350 watt UPS and 850 watt Power Supply



So apparently I don't know much about electricity. I just got to thinking.. my UPS is like 350 watts and the power supply in my computer is 850 watts. Would that mean my computer will not stay on with the UPS in the event of power outtage?

*feels dumb*
I would think it would depend on the pc components, configuration and programs running. The typical gamer usually maxes somewhere around 300 watts during a gaming session. That is just a general statement. There are exceptions.

Don't forget the ups only lasts a few minutes - just enough time to save everything and shut down.
