Is a Seasonic G650 80 plus PSU ok for 980ti?

I'm currently running an overclocked 780ti and just ordered a 980ti but I've just been told a 650w PSU isn't enough.

Most reviews recommend 500w and as far as I'm aware the seasonic G650 is a good psu.

Will I be ok?

You're good to go =)

I've seen 650Watts peak while gaming with 2x 980Ti's

@PredatorRules: thankyou for the reply, you've made me very happy.

More than enough
