is 750w enough for my rig

[bistos12]

this is my rig :

CPU : i7 4820k
Mobo: ASUS x79 DELUXE
GPU : Gigabyte GeForce GTX 780 Ghz Edition
CPU Cooler : CoolerMaster Eisberg 120L Prestige
RAM : 2 sticks of 8 gigs corsair vengeance
SSD : 180GB Corsair Force GS
a 1TB WD caviar blue and a Blue ray optical drive

i ordered a Corsair AX1200i Platinum for my power supply but in my region it takes like 4 to 6 weeks to get one like that. I went with the AX1200i mainly because i wanna get another gtx 780 and put them in sli. I also have another psu from my older PC , a 750 w corsair i was wandering if this one will do until my AX1200i arrives

yes it will be perfectly fine.
you should not consume more than 605 watt at peak at the very max.
with a other 780 your power consumption will be 803 watt.
it might reach peak 830 watt.whatever psu above 900 watt will be fine.
