There are power calculators on the web you can use if you want a number but maybe something easier to try straight away would be to add one (or two!) 1080s to your current build and see if the configurator throws up a warning. It will usually tell you if your PSU is way to powerful or whether it isn't powerful enough when you click 'continue'. If you change your build and it says nothing that's usually a good indication you have (at the very least) 10% contingency left in your power requirements.
