Is my PSU Big enough?

[ExiledLife]

I currently have a corshair 750 watt psu. I am going to upgrade to vista 64 bit and add a second hdd and another graphics card and get a quad core cpu. I would be running 2 4870 512meg editions (I don't know if I'm going to overclock since my current one started to bug out) crossfire, 2 seagate barracuda 500 gb hdds, 2 dvd drvies, 8 gigs of this ocz ram http://www.newegg.com/Product/Product.aspx?Item=N82E16820227289 and a q9550 most likely overclocked and my mother board is a DFI LANPARTY DK X48-T2RS http://www.newegg.com/Product/Product.aspx?Item=N82E16813136047. I also have an Antec Twelvehundred case with lots of fans and a big 120mm cpu fan. I know some of those things don't matter much but all the fans could add up to something. I don't really know much ab out power consumption. Would I be ok with the current psu I have or should i get a 1000 watt?

You'll be fine.

Good, because I don't have the money for a new one. Also, about how many watts does that setup take up anyway?

Your good on supply, If you wanted to know what the power consumption was on that system, i'd grab a P3 Kill-a-watt or something - If you wanted to know what the wall socket power usage was.
