Default Power Supply Pulling Power Const'ly?

If I have a 350w Power supply in my desktop computer does it const pull 350w All day or does it adjust through time, if it does Adjust what are the highs and lows?

I'm doing this to help calculate Power Cost, Thanks!

Default Re: Power Supply Pulling Power Const'ly?

it does adjust, how much depends on what you are doing with it

when you have your computer off...... it will draw like 1-2 watts from the outlet

when you have the computer on, idling (no programs running, and not doing anything) it will draw X amount of watts from the outlet

X is the minimum amount of power it needs to stay on
like a car consumes gas even when it's in park

when you are just web surfing, it'll draw a little more than X
like a car cruising on the highway

when you are doing intensive stuff, like play a video game, transcoding a video
it'll draw a lot more than X
like when you floor the gas pedal

for example,
idle: 185 watt
browsing: 200 watt
playing video game: 330 watt
