would waste only 23.94W of energy, a 43% reduction in power dissipation. There are 8,760 hours in a year. Assuming the power supply is being run the entire time, we can calculate the total energy consumed per year in kWh as (375W + 32.61W)*8760/1000 = 3570.7kWh. Similarly, for the 96% effi ciency supply, it would equate to 3421.8kWh.
The difference of 148.9kWh per year may not seem like much at fi rst, but remember, we are only comparing a single supply. Data centers and server farms have thousands of racks of equipment, each requiring multiple power supplies. The cost savings begin to add up very quickly and can easily reach hundreds of thousands of dollars.
Custom Power Supplies for Further Effi ciency
As computing centers become larger and applications become more demanding, high-effi ciency power supplies will be more important than ever. They will not only help with cost savings and reliability, but they will help make the systems possible by reducing the heat and space needed.
