PSU for hd6950 xfire

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.

    The Cougar should do it! Total system consumption running Furmark 2 x HD6950 509watts http://www.anandtech.com/show/4061/amds-radeon-hd-6970-radeon-hd-6950/24
  3. yes, your current hec 700w will be plenty
  4. 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...
  5. CM700 good specs for a 700watt, 684watts available for the +12 volts http://www.cougar-world.com/cougar_cm.html#Specification

    mines a bit different http://www.pcgameshardware.com/aid,682780/Cougar-CM-Power-700-Review-New-PSU-series-tested/Reviews/

    only +12v1, +12v2 rails, 30amps each, still up for the job i guess?

    COUGAR 700CM dunno havent seen a review of it propably wont its not certified but that one got enough juice for his setup

    Dont confuse it with the 700CMX series which got certification -->CGR B2-700

    Good score here http://www.hardwareoverclock.com/Cougar_CM_Power_700_Watt-5.htm and here http://www.ocaholic.ch/xoops/html/modules/smartsection/item.php?itemid=340&page=7
