760 SLI power usage

[jbrauckmuller]

I know this subject has been covered in other places before, but I have a few specific questions I didn't see an answer to. I just picked up a second EVGA GTX 760 for cheap and figure I will need to upgrade my PSU to handle both cards. If I try both cards with my current PSU, is there any chance of doing hardware damage to any of my components if there isn't enough power?

 

I have an OCZ ZT 550w in my system right now. I know that the recommended wattage is ~700 for these cards in SLI, I also looked at a projected wattage website and it recommended around a 550 watt supply. So if there is a chance I can get away with my current power supply until Black Friday sales I will fire it up.

 

If not, I can get an EVGA superNOVA G2 750 watt for $65. Is this worth the price or should I wait until a better deal pops up?

 

Thanks and sorry for any errors, first post.

That G2 is a fantastic deal. Do it.
