What is the easiest way to see how many watts my power supply has?

Can I see this by viewing something on my computer or Do I open up my PC and look and where on the power supply should I look?

All power supplies are different, so there's no general answer to your question. Most have some kind of label on them that should include their max power, though.

Thanks, I found a label that said Max Power 480 Watts. Is that the rating? – Lynda Nov 19 '11 at 7:10
Sure sounds like it. – Dolda2000 Nov 19 '11 at 7:13
Every PC power supply has at least +5V and +12V output, often -12V and newer ones +3.3V too. I suggest you to read Wikipedia article to understand what does this power number indicate. – Cougar Nov 19 '11 at 10:27
