    The length of time this UPS can keep your computer running depends upon the power consumption of your computer.

    Even though this UPS is 1500 watt, its output is only 900 watts with Power Factor Correction which means it will deliver an actual 900 watts at the design voltage.

    Going by the specs, it is supposed to deliver 900 watts output.

    If your total load is 900 watts then it should keep your equipment running for 2 minutes.

    If your total load is 450 watts, then it should be able to keep your equipment running for 11 minutes

      Thank you for answering. I have another question, tho.

      Let's assume that I have a typical desktop (use typical values). If that advanced CPU cannot hold the whole system running for 30 mnts (I use it for gaming), what type of CPU can last for 30 mnts?

    It depends upon how much power is being pulled by the computer which depends upon the processor, the fans, the number of hard drives, the monitor you have ...

    Run your system off of the ups to see how long it takes to discharge.
