So i bought all the parts for my new computer and here they are:

E6750
BFG 8800 GTX
Gigabyte GA-P35C-DS3R
CorsairTwinX XMS2 (2x1GB)
Antec P182
500 Gb Seagate Barracuda
1 DVD drive, 1 Floppy, 4 120mm fans
And Corsair 520W


I plan to overclock the CPU to hopefully 3.6Ghz(450x8) and the ram to 900Mhz to get a 1:1 ratio.

However now im panicing thinking the 520w aint gonna cut it? Ive read lots of reviews, forum posts etc etc stating its ok and others saying go for 620w.

With this setup and especially with the power hungry 8800gtx, am i going to be ok with the 520W?

That power supply can supply 40A on the 12V rails. That is definitely sufficient for your setup! It's a quality power supply which was a good choice, so you can count it.

Corsair has rated their power supplies so that they can run continously at 520W, this is different from some other makers in which they list the psu at the MAX power draw. So yes it will be just fine.

Try using this to figure what your system will need.

I ran it on your parts and it came up to about 450W. Of course that was with a bit of guessing as to the extact power you will need to get the CPU stable at that speed and some other minor things.
You should be fine since that is a good power supply and with 4 120mm fans then cooling shouldn't be much of an issue either.

Also that site typically has all the components running at a maximum something you will never be able to do, i would say your system typically won't use anymore than 350W even at maximum power draw.
