650 will run 2 7970's

550 is way more then enough even a good 450 watt will run it no problem

Yes I realize that but was just saying that I never feel safe when it comes to power supplies, I always go that fair bit more than what I actually could survive with. tongue.gif

but just look at your system: it wont pull more than 300W under full load and you use a 750W PSU. Even if you would use a 450W PSU you would still use only 66% of the PSUs capacity. wich is plenty of headroom.

I'd rather invest money in a better PSU than in a bigger one.

My 550W Antec Basiq VP550P is running my GTX580 perfectly, and that is much more power hungry than your 7950 iirc
