Now: Yes, by about 30%.

 

When you get the second 780ti and OC: Not at all.

@Drossel

Yeah you could run it on 450-500W most people buy 600-650W power supplies for single GPU solutions to have head room

Consider whether you're actually going to end up buying a second 780Ti my advice would be to just upgrade to a new GPU 3-4 years from now

Yes, but if you do upgrade and OC the balls off of your stuff later on then it won't.

it provides you go overhead for SLI do the road.

 

If you want to save a few dollars, might I recommend the 860w 80plus platinum by Seasonic?

For a i7 and nvidia card it's fine but for a crossfire intel/amd build it could run tight.

For SLI 780Ti and an overclocked 4770K it's more than you'll get out of it but certainly not "overkill".

AX 1500i would be overkill but that PSU isn't.

I'd rather go overkill. At least you will know that you have the option to expand your system and install new components later, like a graphics card to sli or crossfire.

you did say you're getting a second 780 ti and oc them both.

 

pretty much that psu is not overkill.

 

besides the wattage I think everyone else is forgetting the "How long is the warranty" no matter what you do even if you just buy a 550w-660w psu from good brands if it only has a 1 year warranty it doesn't matter as after 1 year if something went wrong you're so fucked.

Live your life like a dream.

I wouldn't go with the ax860i if noise is a concern.

it's not total overkill but it's more then you need, even with both the cards overclocked id go with 700 or 750 psu.

Even though a 750W unit should be able to (just) power 2x 780Ti's and an OC'd CPU with a few other peripherals, you shouldn't be aiming to get a unit that can only just supply what you need. A little headroom is wise. The AX860 or another 850W-ish unit is reasonable.
