Lightbulb PSU Questions and myths

I have a power supply that uses 600 watts of power. My pc uses about 400 watts of power. Does this mean every time I turn on my pc I use a full 600 watts or does it use only what the pc requiers? If so I am scard to look at my electric bill. Is having a 600watt psu batter than a 450 watt psu?

PSU will only put out as much power as needed by the comp, and yes, most of the time, a more powerful PSU is better.

You only use 400 of the 600's good to have that extra wattage, just in case. You're fine the way you are. =)
