PSU

I would prefer an answer rather than a link.
Also should i take the i7 950 over 930 or just stick with 950 (if i want a 4.0GHz overclock)
 
if its a single GTX 480 then nowhere even near 850W, have to be something seriously wrong for such a system to draw that much power. hell some people call 4870X2s power hungry but this one is running fine on 450W PSU (not the one in sig.) without and hiccups. :) would be fine with good quality 650W PSU i would imagine. (unless GTX 480s draw stupid amounts of power?)

and his link tells you everything you needed to know, even the power draw of GTX 480 SLI under full load?
 
well in the link posted the SLI GTX 480 rig with overclocked i7 didn't even draw 600W, so 850W could be considered overkill. ;)
 
595W for the whole system under load, thats not too bad. 650W, 750W, 850W, they'd all do the trick i would imagine, just depends how much 'headroom' you want, i doubt the cards will draw that power all the time playing games, etc. thats probably done with a synthetic benchmark to stress the cards to their maximum.
 
Ok so im going to go with the AX850 thanks for the help on that, now for the i7 should i go with i7 930 or i7 950, i would like to hit 4.0GHz
 
Yea but they also said:

"For anyone running a 2-Way SLI GTX 480 setup, we would suggest no less than a 800 watt power supply of good quality and surely we suggest a 1000 watt if you are overclocking anything in your system. (1000 watt PSU doesn't sound stupid anymore does it?!? wink ) For a person wanting to run a single GTX 480, we would suggest no less than a 600 watt power supply but we would be more comfortable with a 700 watt power supply; again if you are overclocking anything in your system. That should give you a safe bit of headroom and keep your PSU from running "in the red" continuously. It is hard to suggest any less for the GTX 470 either. NVIDIA's official stance is a 600w PSU for GTX 480 and 550w PSU for GTX 470.

We did see this, and it very much worth mentioning. With a nicely overclocked Core i7 920 processor (3.6GHz) and GTX 480 SLI, we saw at the wall wattages exceed 900 watts at the wall in some very stressful GPU system situation."
 
900W, are you serious? thats absolutely insane, planets don't even use 900W of power for goodness sake! what are NVIDIA doing to use so much power? :eek:
