Is my 700watt PS enough?

[ybgfhsd]

I've recently upgraded from:
EVGA 790i
Intel E8400
ZALMAN CNPS9700
2xgtx260 sli
EVGA 8800GTS 512mb
2gb OCZ DDR 1600
250gb Seagate Barracuda
OCZ 700watt PS
2 SATA DVD Burners

to:
ASUS P6X58D
i7 930 - stock
ZALMAN CNPS9700
2xgtx260 sli
80gb Intel SSD
250gb Seagate Barracuda
OCZ 700watt PS
6gb Corsair Dominator DDR3 2000
2 SATA DVD Burners

Before I upgraded I didn't have any problems. Since i've upgraded my pc reboots during games (Dragon Age) and when I try to run the multi gpu benchmark in Kombustor as soon as I select start it reboots. Before the upgrade I could run the multi gpu benchmark fine. I can still run the single gpu test with no issues. I've tried swapping the gpus same thing happens. I've got 7 case fans, so i don't think heat is an issue. I'm wondering if I'm pushing my PS to close to the 700watt range. Any help would be appreciated.

Thanks
