No, actually im getting it from a site who is building my pc, and then you are going to say "Build it your self, that much cheaper" but i can get the added tax of, so its like 400 euro's cheaper and you only can select the 600watt 700watt or 1000 watt, all from Cooler Master, i'll go with the 1000watt one and change my motherboard to a MSI H77MA-G43 wich is 40 euro's cheaper.
Well, that one is a bit overkill, but if you really don't have any models with those names with less watts, then go for it, but i advise not to go for a h77 board if you want to oc the i7-3770k, go with a z77 board you'll need it.
Or switch the cpu for a i5-3570k(if available) if the purpose of your build is mostly gaming.
You could go with a 670 or 7970 not much of a hit for performance and best price performance ratio.
But if you want to oc the cpu you'll need a z77 board, the h77 wont oc at all, just the turbo boost that it says.
Above all, if you can switch the cpu for a i5-3570k more the z77 board it will be the best choice, perhaps it will fit the budget with the 680 gtx.
You forget that the 700w psu is a lite one, and with a 680 gtx and i7 more stuff i doubt a 450w psu will do, a 550w good brand might or a 600w.
But the thing is it is the coolermaster lite model which is really bad.
