I remember reading somewhere that if you put a psu into a system that require less...

e.g. A 400w into a system that only needs 300w

that you can damage certain components...is this at all true, or apart from putting one in thats too small does it not matter which you choose?

Sounds like someone's pulling your leg. If you're looking to purchase, just get a good brand name...if it seems to cheap....it is.

Welcome to the forums.
Components only draw what they need from the PSU. Get the highest rated PSU(quality-wise) you can afford.

Don't believe that, it is BS

I say it depends on the PSU quality. If it's a crappy yet monsterous 650watt PSU, the rails could be some 20%+ from what it should be. This would eventually damage your components since the 5v line would be at 6v, and the 12v at 13.2v.

If you get a good PSU, you shouldn't have to worry.
