Dear All
Thank you for taking time to look into my request.

I am trying to build a system to be used for render
My configuration is
CPU: Intel Xeon E5-2660 2.2 ( dual processor )
Motherboard: Asus Z9PE-D8 WS
RAM: 32GB ECC DDR3,1866 MHz
Case: Thermaltake Chaser A71 Full Tower
Power Supply: Silent Pro M2 1500W

My Question is that i am planning to use 4 cards of Asus Nvidia gtx titan 6GB

i have read that each card when used at its maximum, uses 350W

The question is:
will a 1500 watt power supply be enough, or is there any other way to maximize power supplies
considering that, i might upgrade to newer cards later on if they become available.

like nvidia geforce titan Z

i hope i was clear with what i need and thank you for trying to help
 
I'd suggest you get 2 Titan Black Edition cards instead of a TitanZ card -- the card is priced at $3000 - and you'll save $1000 by going with dual Titan Black cards and get same performance.
The Titan Black card uses 250W power at full load.
2 processors of yours will take 95x2 = 190W.

And a Titan Z card will consume 350W if you decide to take it.

Assuming the rest of your system consumes 150W,

2 Titan Black cards - 850W power supply
4 Titan Black cards - 1500W power supply
2 Titan Z cards(you cannot get 4 of these as they're dual GPU) - 1000W power supply.

You could also consider a Quadro K6000, it has 12GB of RAM, and you'll get twice the usable RAM of any of these GPUs. It's $3500 however.

thanks for looking into my case

i believe that your answer helps deciding in what i want.
i already got 4 titan gtx cards and planning to make few more systems
my target is to put as much as possible graphic cards in each system since i can use them all together as a render farm.
my main bottleneck is the power supply
for now i believe the 1500W should be enough as per the current calculations.

thank you again for your response
Regards
