Selecting PSU

Hello,

I really in trouble for the psu selection between the Corsair 850wAx or Corsair 1200wAX.
I am going to overclock my processor, graphic card ,Liquid cooling for processor and also going to use many fans for the cooling system.

Configuration-

Processor :- i5 760 @4GHz (overclocked) with Corsair H100 Liquid Cooling

Graphic Card :- GTX 690 (manually overclocked)/EVGA GTX 680 Superclocked+(manually overclocking as well)

RAM :- 8GB (4x2GB) DRR3 @1333Mhz

HDD :-1TB IDE Seagate 7200rpm

Drive:- Sony DVD+RW Multi layer drive

Cabinet:-Corsair Graphite 600T White edition
>5x120mm fan set to highest rpm of fan all time
>200mm White LED fan highest rpm all time
>Integrated fan controller for controlling fans upto 4 fan limit.

3 USB ports are always used in which 2 are used for keyboard and mouse and 1 for 3D vision emitter.

System is used for gaming in 3D vision mode only.

System will be mostly working continuously for 3-4 days.

So please recommend me a psu for this system among Corsair 1200w Ax or 850w Ax.

If possible then a UPS as well.

    Typical system power consumption on i5 760 OC to 4.0Ghz = 204W you got a bunch more fans so lets add 30W to be safe =234W
    http://www.xbitlabs.com/articles/cpu/display/amd-phenom-ii-x6-1055t-overclocking_9.html#sect0

    GTX 680 = 170stock to 225w max
    http://www.tomshardware.com/reviews/geforce-gtx-680-review-benchmark,3161.html

    GTX 690 = 300 stock to 375W theoretical max TDP
    http://www.tomshardware.com/reviews/geforce-gtx-690-gk104,3188.html

    My rule of thumb is not push the PSU over 85-90% of its max rated this allows for surge and such

    234+225+375=634W

    85% of 850w is 722W

    this is all total power that I quoted most of it is +12v with some of the CPU being +3.3v and HDD being +5v. both PSU's can supply plenty of all voltages.

    so the 850w will run it just fine, but if you think you ever might go for 2x 690's then you might need more than that.

    You have added the results of 680,690 and processor giving me the output which I don't understand at all why did you did this ?Will you please explain me in detailed form.

    This is what the psu calculator is calculating for me (by extreme power supply calculator):-

    80% load -
    780 W

    With full load with addon 1 card pcie,1 HDD ,6 USB ports usage:-
    948W
    Is this psu calculator reliable for the approximation guess correctly or should add more to the values obtained?

    Using 2x680 SLI is less then or equivalent to 1x690 so the real problem is that if I add some components later on 850 will it become less for the extra components or to make it more secure I should go with 1200W but if I go with it then I think so it will be having more extra watts.

    The 690 thread was opened by my comment only and already gone with both the threads.
  3. You would be fine with the 850w, BUT... Those are both solid power supplies and will live through the life of more than one build. If you are OK with the price of the 1200w, know you have a moderately large power requirements, and want some overhead for futher upgrades... then that is the PSU for you.

    mmmm because you listed both as GPU's - thought you wer trying some weird tri SLI setup :o

    PSU calculators are rubbish! They always get you way more PSU than you need. As long as you buy a quality PSU that actually performs at specs.

    no the 680's x2 will be 240W to 450w, where a single 690 is 300w with max TDP of 375w

    Yes, I was so confused on that comment with 590 as dedicated graphic card and 680 as physx card.Really funny or say really crazy. :)
    Will you please recommend me UPS also for only cpu because I have other one for the Monitor.

    I am running this one on my gaming rig (in my SIG). I had it about 2 months now without any issues.

    That ups will be good for 850W power supply but not for 1200W.
    Will it support 1200W also?
  8. 850 AX is enough but if you wanna go with AX1200 its fine for future but in future gpu card power getting lower by cards i would say 1050HX is good

    Going that big is costly and requires a NEMA 5-20 power outlet (20A).
    http://www.newegg.com/Product/Product.aspx?Item=N82E16842102068

    this is the only one I see that is NEMA 5-15 (15A)
    http://www.newegg.com/Product/Product.aspx?Item=N82E16842107014
    I have no experience with it, but it has 2 favorable reviews.

    I want gold series PSU only to be future proof.

    Any UPS suggestions for me ?

    I like your UPS and 2nd one seems to be more satisfying for me then the 1st one.

    here is a hands on review of the UPS

    http://www.wegotserved.com/2011/09/28/hands-optiups-ts2250b-ups/

    seems like a good value for a high wattage UPS

    Let me try this one if any problem or other situation arrives then their will be another thread on this to give warning to others.

    If nothing happens then it would be fine.
  22. Please guys go through this whole thread once and give me the final decision between 850WAx or 1200WAx.

    No price issue.

    You took my post wrongly.

    I liked your suggestion and I will go with it.

    This UPS is not tested by any one of the members on the forum which I am going to test may be and post the results on another thread with better support for this product.

    May be now you got my thread.
