OK to use differant 360 power bricks with different systems?

Thanks Frankie,

Do you run the risk of frying your system if its not compatible, or will it just not work at all?

Edit:

Looks like the brick that came with the system is a 203w, and the one I was given is a 175W

I think the rule is if it fits it will work, which is why they put the spacers in the way that they did.
