Thanks of the fast replies!
Great! So, should i stick with this one - or would you recommend finding a less powerfull one? I dont mind the price of this PSU.
So the main reasons for a downgrade would have to do with less heat and perhaps less noice.
Don't skimp on your PSU. It is the heart and muscle behind your system. 650 watts would be my minimum recommended, keeping in mind that you won't be able to SLI anything in the future (not that you would need to with a TITAN!).
