hi guys, i'm planning on adding another hd6950 (unlocked shaders only), just want to ask if my hec cougar cm 700w will be enough for the crossfire setup, according here http://extreme.outervision.com/psucalculatorlite.jsp it will be but some review site states 750-800+watts is recommended

specs:

intel i5 650 @ 4.2ghz 1.35v
gigabyte ga p55a ud6
ocz 4gb ddr3 1333
sapphire hd6950 unlocked
60gb g.skill phoenix pro ssd
2tb seagate hd
liteon dvd writer
scythe yasya w/ 120mm fan
thermaltake v9 w/ 3x120mm and 1x140mm fan

i also plan on overclocking the cards for some games, thanks.

wrong. HEC has a few junk ones. COUGAR is a division of HEC. COUGARs are decent power supplies. a 700w COUGAR is plenty. by the way, he stated he has a cougar cm700 model psu...
