I am using this SMPS with that configuration for 1.5 months.....I have power hungry 9800GTX+ graphic card....though never faced any problem.....
But other guys says I need too change my SMPS if I want to use this SMPS with HD6850 graphic card.....
Personally....at the time of buying that SMPS I never thought that I will use it for more then one year...thats why I bought it...otherwise I would have gone with Corsair one....
I think right now you are not looking to upgrade your pc in near future....but may be later you will need graphic card to play some games...and that ime Cooler Master eXtreme Power 600 SMPS wont let you upgrade....
as SKud said Thumb rule.....you should buy hardware more powerful then you require right now.....for future proof....
One more then buy online instead of local dealer....in most of case it will be costlier then online....
and you wont have to hear those **** kind of excuses from local shopkeeper.....( I am really tired of it )
even I am buying my pendrive online....
