What wattage should I get

Not looking for comments on why or what grahpics cards.

I am making a build with the Maximus extreme, looking to support up to 8 hard drives, and at least 3x sli on Titan, also the Haswell processor, and maybe future Graphics cards 3 way.

I believe with 3 way titan 8 hard drives, a water pump, and 12-14 fans, 1000w should be enough is that correct? so if I go with a 1200w power supply it should work for Haswell and next gen 3 way sli?
 
1000-1200 watts should be what you're looking at for that system. I would go for a 1200 watt if you plan on overclocking on water.
 
Might as well go all out and get one of those Enermax Platimax 1350's. [H] gave them a Gold Award and 1350 watts would certainly be enough juice to power anything you could want to do.
 
Any of the above brands should be fine. Probably best to go a bit above 1000w to ensure your future needs are met.
 
I was looking at a be quiet DARK POWER PRO 10 1200w I'm trying to build a Very quiet system. Plenty of radiator space, I just havent decided how much I want to spend on Graphics cards yet, and am waiting the few weeks for the haswell annoucement/release as that should drop the price of CPu's and give me a look at what the new motherboards are offering. More choices/options always better.
 
1000+ watt power supplies are going to be anything but silent, just due to the sheer amount of heat they have to dissipate at full load. You'll want to get the most efficient one you can afford. The more efficient they are, the less heat they put out and the quieter it'll be (in general).
 
I'm attempting to build as silent as possible build while idle, While keeping the noise to acceptable levels under full load. From what I've read the Be quiet is gold rated and has received some great reviews as it includes extra cables to support different configurations, fan control through the power supply for PWM based on draw, which I plan to use for the case fans, and an excellent fan that is indeed quiet under normal use.
I plan on Radiator fans through a control based on Heat on the CPU/GPU with temp sensors, If I go to a review here for the 3 way titan it shows 920w on full load is 920 watts, and the 7970/680 is 200 watts lower. So I'm thinking for this gen 1200 watt power supply will cover me even if I do a few upgrades, I guess I will have to wait for the next gen reviews to come out to find out what the pull will be from haswell and the 800 seires
 
GPUs are maxed out around 250 watt TDP for top end cards. More than that would require much bigger cards with more expensive heatsinks, so I expect future cards, at least for the next 2-3 generations, to have the same 250 watt TDP ceiling.

I would go for a Platinum rated power supply, since cost doesn't seem to be a concern for you, and fan speed profile should be based on the internal temperature of the PSU, not load. I'm fairly certain that most, if not all, high quality power supplies use temperature to control the speed of the fan. I would recommend that you look into the Enermax Platimax 1350/1200 and PC Power & Cooling MK III 1200. I don't know where you're buying from, but I would also consider the Lepa G1600, which retails in the US for around the same price as the be quiet 1200. In fact, the G1600 is currently cheaper on Newegg than the be quiet, and has a similar platform to the excellent Platimax.

For the case fans, I would use a digital fan controller with its own temperature sensors and automatic fan adjustment. A good one is the Lamptron FC Touch. Another good one is the Bitfenix Recon, which has an internal USB connector so that you can control it from inside Windows.
 
I was planning on the Recon for the build, and the fan speed profile based on load would be the case fans connected to the PSU not the PSU fan itself. My only issue with hooking up case fans to Recon was that I would be running 8 radiator fans and wanted to connect them to the Recon and read you shouldnt hook up more then 2 fans to each connector due to its supply and it had 4 connectors. Seeing as the CPU/mosfet/Gpu would be liquid cooled, I am not as concerned with how accurately the case fans run as long as there is some control.
 
Depends on the fans you're running. If you're running non-LED sub-2000 RPM fans, you can safely hook up 4-5 of them on a single channel.
 
If you are grabbing 3 titans then get the biggest psu you can get with a good rating. Budget doesnt sound like an issue with those gpu's.
