PSU Problem?

I just built up a machine with a 750w power supply (corsair). At the moment, it has 9 fans, 1 ssd, 1dvd-rw, a i7 930 thats going to be OC'ed to ~4GHz, and 6 sticks of OC'd memory (12gb total).

At the moment I only have an OC'd GPU (Nvidia 285GTX) that I would like to switch over to 2-sli.

My question is, should I swap out my 750w power supply for a 1000w? I was looking at OCZ's psu's and was aiming more toward that.

I'm not sure whether or not im going to have power issues (or currently have power issues) because I only have 750w, and while I'm still in the 30-day return area, I was wondering if anyone though it would be a good idea to perform a swap?

Thanks.

Sure, if you have the $$. Use another ps with at least 30 amps on each 12v rail.

The 750 watt Corsair has a single 60 amp rail and will stay in spec while providing 900 watts:

If you are planning to add a second GTX285, you have plenty of power already.
