PSU and Heat

Well I sort of disagreed with a computer salesman today. Then while at the local surplus store picking up some spare parts, I asked him and he sided with the computer salesman.

I was under the impression that unless you were drawing the extra power from a PSU it wouldn't create extra heat. Now both of these guys are trying to tell me that a 500 watt PSU would run hotter than a 400 watt PSU even though I would be drawing the same amount of power from both.

I thought the amount of heat was directly related to the amount of power drawn?

You're right, they're wrong. And I wouldn't worry about it anyway in respect to the system, since a power supply exhaust more heat than it puts into the case.

If the 400 watt ps was operating at peak, verses the 500 watt one, then the 400 watt one would be generating more heat, until it fried...

Salesman lie, even when they are telling the truth.

PSUs will only take what they need. They dont do the peek all the time. The more it needs, the hotter they get. But really this is a relative concept the PSU design and draw onto it.

Hell my purepower 420 burns hotter than my truepower 550.
