what kind of motherboard do you use?

asus extreme iv black edition this allows you to run PCI e slots in x16 x8 x8 x8

Watercooled?
If not, what temperatures you have on the cards?

Not water cooled, 82 if i run them at stock since gpu boost pumps to 82, i usually run them at 90 percent (they are the OC versions) that gives me about 1140 mhz at 75 C just to be safe.

is that too high?

I am running 4x gtx 580 with temps 75-85 degrees and they are made to get that warm.
(watercooling is probably better for longterm and for more pleasant workspace; 'it is getting hot in here')

And I chose a 1500Watt not to take any risk for a few dollars more and for future to be able and swap the 4 gpu for new ones without having to worry for the specs.
About 4 years ago I bought a machine with a little too much of everything and i could enjoy that benefit a few months ago,
when I was able to buy two Titans and just put them in the 'old' machine (for networkrendering).
So my advice is to always go for little more then needed when it is just a few bugs more and/or if you can spend ofcourse.

Greetings,

great thanks, I have a ax1500i which is 94 for percent efficient (titanium rating) and I was worried it wasn't enough
