Fist one gives a "total power" of 660watt, second one gives a "peak power" of 650watt.

I'm no psu guru, but I would be inclined to think that both psu's are similar?

Smokey is correct, but if your using lots of internal power guzzlers (HDD, DVD drives/writers, etc) id go witht he 2nd one as it has a higher total power on the 12v rails which is what the majority of these use.

It looks like the first one has 3 12v rails? It looks like it has a total of 456W on the 12v combined. I know my enermax Whisper 420w has 2 12v rails... If that is indeed the case I would go with the first one.

So multiple rails with lower Aperage is better then one with bigger ?
