my system is :-
intel core i5 2400k

^ Stress the "good quality". Not all power supplies of equal rated power are the same. Some exaggerate while other outright lie. Tell us where you shop and a budget and we'll pick you out a good one.

BTW if geofelt says something ... good idea to listen.
one quality psu is the way to go.

A decent 550w power supply should be more than enough. I'm running my 7850 off a 380w power supply right now. Make sure to try and get a power supply that is at least 80+ certified or better.
