550w is about the minimum i recommend for any build now mate because the amperage of cards is going up some newer cards need as much as 42a on a single rail to work which is up significantly from dx10 card which needed around 32a. the 460 is still a relativity low power card so 550w will cover it with room to spare.
1 thing to remember that psu efficiency tends to start at 20% load so if you have a 750w psu you will need to be idling at around 120w before you make any power saving gains... below this there is no rating so you could be as low as 50% efficiency if your pc is idling. dropping down to 550w means you would only need to reach about 100w befor your efficiency climes to the correct ratings.
