Forgive me for my lack of basic PSU fundamentals but..

If my computer only needs 350w and i have a 480w power supply.. will it only use 350w and save energy? Would it be the same as having a 350w instead of a 480w?

I'm 90% sure it saves energy completely to act like a 350w.

It will just supply 350watts. It isn't gonna "dump" any extra wattage not being used. IMO, higher rated PSU's tend to run a little more efficient because they don't have to dump alot of heat because they are running a small load.

So a high wattage power supply running a low load will create a high amount of heat?

no, a high wattage supply is more efficient, thus creating less heat as waste, while supplying the same amout of energy required by the system...

Awesome responses. This is why I love these forums :)
Just bought a 480w power supply for my new p4 to leave room for OC and expansion. Thanks a lot guys.
