Hi, :)
First, sorry if my english is not correct, I'm french and not very good with the Shakespeare language.

My computer:
Case: Xilence Interceptor Pro
MB: MSI Big Bang XPower 2
CPU: i7-3930k @ 4.7GHz with Corsair H80
GPU: SLI MSI N560GTX-Ti TF3 PE (to change -->2x or 3x HD7970)
RAM: 8x4Go G.Skill Ares 1866MHz
Power Supply: Cooler Master Silent Pro Gold 1200w
SSD: Intel 520Series 180Go
HDD: Seagate Barracuda 2To


I want to change my graphic cards and watercool cpu/gpu.


Now, I explain my problem.
#1: I wonder if my Power Supply Cooler Master Silent Pro Gold 1200W will be enough to feed three HD7970 graphics card with the rest of my components?

#2: If three cards is possible, is a thermochill TA120.4 be sufficient to cool the 3 cards or just 2 cards? (I'll use a Thermochill TA 120.3 for the cpu

If you can afford all that, you can afford a nice Platinum rated 1500w PSU. Just my two cents.

1200w is more than fine for your setup, you don't need a 1500w power supply.

I ran an heavily overclocked 980x with a couple of HD 6990s and I never had any issue.

Also as a rule of thumb just assume you are going to need atleast 180mm of radiator surface per GPU, that is the minimum I'd use for each :)

Voltages:


videocards not o/c

Maybe later. If not posible for 3 cards, I'll bought later the third card with a platinum 1500w.

Why not. I can find enough space to put a second PSU.

Because it makes no sense? I use a small PSU just for the watercooling stuff though so that subsystem is always up even when my PC is shut off.
IIRC it gives an off command for the WC setup so if power to the main PSU is cut it should cut power to the secondary
