Hey i was thinking of getting 2x Titan Z's but no review is up about the Titan Z in SLI that shows off the power draw only gaming performance.

I know a single Titan Z draws up to 580watts when max load is on it but is it simple as adding up the watts together ? I've had 2x Graphics cards before and looked at a bunch of Graphic Card reviews especially Crossfire/SLI reviews and almost never the single card when times 2x with the watts a single max load is never really the answer aka the R9 295X2 is 610watts max load in reviews of the single card but when crossfired its just under 1200 watts which if it was added together it would be 1220watts max load which its not

so i cant add the numbers up due to it would be inaccurate i was hoping 2x Titan Z's would use a 1200watt power supple i guess the max out put being 1050watts just a guess but also the build will have a i7 4790K and will over clock it a little have 3x SSD's 3x HDD's 4x 8Gbs 1866 Sticks of ram LED lighting and a Blueray Disc Drive

so i am not sure if all that adds up more then 150watts or not i feel a 1500watt would be a over kill for the system and its air cooled not water cooled

Hmm now that I think about it, if a single Titan Z consumes 450W peak, that x2 is 900W, plus let's say 100W for an overclocked CPU is 1000 plus 20 for each HDD and 5 for each SSD, around 60 for the motherboard and 30 for the RAM is 1165W... And considering the efficiency of the PSU, 1200W might now cut it in a very stressful power hungry situation


I suggest you get the Corsair 1500 watt power supply it's not that much more.

The 1200 watt should be enough however with a $6000+ budget for graphics cards it's doesn't seem like money is a concern.

I would wait for the Haswell e 8 core if I was building such an extreme system.

I might just go with a 1500watts i didn't want to overkill but I guess it saves me from having to buy a new power supply down the road and this build is happening at the end of this year $12,000 dose not just pop up over night but I didn't want to make it a waste either so I only wanted to get quality parts that will never need changing and a system I can make my video games on

I would only wait until February 2015 if the X99 chipset has not come out and is delayed to the end or half way through the year then I will get just what chipset is out at the time

This might be a build towards the end of the year of this year but it's only few months away and knowing before you buy doing extensive research into making the best build is always the best way to go

Purpose of this post was just to see what kinda power supply should I look at for the build
 


X99 should come out by September and will use more power than a Z97 Based Machine.
1500 watt is the way to go in my opinion.
 


I thought the X99 chipset was not being released until Q1 of 2015 ?
 


Where did you hear that rumor?
 
I really wanted to wait for maxwell but just because i be making a $12,000 pc in december 2014 - January 2015 don't mean i might not make a brand new maxwell system in 2015 just for friends to come over n play because really it might be hard to let someone play my $12,000 system lol

its been 2 years to this date since i made my first pc and its still running good just with a different graphics card so i think 2 and a half years is long enough for a new pc
 


The 4k monitor i already picked out is the Dell 4K IPS 32inch Monitor
 


And i cant have Maxwell because i want the Titan Z because reason i am getting both of them is because i am designing and making video games so i need what the Titan Z brings for my gaming and making video games too
 


Well I'm not building it until December of this year of Q1 2015 so the rumour mills will be running around that time if there is any word of a new improved Titan or Titan Z
 


Yea and with a Broadwell chip to add too

should be a system that will always live for a very very long time i doubt games in any future wouldn't make 2x Titan Z's give a run for its power if they can get 60fps maxed out on battlefield 4 on 4k rez there is no way for it ever being obsolete
 
It could take years before the broadwell E is available and I don't think it will be much faster than Haswell E...

"X99 platform is suggested with quad SLI because of the extra PCI express lanes and extra cores"

I sure 2 Titan Z's will be nice however I'm not sure they can deliver a solid 60 fps on all maps at 4k.
 


should check out the benchmarks http://www.digitalstormonline.com/unlocked/nvidia-gtx-titan-z-4-way-sli-benchmarks-idnum293/

and i mean the broadwel intel cpu's start coming out September - October 2014
 
My guess is that there will be dips below 60 fps on some maps, below is another review of the Titan Z.
"4k is very new and their are stills some bugs that need to be ironed out"

http://www.guru3d.com/articles_pages/nvidia_geforce_gtx_titan_z_review,16.html

I doubt broadwell will come in September or October and even if it did come out then it wouldn't be the broadwell E that you need because of your quad SLI configuration 16 pci express is not ideal in my opininon.
 


Well the motherboard i currently have selected is a 1150 and is a gigabyte board with the first and second PCIE 3.0 are both 16X and so is the 3rd but when the 4th is used the 3rd and 4th become 8x so with this board i would get 16x for both my cards aka using up first and 3rd because the Titan Z takes up 3 slots
