Hello,
I am trying to put together a computer with some extra parts I have. I was wondering, will it hurt any of my parts if I have a 1000W older power supply from an old Alienware, work with parts that probably wont even exceed over 300W. I just need an extra PC downstair for surfing web and etc.
 
It won't hurt anything. It will over time cost you a little money as the powersupply will likely waste a little more electricity. Like having a couple of lightbulbs on that you can never turn off (without also turning your PC off).
