    Its a 50/50 chance you lost everything including the RAM and CPU. It all depends if the "kill switch" circuit tripped before the damage was done. Somehow I think you are screwed since it turned off after the fireworks.

    Have any free SATA ports on your "server" to test your drives? Might as well get that out of the way and start figuring out what (if anything) got taken out.

    Bummer. Since you said the fireworks were pretty good I think I'll stand by my guess that the primary side blew as it typically operates at 400V. Good luck with your stuff and while any PSU can catastrophically fail, this should be a reminder to stay away from cheap PSUs for anything you really care about. Gave my mom my Seasonic X750 even though she just has an FX-8150 and a GT 440 because her computer runs a RAID 5 array with lots of backups and stuff we absolutely do not want to lose.

    What about the motherboard does your server PSU have the right connections to test it if so you might be able to test the motherboard and ram with your server PSU

    I have had excellent PSUs fail also. It is probably better to do research on a model rather than a brand.

    Of course. I wasn't saying one brand or another. Just a GOOD PSU. The PSU could be made by the Nigerian cub scouts. I don't care if its high quality.

    Higher-end PSU's will protect the system when the PSU itself fails though. All those additional protection systems pay off eventually.

    No.

    3770K @ 4.9GHz 1.5v
    2 7970's @ 1200/1800 1,3x volts (maybe 1700, the clocks I almost beat your 3 cards with in 3d11, LOL!)

    = 735W AT THE WALL (PEAK) with a 90% efficient PSU...(so ~660W at the PSU - his clocks he is obviously using less power)

    Think about it for a second. Power on these cards are 210W? *20% power limit increase = 250W MAX each. CPU is 77W and I wouldnt imagine breaks 100W at the wall at his settings...

    Seasonic X750 (or Corsair AX) would be perfect, or 850W if you are a paranoid android. A 1.2KW PSU for that setup is just throwing money down the toilet to me.

    As far as a link for quality PSU's we have this: http://www.overclockers.com/forums/showthread.php?t=589708

    I've had good results from Thermaltake Toughpower, Enermax, and Antec. My longest lasting PSU was from Silverstone, lasted a good 6 years of heavy use before popping.

    I'm currently running a Enermax 1200 and it's been great, nice and quiet.

    I'm joining Jstn7477 in assuming that the primary went out. It's usually the bias resistors and primary switchers that go down in flames. When the primary dies, in most cases the secondary simply loses power, and from the attached components' standpoint, the power supply appears to fade out into off-state. I don't think you lost anything but the PSU here.

    For your configuration, I'd go with the X-850 and call it a day.

    a true 850w quality psu is def enough, 750w not really as you would be running it closer to 100% than you want to. I would suggest you look at jonnyguru.com for psu reviews. I personally like that xfx 80 plus silver 750/850w ones or the hx850. use them as an example of what you would want for a power supply

    I just went over the numbers...:D

    660W of 750W is 88% of capacity.... and his clocks all around were less. I would have to imagine no more than 600W (id venture to guess 500W actual really) actual at his settings putting that at 80%. Perfectly fine. My X-750 didnt even spin up audibly rocking a load like that (that was 2 580's though).

    As another reference point, 4GHz CPU(1.2v) and 1180/1500 clocks... 508W at the wall in 3D11.

    Also, that link I provided, the PSU's come from only approved sites, JG, [H], and OCF itself since they test properly (actually I think TPU is in there too).

    Again it depends on what you mean. A Corsair AX 650 or a Platimax or a Seasonix X-650 or something would sure be sweet but a Corsair CX/GS or Seasonic S12-II does the job.

    Please don't buy PSU's based on that. It's not certain it will and it's a pointless ... point? I like crmaris stance.

    Damned straight! JG and TPU does the best PSU reviews.

    You underestimate the max power draws

    http://www.techpowerup.com/reviews/HIS/HD_7970_X_Turbo/26.html

    Maximum is at 348W for his clocks here

    http://www.techpowerup.com/reviews/Palit/GeForce_GTX_570_Sonic_Platinum/26.html

    His exact card is 325W max here

    http://www.bit-tech.net/hardware/2012/04/23/intel-core-i7-3770k-review/8

    OCed seems to be about 80W more for a 3770k so you can assume 125-150W after OC

    Total of that is 800-825W + like 25~50W for the rest of the system I guess? That actually totals around 850W right there

    Maybe your measurements were not done when truly maxing out your CPU and GPUs

    Don't forget when using PSU calc's to select 100% load and minimum 5% capacitor aging (I use 15%)

    I always add 100w - 150w on top of the calc reccomendations, no PSU failures to date :eek: Knock on wood

    Noone uses their system at max power draw, but I just was pointing out that a 750W PSU is not sufficient for your build. Even though max power draw is around 800-850W, I would still say 850W PSU is enough because realistically you'll probably max out around the 725-750W area

    In my experience, a good PSU should last around 6 years of 24/7 without to much problem or 8-10 years of 8-10 hours a day. A great awesome psu usually can do 8-10 years of 24/7. But for that to happen you usually want to limit your maximum power draw (not actual max, the max you would realistically do) to 80% of the PSUs capacity, if you REALLY want it to last that long you take the actual max.

    So if your realistic max power draw is 700W, you'd want 875W. I'm assuming you don't mind if your PSU doesn't last 8+ years so 850W quality PSU does the job great

    thats why i want the most realiable 1kw psu so i have head room, and can upgrade later on, im probably going to have 3 gpus in here hd8970, 7970 and gtx 570^^

    haha sounds good. Do look at jonnyguru.com so you can judge for yourself and not just what we say

    I base myself of these 3 reviews to understand what a good psu is


    I especially like low ripple and low Voltage fluctiation (ie: less than 1% on the 12V rail? HELL YEAH)

    damn it now I am going to check out of curiosity lol
