．A user using 980W high efficiency power supply would save $424.86 of electricity per system
(97W / 1000W x 43800hr x $0.1 = $424.86, assuming $0.1 per 1KWHour of electricity over the
period of five years.)
．Also the reduced heat would means less cooling is needed. Another 97W or more power for cooling
can be saved depending on the environment.
．Therefore for using 980W Super Micro power supply, the total saving can be $849.72 or more per
system for 5 years of operation! For a data center which uses 1000 systems, it can save $169,944
per year (including systems and cooling)  A computer consumes 700 Watt energy using a Super Micro 980W power supply with 90% efficiency
* Efficiency is output power divided by input power (778W x 90% = 700W). The power supply will
fetch 778W of electricity which user will be charged by the electric company.
* The 78W difference is the energy lost to conversion which will release heat to the surrounding and
increase the system temperature. Cooling will be needed to compensate that 78W heat
generated. 
If the same system switches to another top tier company power supply with 80% high efficiency
