1200Watts sounds pretty good to power all of that, but it's Antec that I'm just scratching my chin about. I haven't purchased any Antec PSUs so I can't review on them, so I'm gonna suggest a Corsair AX1200i 1200Watt power supply. Corsair is full of quality and reliability,but it's totally up to you to change or not.

you don't need a 1200 watt PSU:

http://us.hardware.info/reviews/4632/32/geforce-gtx-700...

that is total system power measured "from the wall" to take PSU efficiency into account (using a good 90%) for the 780 tri SLI:
729*.9= 656 watts.

now the 780 will use ~40 watts more each than 770s but we'll leave that in there to account for the watercooling and extra HDs and whatnot in your system.

a quality 850 watt PSU can handle that load with out a problem.

CORSAIR HX850 850W 80+SILVER MOD ₱7,350.00

or if you want a bit more cushion, (though you don't HAVE TO) this will work:
CORSAIR HX1050W 1050W 80+SILVER MODULAR ₱8,850.00

here is the thing with getting too big of a PSU:


with the low idle usage, PSU efficiency takes a big nose dive when under a 20% load; between 3%-7%. so if you only look at the max load - you'll be getting good efficiency but when idling - which is more often than gaming - you throw efficiency out the window. . . just saying.

The Problem is theres no Corsair AX1200i 1200Watt on the website im buying on because as i said im in the philippines and i cant order that because you know why you could just suggest a power supply from that website

so with all the stuff i bought even the 3 gtx 770's,the corsair HX1050W can power it all i mean power the whole thing?
