Nvidia spec is 600 watts for the 780, I've had one hooked up to my kill-a-watt meter and at 100% it pulled 480 watts. Testing different systems for power consumption with the kill-a-watt has shown me that the high end boxes very seldom pull over 700 watts total in game play. In a bench test with all air and h2o cooling at max, cpu and gpu at max, I see just over 800 watts from a 9590 with a pair of 7950's, 2 loops and 10 fans. If you OC the cpu and gpu with voltage increases this number will go up.

If you do decide to replace your psu measure the replacement carefully, the high output psu can get fairly large and there is no standard on the length of the body.
Thanks for all the reply guys, i appreciate it all. I'm going to buy a 1200AX psu from corsair, and buy a new computer case, the alienware area-51 has to many proprietary parts, if i replace the psu i wouldn't be able to use the system fans lighting and ventilation. Ill make a another thread.

Sounds like a great move to me. Have fun, it will be a killer rig.

Motherboard: Asus p9x79 WS LGA 2011
CPU: intel i7 4930k
GPU: GTX 780 TI Sli
Ram: DDR3 12gb 2133mhz
Cooling: Corsair H80i (liquid cooling)
Not sure about the hard drive, I know I got 1.15Tb
Anyways I have a standard 1000w PSU from dell (alienware area 51) is this good enough or do I have to upgrade to 1200w? I'm planning to O'C aswell
Going back to your original post, 12GB is an odd amount to run on that CPU/Mobo combo. You should be running either 4GB,8GB,16GB, 32GB or 64GB.
12GB will not work well. Quad channel stuff is recommended for that CPU/Mobo so 12GB will not work well.

You'll love the ax1000i, it's a beast and it's compatible with Corsair link software. If you add a Corsair AIO h2o cooler and Corsair case that would come together nice and display well in Corsair link.

Corsairs full tower cases are outrageously expensive tho
