is my PSU strong enough to handle these components overclocked?

[beasty6]

hey guys,

so ive recently upgraded my graphics card from a GTX480 to a HD 6990, now i know this card is another power hungry card and i really want to push the switch to overclock the card BUT.. my i5 760 is already at 3.6ghz and i have two HDD's four fans etc but my psu is a antec 750w true power psu, will it be enough or should i upgrade it?

im not sure my PSU will take it nd dont want to damage it, im also looking to putting my system under water and overclocking the CPU and GPU quite extremly.

would you guys reccommend an upgrade to this PSU?

I think you should be ok with the one you have unless you got a ton of hard drives running then you should consider upgradeing but with what you have you should be fine

750W will be easily enough.
