I know that the antec 650w psu is powerful, but is it going to be powerful enough for all my hardare? here is a list of my hardware.
Mobo-evga 680 sli
cpu- intel quad core (plan on OC'ing to 3.2 ghz)
Graphics- dual nvidia 8800 gtx
hard drives-500g 7200rpm sata samsung
250g raptor
I also run 2 120mm fans and a freezone cpu cooler and freezone sli cooler.
Thanks for all the help.

Here is a calculator you can try:

I would suggest 850W or 1000W.

I have a similar system running 1000W and all is well but I wouldn't want less than 1000W.

Also be aware that eVGA has posted a new BIOS for that motherboard almost on a monthly basis ever since it was released.

The current is P30: 7/16/2007
