It should be fine. It should pull less than 600W.

You should be fine. The wattage calculator usually tells you power you will use and the 700w on your PSU is max power. Normally a descent power supply will be "Certified" and tell you a percent like 80%. You take the max rated output 700w and multiply it by the percent 700 x .80 = 560. So a 700watt PSU rated at 80% is guaranteed to generate a continuous 560 watts. While you are close to this number, as long as you have a descent quality PSU you should be just fine.
