Hey everyone. I've got a little question.

Say I have a 550W power supply, but my computer isn't using all 550 watts on there. Will the PSU still suck up 550 watts, or will it only take in what it needs?

I've heard multiple answers to this and I'm kinda curious. Thanks, guys! :)

The current drawn from each voltage source is only the current needed at any given time. Just because the PS is a 550w one doesn't mean it draws that full amount of power at all times. That would be highly inefficient.

You're welcome. Glad devices don't really consume full power when it's not needed. :)
