Sharma, I agree with you. There is no way to be certain without that information. However, if I were a betting man, I would bet that he would be alright. What kind of a 550 Watt PSU doesn't have a 30 amp 12v rail?

I could be completely wrong, but I am under the impression that it would be hard to find a PSU like that.

that is not true, you only try adding up all the wattages it will be more than 550w
the reason is, that is the peak amps on that rail the actual amp rating will be approximatly equal to (total wattage-(amp on +3.3)-(amp on +5))/12
in your case it is (550- (3.3*22)-(5*32))/12=26.45 approximatly
