   I calculted the power drawn by the above. The Computer itself draws worst case 150W. The NEC is
   rated at 105W. Now I understand W and VA aren't the same and the 150W, I tried to put a 85%
   efficiency factor in (switching supply.) My problem is this: When I have my monitor turned off
   for more than an hour, when I turn it on, it resets my system. Just turning the monitor on and
   off doesn't do this. Any Ideas?

If your monitor has had time to *cool down*, it momentarily draws a
*lot* of power while heating up.  This overloads your UPS.  I'm
afraid there is no good answer to this question; get a larger UPS
or "don't do that then."

Sorry not to have an easier answer...
