Yes. You can have a PSU of any wattage greater than what you need. You'll only run into a problem if you have a PSU with less wattage than what you need.

just make sure the power supply has one rail not a split rail system. with gaming rigs and split rails on the 12v line with some gpu they can pull more voltage then ether rail can output. also make sure your buying a good brand power supply.

It depends on the PSU you are using. A bad quality 550W PSU that is not efficient will be easily run over by a good quality 400W PSU. It is not how much power it draws from the socket but how much it actually delivers to your system that matters.

This build will draw less power than you say...it will draw around 250w.if you want to buy a psu,don't buy the first psu you see that says 550w...you have to look the amberes,if the company and the model is good...about your question,every psu will work for your system,from a quality 400w to a 1200w(example)
