My software show numbers pretty accurate...
Input power is I think how my system really need.
12V rail when I change from 12.15 to 12.10V example AIDA64 notice exatly 0.05V change, onle numbers are little difference... But like you know sensors is always good to have voltmeter but you will see voltmeter react exactly on change/tune voltage with software on 12V rail...

It's not accurate, someone here on Geforce Titan subforum had 4 x GTX Titans in SLI running off a EVGA 1500w and it burned up on him and he was pulling like 1600w from the wall.

It's not accurate, someone here on Geforce Titan subforum had 4 x GTX Titans in SLI running off a EVGA 1500w and it burned up on him and he was pulling like 1600w from the wall.

But somehow this makes now sense to me, Guru 3d tested with 3 way -SLI and per Titan they reached approx 250 Watt. In all the other tests I read, the power consumption was the same. When we assume 1000 Watt on graphic cards, there is 500 Watt left for system. And with his OC you will never reach 500 Watt. Because of this I can't believe that he burned up his PSU.

 
well he posted here that it started sparking (the rice krispies type joke) when he was running 3dmark 11

then he posted here he is pushing the limits of the PSU with the replacement as well
 
http://forums.evga.com/fb.ashx?m=1887556
 
after that he posted he had to install a 240v breaker cause he wen't over 1600w

Hey look im 3 in the hall of fame!

By the way I love the supernova! The twelve volt regulation on some of the very first units were not that great and at my crazy power draw caused stability issues... I very happy with my new unit!

There is an easy way to find out how much Watt you use. You can buy a watt/energy meter and just plug it in.
 

 
 
You can get such meters around 30$, in my opinion a small investment compared to the costs of your hardware.

that wont cut it do you know where i can get a 230vac 20 amp unit?

Have a look on that

this meters I told you, read up to 3200 Watt, so now prob with your system.

Show your PC, if I can't buy I want to look.
What's inside 4x Titans and Intel Black Overclocked.
Clear 5000MHz - 5 GHz.

has anyone directly compared killawatt numbers to supernova numbers to see how close or otherwise they are?  Just so we all have a relative idea? I know its pretty darned important to me at the moment.  I wish I had one currently.  My psu is either faulty, or my rig is drawing an obscene amount of power.   Either way i'd love to know which.

to add insult to injury, I can corroborate your results.  My 4 titans are causing my supernova to shut down randomly during ffxiv and it wont even start furmark.  It runs ok if they aren't overclocked but the minute I put juice behind them it kills over.  
 
EVGA is sending me a new one after I cited my numbers to them, but im not confident it wil help as those were the numbers I was able to attain non shutdown.  God knows what it was pulling when it shut off.
 
supernova software in single rail shows me as drawing 1850 from the wall, 1620 or so out of the psu, and 133A.  Id imagine it doesn't take much more to kill it and who wants to run their psu that hard.  I never ever would have imagined this rig taking more than 1500w or 2x psu but /sigh atleast ill have enough power for probably every pc I ever build for the rest of my days >.<
 
I want to run OC mode as I may "just" make it with that, but I have no idea how to hook up a 220v outlet and I cant afford to hire an electrician to do so.  Not to mention they would likely think im nuts.  Im probably going to be stuck pitching a Christmas request (that I would much rather have used for a mouse/keyboard) in the hopes of keeping the rma'd unit they are sending.   I'll have to run it outside of my case until I can afford a new one but meh.
 
I find it hilarious that the haters cite the inaccuracy of the software, then move on to the quality of the psu, then tell me that a 1200w corsair would run it fine.  lol if that were the case I would gladly grovel and admit ive been wrong.... however evga should be ashamed if its charging the price it is for this unit, and barely able to do 100w over spec when a cheaper unit Is allegedly capable of 600+ over spec :P
 
anyhow, my oc on my chip is weak all things considered (I dropped my good chip on the ground sigh) and I only have 6 case fans and 1 waterpump and 1 optical drive .... 1.212 kills this psu.. I was able to run it at 1.162 problem free but god forbid I wanted to unlock it and run 1.3v ...  this psu is simply not quad sli capable in an overclocked system from what I can tell.

1500W isn"t enough for your system, you need 2000W but for the moment you cannot find this beast. Use 1500W and buy 1000W PSU. You can dedicate 1000W only for your CPU, and 1500W to your X4 TITANS. If you want to have +230V Outlet you need to buy "amplifier" or something like that to transform tour 220V ..or contact your eletrical service to buy a special subscription for 230V outlet.
 
People who say "How could it possible 1600+W with 4 titans...My answer : EASY. X4 Titans are very very hungry cards. My X3 7970lightning + i7 3930K take 1800W outlet, +1450W output, so imagine with X4 TITANS, its a HELL XD
  
I bought 1500W SUPERNOVA and sadly it was a faulty PSU :((, I send it and recieved RMA - totally "new" (some visible very little screw marks -_-" on PSU) but for the moment it works. My previous Powersupply shutdown itself when playing and idle + error Kernel Power 41. I'm sad that I bough this psu...I should went to LEPA 1600 or something better...1500W Supernova - a curse for me >_<

Please excuse me for my English, I'm french :)
 
Woow, be very careful, Your system pull 1696W so even OC MODE 1650W isn't enough for you... Try to reduce as you can yours TITANS's Overclock. Put just a official voltage + frequency and launch your system at 100% to see your power consumption. Remember Watt input is measured at wall, then you have power loss => heat so you should take care of output wattage. Normal Mode is 1500W, BUT try to not surpass 1400W. Contact your electrical service, to inquire how install 230V outlet OR install an "amplifier" convert 120V => 230-240. In France (where I live) our outlets are 220-230V BUT our electrical group send to us a little bit more Volts, so that's why I have 235-245V at outlet :). Another Solution is  : buying 1000W Power Supply to CPU, and keep 1500W NEX for your TITANS
 
Your Supernova Software is upgraded? My Unit seems to working fine ...but I'm very dissapointed. it's not a new unit but I guess "used" one because of little visible screws marks on gate, back of unit. Wow someone was stupid to put screws at gate and not in special holes. AND little physical damage on the fan in middle (on the fan's stiker just below EVGA logo). Anyway, it's a minor and it's hard to see this "damage" it's ok for me, but it make me a little sad. Anyway it's very hard to see that...
 The new unit that I recieved works great for the moment, no random shutdown at heavy load, but I need to test 2weeks or 1 month to judge this. I still hear little hissing noise when my PC is OFF, my previous 1500W NEX makes a very loud hissing noise when PC was OFF, the new one is better, BUT there is little hissing noise but I think it's NORMAL.
 
My +3,3V isn't not correct, in previous threads I saw this is because of small cables or something like that, I need to claim a new cables/screws and maybe another unit because of minor physical damage on the "NEW" UNIT from RMA.
Don't know what doing now, refund and take my money back and go to LEPA1600... or change psu, totally mad and sad

Yea I am aware I am at the upper limit. Some people say this software isn't accurate so it isnt using anything near that much. I wish I knew one way or the other.

Still waiting on my rma to ship. Placed it a few days before the holiday and it still hasn't been sent. Even if it does fix the shut downs, I will likely need another one (assuming that software reading is accurate)

Although, after hearing you say your unit shut off and replacing it fixed it, and the private message I just received from another forum member with a rig similar to mine who said the same... I'm feeling optimistic that this new unit may fix it.

Of course they could send me 2 bad ones in a row I guess lol.

I wish I could get more info out of the employees, I know damn well they know whether this is an issue with the psu (quality control or otherwise) as well as what the limits are.

I have to believe if they are just giving Vince (kingpin) toys (4xtitans) to just play with and overclock to his hearts content on, then their are several other employees with a similar system who know through and through the load put out by this sort of rig and whether or not the nex can handle it.

Why the hush hush? Some tech support/enlightenment could do this thread some justice. I'm imagining the hundreds of people googling this issue only to end up here with no solution.

Abyways, thanks for the PMs and responses so far! Hands are tied till I get this new psu one way or another :(

Thank you. Yes I know about efficiency and power loss, but just wondering to know if its normal after my previous faulty psu I'm a little bit stressed lol.

Thank you :) Yeah, all seems be working now after receiving new 1500W nex :)
About your psu, if it's still shutdown, try to find second psu (maybe your friends can give you) just to provide power to your cpu and motherboard and running your 1500W evga with titans. If your pc still shutdown, defenitly powersupply issue. :'(

new one arrives tomorrow so we shall see what happens.  ill keep ya's posted.  Anyone in this thread have a Kill-a-Watt MainMeter AND a NEX1500?  If so, please post.  I have a small request I thnk the entire community will find useful/appreciate!

An overclocked titan on load can draw up to 300 watts.  Most people use 40-60 % of PSU capacity.
