Is A CORSAIR ax1200I SUFFICIENT?

Hi all. I'm the newbie with a bunch if questions. Maybe you guys can give me some input.
I'm running:
Intel 3930k stock settings
RIVF mb
H100i push/pull setup
32 gb 1866 corsair Dominator Platinum series memory
LG blue ray player
WD 320gb 7200rpm HD
9 120 fans 4 are Corsair HP
Corsair ax1200i
Evga gtx 3 way sli 570

My monitor and cards shut down and the monitor goes in a sleep mode while im gaming. the rest of the pc stays running. You guys had some input on another post I did. There was no solution, so I replaced the MB with the same MB. Same problem happening. I called Evga and they explained that I needed at least a 1500 w psu to run what I have. Do you guys agree?

No I did not, what I can say is that the fan speeds went so low I couldn't hear them anymore, I would assume then that they did shut down fully. If hey fully shut down and no fan is spinning, what does that mean? What should I be looking for. All cards work and tested.

On the PSU calculator that I use, it says you need 923w (@85%) and 940w (@100%) So 1200W should be fine
Being a platinum the reviews I have seen put it at 89/90% efficiency (1050W if its total power is 1200w, if it is like the EVGA 1500 (uses 1650w at full load)
So maybe it is the PSU.

Try running with only 2 video cards in your Sli, if you get the same problem, then its not the PSU that is the cause. If the problem goes away with only 2 video cards, that would bring us down to either a PSU problem or an SLi problem.

It does not happen while running just 2 cards. But on this new build, bf3 has crashed a couple of times with just the 2 cards. I know that could be a number of things.

Are the cards oced? Maybe 1 card cant handle the overclock but that should not shut down the complete pc.

No not at all. Never have o'clock them. I'm really starting to feel its the power supply.

Maybe the PSU has a general fail inside. I had many months ago a normal AX1200 with 3x580 and a 2600k oced to 4.5ghz and it had no problems at all to handle that.

Some friends around who have another strong PSU that you can use to test?

I don't have anyone else around! I'm the only pc nut around here! Maybe I should call corsair?!

You say with 2 cards it doesnt happen. Maybe switch 1 of the 2 card which are working with your third card just to see if its the video card (Like testing ram, just with videocards now :D)

After that i would contact corsair and ask for their opinion. Cant hurt to do that.
