Ok I have a 250 watt PSU and I was wondering if it was enough to add an additional entry level video card. It does not say on the back of my computer how many volt/ amps it draws. I have a meter that can tell me though. The meter is fairly accurate from what I understand. If I measure a 75 watt lightbulb, it says I am drawing 75 watts. Anyway with only the tower plugged in and with the computer sitting at idle it said I was drawing 110VA and 75 watts. Does this sound about right for an entry level PC? I have a Dell Demention B110.

I am trying to figure out how much headroom I have with my PSU to add additional components. If it draws 110VA and 75 watts at idle what do you think it would draw at 100% CPU usage? I need to know if I have like 125 additional watts to work with or more or less or what.
