would this enough power to run 3xvga?

I have 1x 750w corsair and 1x750w pcp&p psus.
The setup I will have:

1 gx2 + 1 9800gtx + 1 gts in evga 790i board
[email protected] + 2x raptor + 1 sata hdd

this machine will full load 24/7 (with folding )

I guess any psu above would do right ?

180w + 110W + 100w = ~400w for vga ?
165w for 3.4ghz quad
3hdd + dvdrom + fans = 60w

total is 625w ??

And also, would be ok if later i take out gts and replace with one more gx2 ?


thnx

NM I was looking at total system loads..
