Nvidia GTX 580

Hello, I have browsed this site before for information, but never actually posted anything. Anyways I had a question regarding the Nvidia GTX 580 and my power supply.

I'm looking at this card, http://www.newegg.com/Product/Product.aspx?Item=N82E16814130590&cm_re=gtx_58-0-_-14-130-590-_-Product.

I have a corsair 750W psu, I know its more than beefy enough to handle my system, my question however regards 8pin molex cords. I only have one with my PSU and the card looks like it requires an 8 pin and a 6 pin.

The card comes with an adapter(I'm assuming) that looks like this, By ag3ofshadows at 2010-11-26" class="img lazy">.

If I connect the 8pin adapter, assuming that's what it is, into the video card, and connect the 2 6pins into the adapter will that fuel my card?

Any feedback would be much appreciated!

System Specs:

OS: Win 7 x64 Pro
PSU: Corsair 750W
Mobo: Asus P6T
Proc: i7 920 @ 3.4
RAM: 6gb DDR3 1333mhz
GPU: 9800gtx+
HDD's:
OS drive: 74gb WD raptor 10k rpm
Media: 1tb WD Caviar Black
Sound card: SoundBlaster X-FI Extreme Gamer.

Thanks,
Ag3.

*edit, What do I need to do to fix my newegg link?

  1. Assuming you are not running 5 SSD with 2 DVD and Blueray burners you should be ok. I would be able to help you out more if you did tell me you system specs.
  2. Lol, all I basically wanted to know was if the cord would work the way I specified or not. But yeah I'll post em.

    Thanks.
  3. Yes the cords will work, and your powersupply has enough juice to power the system BTW.
  4. Thanks again.
  5. does 750 watt have enough power to power two gtx 580s in sli and oc a i7 950?
    cuz ill be pickin gup a i7 and a gtx 580 soon and i want to be sure i get a psu that will eventually support all my sli, oc, and fans...

    heres my setup at the moment:

    i7 950
    gtx 580
    asus x58 sabertooth
    corsair 6gb ram
    only 1 hdd (1 more hdd with an ssd in the future)
    asus super drive

    i heard psu was really important so i want to get a good one...corsair 850watt
    but if the 750watt can handle:
    i7 overclock
    dual gtx 580 in sli (maybe even triple)

    and possible oc on ram, and the gtx

    THANKS!
  6. Psyco, would my setup be alright with an additional SSD? I'm not familiar with them, and I'm not sure how much power they require. I'd imagine I'd be fine though.

    Thanks.

    @Jason: I have no idea, wait for Psyco or someone else to respond haha.

    Sadly I am sure that your PSU will not be able to power 2 GTX 580's in sli. Even if you had a 850 watt i don't think that it would be able to power it, unless you use the 850 and the 750 watt to power your system then no question asked it would be more than enough to power your system.

    You should still be alright with an SSD, they don't consume a lot of power so yes you should be fine.
  9. How does one figure out what PSU is optimal for a specific system. Like how would you determine what the minimum wattage would be for lets say a 2-Way SLI gtx 580 system with an i7 920 proc, hdd, dvd drive, and p6t mobo?

    (this is assuming that your not researching tooo much) haha.

    An easy way is to add the amount of watts each component takes under max load/ maximum watt intake. I personally do that and always add 50 watts for overclocking and get a psu that matches what my watt usage is, but always go with good brands never generic.

    Thanks for the reply! I also wanted to know the answer to ageofshadows question.

    I have another one: Will 750 watt be enough for

    i7 950 oc to 4.0ghz
    and one gtx 580?

    ill prob be upgrading to sli after two years and i dont want to drop the bucks for 850 watt if i know ill be upgrading the psu to 1000watt...

    1000watt is suitable for all the oc and sli right?

    THANKS!
  12. 1k watt will be more than enough to power 2 Nvidia GTX 580's in SLI and and your Intel i7 950 @ 4.0Ghz and you probably can OC your 580 like crazy too. So yes a 1k watt (make sure it no generic brand go with Antec or Corsair) will power your system with 2 580's in sli.
  13. So where would you find the max wattage required to run a piece of hardware at max cap? Google?
    What confuses me is the 580, on evgas website, states that it requires a minimum 600watt psu, so wouldnt 2 require 1200w? I know thats wrong, but I dont know why, any justification to help me out?

    Thanks again!
  14. You would not double it, because the original recommendation is for a COMPLETE system.
    High performance m/b and cpu / memory is considered normal to be used with a flagship GPU like the 580.
  15. Ya, i knew you wouldnt but wasnt sure why. Thanks.
  16. Ive been looking at several psu calculators over the internet and they seem to be split over the recommended psu for dual GTX 580 (used 480 cuz 580s were not registered)

    some say 850 is enough and others say 1000watt is recommended. Now can anyone can give me real life examples?

    Im trying to run dual gtx 580s, with OC cpu, and two hard drives.

    High Quality 850 will work.
    Peak is during gaming, thats just the video cards.

    THANKS! this was really helpful! I just saved myself 100USD!!!
  19. ya, go for a 850w Corsair, XFX, or Seasonic.
  20. thank goodness! I am running over budget actually...like 100 or sth...and I was totally horrified that i had to spend over 200 for a 100watt psu..

    also im not going to run dual gtx 580 right now...just in the future maybe a year or two later...

    doesnt hurt to be future proof!
  21. awesome chart.

    is it fair to say green is still adding watts to their new models and red is actually lowering watts?
