I don't believe you've mentioned the purpose of this setup. What resolution are you playing at? Are you using this strictly as a benchmark...

Yeah, that motherboard is certified for 4 way sli... But seriously? Are you sure you know what you're getting yourself in for? I hope you're running 3x1600p screens or something... And then you'll be in driver hell trying to get support for SLI and surround.
Sorry to sound cynical, I'm probably just jealous.
Good luck!

As the above have stated, you should only do 4 way SLI if you have serious need for that much power. You will require a very powerful PSU to support them, if not two, and you should expect a horrendous amount of noise. You'll likely want to water cool them if you find 4-way SLI is needed.

Tin888is,

The power draw from four 780 ti Cards will be high as said.
I don`t know what water cooling setup you are using, and the radiator size you have.
I`m hoping you have a very large case, you may have to resort to two cooling loops, and rad setup.

780 Ti 3-way SLI - On your average system the cards require you to have a 1200 Watt power supply unit as minimum.

Your looking at a hefty Psu with 1500w at least when the system is at full load, or maybe more with four 780 ti cards.

Money is obviously not a limit, but at 1500 per KWh and 4 to 5 hours a day your looking at an extra $160 to the electricity bill per month. Eats juice.

I don't believe you've mentioned the purpose of this setup. What resolution are you playing at? Are you using this strictly as a benchmark machine? You might try an extreme OC forum for help if so.

If this is for gaming, and you aren't using a 4k or higher resolution, you may find you actually lose performance going with the 3rd or 4th GPU.
