If a system with a decent gpu like radeon 6870 needs a psu abt 550W
and if some1 posses 650W or 750W is there any difference in terms of electricity bill??
I mean for 550W system a 650W is ok but if its abt 750W is there ne wastage in the additional watt???
(no thoughts of OC or CFX)

No, the psu is capable of supplying xxx watts, but if you only require a half of that, thats all it pulls from the wall
No 'wasted' power dude
