The power rating simply indicates how much current the adapter can supply without burning out. Using a higher-rated power supply is fine; if anything, it will lead to fewer adapter heat problems.
Just to add this, with some power adapters using one of the correct voltage but excess current CAN cause a problem. That is because the voltage isn't regulated and if you don't load it enough the voltage is actually quite a bit above the rated value. Depending on the load, this could do some damage. This DOESN'T apply with the these Apple power adapters as they are regulated.

Hi,
I asked this question yesterday, but as an addendum to a not-really- related topic, so it may have been overlooked.
I've just bought a Micro Accessories power adaptor for my pismo. It's this one, from OWC:
<http://eshop.macsales.com/Catalog_Item.cfm?ID=6431&Item=MICACADPTG3>
This is sold as a Powerbook G3 adaptor, and I was told that it is suitable for a pismo, but I noticed that it's rated at 65W, whereas the original Apple adaptor is 45W. I'm fairly sure this is not a problem, but before I barbecue my Powerbook, can anyone confirm that?
