UPS efficiency is a very specific and significant. American HQ of IBM Corporation ever commissioned Allen a segall to do the efficiency and cost evaluation which shows in the following table:

Above table can prove that UPS's long-term cost is the lowest of all computer systems are not considered for the short period of time, are aimed at long-term work and purpose, I believe a wise choice is "the installation of an uninterruptible power supply" and the computer safe, you also peace of mind.
