HD6970 Crossfire in 650Watt?

[ryantan1121]

Hi,

I currently has 1 Sapphire HD6970 in my system and I has one Antec TP650 PSU.

I wonder if I want to crossfire two HD 6970 in one system, would the PSU has sufficient power to run them in full load?

Here is the review i got from website, it can be seen that the power consumption of HD6970CF will attract about 600 watt to run total system when testing Crysis 2.

I have run another test in this website: It says recommended is 650watt.

Is this mean that my PSU is good enough to run?

Do you have any experience in these two card?

If this is your PSU http://www.antec.com/Believe_it/product.php?id=MTc1OQ== I believe it could do it, although on the low end since it has 648watts available on the +12 volts.
