Project: TITAN 4 !!!!

They actually don't pull that much power, not much more that 4 GTX470's

4 x 263W = 1052W and thats peak under furmark, only for the cards mind, but the rest of his system isn't going to be pushing more than a couple of hundred watts at most. Plus hes probably not peaking the cards unless he is running Furmark Benchies.
 
4 Titans = Epic, is one PSU enough for them though or do you have another tucked away some where?

Just the one PSU

I have seen a couple of guys in America running 4 Titans on a 1200w corsair and then wondering why performance was down.

The other week I measured at the wall what 3 Titans and an oced hexcore were using and it was around 1100watts. So 1500watts for 4 Titans should be plenty.
 
Today I cable tied up a load of wires, installed Win7 and ran a few benchmarks

The max TDP of 300W will bump it up if he gets all 4 GPU's running at 99% and with the 3930K/fans/pump/SSD, I expect 1400W to be doable.
 
Kapp could you run 3d mark Extreme and heaven and post the scores please.
I would very much appreciate it as i would like to dip my toe into the whole Titan scene :)
Great build log by the way.

Thanks

With 3dmark Extreme and the standard version, any more than two cards and you get negative scaling. This is a bug with the benchmark and it is the same for AMD and NVidia.

The Heaven score above is using the Extreme settings.
