    Take the side off and look at the label, its as easy as that. The 12volt amperage is also very important too.

    As i said, have a good look at the label, its wattage will be on there somewhere. If the 12volts rail is only 12 amps then its not a very powerful one.

    The sticker will look something like this

    What we need to know is what it says under +12V (there may be more than one of these, as shown in the picture) and under Peak Load or Maximum Output, either way it will be a number somewhere between 200 and 1000 with a W on the end ;)

    If you have any trouble, you can upload a picture of your sticker so that we can see it.

    It will have 3 numbers with a w after them. Look at Daveskaters picture. It says 580w. So that means it 580 watts. Your psu label will have something like it on it.
