Power supply step up

[Dorkenstein]

I have a Silverstone Decathlon 750w modular psu that I've had since 2008 I think, maybe longer. I run an overclocked Q9550 with 8gb of ram and am going to put everything in an Antec 1200 case with all fans except the door fan. No video card yet.

Since I know that nobody yet knows the true power requirements for the new Nvidia cards, would swapping out my Silverstone for a Seasonic 850w be a decent move? Or is the extra 100w not going to make a difference? Also, I really like the features and build quality of the Seasonic. Any advice? I will probably end up going the 'wait and see' route, but I was curious as to what others here thought. Thank you.

750W is plenty.

Unless you're planning to SLI / Crossfire two (or three, or four) really power-hungry cards, 750w will be fine. And if you are, then 850w still wouldn't give you much headroom - you'd be looking at 1000-1200w+ for a really exotic setup.
