A 550W PSU would probably work for you, however there are a couple advantages to having a larger PSU. First of all, having a larger PSU allows you to potentially drop another card in later without any problems for SLi. Also, power supplies are typically more efficient around 50-60% load so having a 750 watt PSU is going to draw less power from the wall than a 550w will providing they are of similar build quality.

yes, explained perfectly. Just to add, since there is less load on the psu, it will last you longer.

That really depends on alot of factors but if it is a good quality PSU you should be OK. What make model PSU did you get?
