life and work have been much dependent on computers and impossible to live without them, it is quite a choice to use computers with G.P.I technology instead to save money and do your bit silently to protect the environment in your life and work. Take Jetway's annual sales volume of 2 million boards for example, the contribution to our environment made by using these boards are equivalent to that made by planting more than 2 million trees!

Though with so many power-saving molds available, there is still demand for extra phases to cope with the high electrical current required when a CPU run at high frequency, so as to better disperse heat and enhance voltage transfer rate(most of the manufacturers use 3~5 phases and one-phase CPU NB power for current AMD AM2+ CPU ). We might as well take the 125W CPU HD985ZXAJ4BGH-the one with utmost power consumption- as an example to illustrate CPU power transformation. When this CPU works at its highest frequency of 2500MHz, its core voltage/current of is 1.300V/80.1A. However, when CPU runs at its lowest frequency of 1250MHz, the core voltage/current of CPU is 1.050V 39.4~8.06 A. We can see that the previous power consumption is almost 12300% of the latter, but the motherboards can not fully reach this goal in consumption differentia in reality, because of voltage transfer rate.

The common one-phase PWM can realize about 85% voltage transfer rate when loaded 5~20A, with optimal transfer rate when loaded at around13A and a drop in transfer rate after 20A. However, when running at current under 5A, PWM voltage transfer rate drops dramatically, even under 50%. Jetway utilizes G.P.I technology to enhance voltage transfer rate under low frequency and low electrical current circumstances. The green power indicator will automatically turn on when CPU workload is heavy and turn off when CPU workload is light to indicate power saving mold being activated.
The full coated inductance coil and OC-CON solid electrolysis aluminum capacitors help to realize optimal voltage transfer rate as well.
