Getting the 680w PSU will be much better for future upgrades.

You will NOT pull more electricty from your wall with a bigger PSU. You will pull more energy from the wall depending of what parts uses energy.

A PSU of 820w does not uses those watts, it means thats the max wattage it can convert from the wall to energy usable for your parts. So if you have efficient parts, you will use little power. If you have high performance parts, those will need a bigger PSU that is able to handle a load...

I hope that my rough explanation can help, any futher info how a PSU works there´s a lot of threats with very good information.

Have a good day :p
