    Hi all,

    I posting this cause I really dont know if Im right in sternly replying to a certain thread on another forum about the power requirement of a gtx680.

    Here is the forum thread (im deejeta there as well)
    https://teksyndicate.com/forum/build-pc/best-energy-efficient-parts/152623

    Look I know the gtx680 is a pretty efficient card and all but to recommend a 360w unit... my jaw nearly hit the floor.
    Anyways since I dont have a gtx680 to test myself I was wondering if peeps in OCAU land could shed some light on this for me.
    The suggested unit doesnt meet the amp requirements.... Ive had gpu's in the past not even boot on low 12v amp test psu's. ie gtx480.

    With psus, it is always better to overcater than under
    Considering the pricing, I would probably not go under about 600-650w, and knowing my personal requirements, would shoot for 750+, but my requirements are unusual. 600 should be plenty

    psu's are a funny area, so many people want to save $$$ > quality

    i would suggest a decent brand around a 750-850w(650w min)
    the HX & AX series from corsair comes with 7 years warranty(8 years;1 bonus year if purchased directly from them)

    i personal use only AX series Corsair psu's .. AX850 , 2x AX1200 , 1x AX1200I

    Cheers, Alan.

    550W will be overkill even with an overclocked Haswell (more power draw than Ivy). A cheaper quality 550W like a Corsair CX would be fine.

    My 430W S12II had no problems with a 480 and 1st gen i7, a 680 draws less still.

    Most PSUs are most efficient at ~80% load, but about 50-60% load is ideal as it will be quieter on the PSU fan. Getting a 750W psu and running well below 500W will make the PSU run at its least efficient range.

    If warranty is the main reason you buy a PSU, then no one can beat Thermaltake's LIFETIME warranty.

    older power hungry cards always make people over do it on psu's its scary but on a good brand PSU u can run 2 x 680s and an overclocked pc on 600w no dramas.

    I'd say you need a 1500W at minimum, if not two. Good luck!

    Lifetime warranty means absolutely nothing. Lifetime warranty is just whatever period the manufacturer says is a reasonable lifetime of a product, and in the end they can say its 1yr, 2yr etc etc so you never actually know how long you are covered for.

    That's a limited lifetime warranty. Lifetime is lifetime, even if your replacement isn't the same one. However you may end up with a different warranty with your replacement.

    So you honestly believe it means the warranty lasts until the day you die???

    How long do you reckon lifetime warranty on some PC133 SDRAM would last for?
    Because I did an RMA this year for some.

    It's up to the manufacturer, could be 3yrs, 5yrs or 10yrs. That's the whole point, there is no fixed timeframe and the warranty does not last forever, it's up to them.

    To the OP, i'd suggest getting something decent like a Corsair AX860 so you have room to move in the future.

    For what it's worth, The gtx 680 is quite popular in ITX builds, especially in the SG05 case. Max psu available (at least when I built mine) was a 450w. I have been running mine now for about 4 months, and had zero issues.

    Just my two cents. Really should be talking about amperage and temperature derating. At that point id say for a 680 system not overclocked, 40A on the 12V rail derated is a good idea.

    i was running a 4870x2 and q9450 from a pcp&c psu 510w 34a continuous and 38a 650w peak

    gtx680 with 2600k would use half the power of that system

    my watercooled system with 2600k@4.4\7970@1100 was using ~300w at the wall while gaming

    the seasonic 360g has a 30a 12v which should be enough but the one 6\8 pin would make me hesitant to recommend it

    450-550w is the most i would typically recommend for a single gpu system but sometimes the corsair hx 650 with its 7 year warranty looks tempting when it was cheap especially if the user was purchasing from a store with a limited psu selection
