    Excellent post and if he was running 100% on both CPU and GPU, (like F@H for example) things may get closer to 800W at the wall. That said:

    The first link and result is quite odd to me. Again, power limit on the card is 20% so how can it go THAT much over? Why does that result fit between DUAL GPU cards? Doesnt make sense at all. And I would guess its a typo... should be 248W? I'll run Furmark on the card tonight and see what I get...:toast:

    The second link is Furmark... Wiz even states its an unrealistic load. When F@H on the GPU only I cant come close to that number and gaming is WAY less than that.

    In the last link, they are using an 85% efficient PSU and their results are taken from the wall and includes the entire system. So at minimum, take 45W off that value there which puts you at ~200W for the system on a load you wont reach (Prime95). Im hitting 235W at the wall F@H with a 3770K @ 4.5GHz (same system as above with both 7970's idling, water pump pumping, 6 fans (2 deltas), and 5 HDD's (2 SSD's).

    My apologies to all if I missed he was folding or something. :)

    On the other hand, have you noticed how power draw has gone down, all-round? CPU, GPU, even swiching to SSDs is lowering the total power requirements... I'd say you don't need to go above a HQ 850W unit, as in most cases when people "futureproof/leave headroom", they never use what they left aside.

    The longevity of a PSU is dictated by it's thermal design and thermal resilience. If it has a good enough, long-lasting fan, HQ japanese capacitors, and doesn't have any major hotspots (i.e. areas with insufficient airflow or heatsinking), it's bound to last 10+ years. The Seasonic PSU that I suggested is rated for 850W @ 50°C intake air temperature, 7 years 24/7 operation. So you don't really have to worry if you run it at ~800W 1-4 hours a day. Actually, you don't have to worry even if you run it at full 850W at all times, with brief excursions to above 900W.

    Yes he does fold and I stated that realistically he still wouldn't hit that 850W, but he def could get close to the 750W

    WOW that AX1200i is incredible http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=300

    gotta check the other PSUs but wow, I haven't seen that great performance ever. ofc it's probably 300$+ :/

    He folds with one card, not the entire system... but I see where it could get closer to 750W.

    850W FTW in this case.. 3 cards, go 1KW. 1.2KW is still a monumental waste of cash (@ $250 anyway). :roll:

    If I were looking for a 1KW PSU, I'd still pay up to a 100$ price premium for this... I'm just drooling over the perfectness of that PSU. It's the type of PSU that lasts 15+ years and gives you the absolute best OCs etc etc

    WARNING, I always get overkill and overspend when I know I'm getting a great product

    My 3770K and 2 x 7970's peaked at 775 watts with a watt o meter. YES

    Pushing a PSU over 90% will end up with the same result he has now. Nough said.

    What did you do with it? Gaming, stresstesting, FURMARKING?

    Full stressed. Furmark will not stress GPU's enough. I tried. 3Dmark 11 ran 775 watts at peak with 2 cards. I do run 5 x Ultra Kaze 3000RPM fans with the system too with 2 x MCP655. CPU overclocked at 4.8GHz and GPU's 1250/1600 at about 1.25 volts.

    One other thing... http://www.techpowerup.com/reviews/Gigabyte/Z77X-UP7/12.html

    96W for the CPU ONLY at 4.6GHz.

    unless you do it for 1hr+ straight or the card goes 90+C it doesn't really make a difference

    fair enough... take 25W off my calculations? lol

    idk if 1.3V is alot or not though, but seems right since he only ocs to 4.4

    max is still 325 + 350W for GPUs + 100W max for CPU + 25-50W for the rest = 800-825W

    3 x 7970's peaked at almost 1100 watts watts BTW. CPU/GPU overclocked and overvolted. It you go 3 cards, I recommend 1100 watt or higher. This will give you head room.

    Why 8970 plus 7970. You will not be able to crossfire them you know...

    LOL, that site said like 224W for the system while his said 163W. :confused:

    :laugh:

    Naaa, that 348W value has to be a typo... do you thnk that makes sense that it is landing between a 590/690/6990? I believe that card still has OCP/OVP on it...I mean even the matrix didnt test that high... or the Lightning...

    I dont know... poor TF... he has his information he needs!!! :rockout:

    Most sites said 210W for the system so idk why.

    But you agree that my calculations for max are about right yes?

    I'm crunching 24/7 on a Corsair HX850 (the older Silver rated version)

    Here's the newer Gold rated 2012 model:
    CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2...

    6x 6+2 PCIE connectors, 7 yr warranty, very good reviews on them- what's not to like :toast:

    and iirc a member here had a Corsair blow on him a few years ago and Corsair reimbursed him for some of the hardware he lost....

    He HAD a solytech 800W. He probably hit around 700 and the PSU popped. A good 800W PSU or even 750W would have been perfectly fine. That's the lesson here. And anyway don't these PSUs supposed to have overload protection?
