Hello,

If I have a computer that requires a 600 watt psu but I use a much more powerful psu (e.g. a 1000 watt psu)
can this damage the computer in any way?

What happens to the extra 400 watts?

(This question is regarding all types of power supply units: ATX, ATX 12V, etc...)

No it will not hurt it. There are no extra wattage, there is only a total wattage of which your computer will use as needed.

Hi Megaman1

Not at all.
The problem occurs the other way round - if the computer had a higher power rating than the PSU could deliver then you would have a problem.

What happens to the extra 400 watts?

Nothing - the PSU will only supply the power that the system wants. If the system only requires 600W then that is what the PSU will supply.

Nothing will happen to your computer for having a power supply with more watts than needed. At least when you decide to add new hardware that will add to the wattage requirement then you won't have to go out and buy a bigger psu. It's always best to give yourself some wiggle room when it comes to psus. As for the other 400 watts: your computer will only pull down the watts needed. The additional doesn't really exist unless needed.
