    No - not enough. A system with a gtx 770 requires 42 - +12v amps,
    your Aerocool has only 35 (and that's if it actaually delivers it's rated specs),
    If you are going to run a 770, you need to upgrade your PSU.

    you are fine .. no need to upgrade the power at all

    Wrong. that 42 on 12 V is not for GPU only

    42 * 12 = 504 watts

    does GTX 770 need 504 watts ?

    it is just 230 watts
  4. Best answer
    your CPU is 95 watts on rail 12 V and the GTX 770 is 230 watts .. total 325Watt , if you overclock will need 100 watt more , you are ok with head room . your power has 430watts on rail 12 , the rest is enough for the harddisk and the DVD and the fans and the Chipset dont worry .. you are OK !

    Hi again - just to reiterate - your system requires 42 - +12v amps and
    your PSU has 35.

    If you are going to use the 770 with that psu make sure Gigabyte has a good RMA policy.
    I fried a 770 with a 620w that met the specifications, i ended up having the buy a new psu and rma my card. Fortunately EVGA has a good policy. The thing is, you are buying a high end card, you should use a higher end psu, no point in being cheap or lazy when it comes to a $400+ GPU.

    Hi again - Of those two, I would go with the Corsair 600w as it has 46 - +12v amps
    to the 43 of the Aerocool. Also, Aerocool has a poor reputation for PSU's.

    wrong , this is a RECOMMENDED , that is , it takes in account , ALL SLOTS occupied , 4 or more Harddrives , andmany other factors like CPU 150 watts etc to be on the SAFE SIDE.

    and when you talk with expert you respect yourself and dont say "run your mouth " Comprende ?
  11. Calculate the WATT yourself , dont follow RECOMMENDATION , there are CPU from 17 watts to 150 watts ... so it is Different , not FIXED .

    when they say "Recommended" the use HIGHEST possible CPU , that is 150 watts , and MORE Harddrives and etc ..

    people who dont know about Electronics follow the Recommendation blindly and show off as fake experts.

    have a nice day .

    Bottom line , Calculate your WATT by your self ,using YOUR ITEMS ..

    Hi - If Nvidia, Gigabyte, realhardtechx, the MSI site I linked, then I think you
    should heed their advice. I would hate to see you not get warrany coverage
    for not having the minimum power requirement.

    Also keep mind this is assuming the aerocool psu can output anywhere close to its rating. I am not making assumptions on the quality of that PSU and I recommend replacing it even if you are no where near its limit. I don't trust aerocool at all.

    I had fans in there. Dunno how much mobo chipset uses or what rail its on. HDDs use either the 3.3 or 5v rail I can't remember which.

    HDD 2.5 use 5 volt , 3.5 use both 5 and 12 V , 12 for motor and 5 for board :D

    put 10w for each hd and chipset they range from 10 watts to 50 watts so put 50 :D
  19. http://www.thermaltake.outervision.com/Power

    Use above link to a power calculator to get an estimate for the PSU selection.

    Beside this calculation you also have to take into account the amps on the 12V rail.
    GTX770 in worst case with PhysX enabled will be 230W at peak so this is ~19A.
    Rule of thumb in guides is to add 15A for the rest of the system so this makes 34A.
    Based on this SNA3 is correct and it is sufficient however there is little to no margin.
    These same guides also state to add 5-10A for safety and future growth.
    This you don't have with your existing PSU when you are at 100% TDP.
  20. Reading this thread has been very educational. I believe SNA3 has given a great recommendation and outstanding technical support to his conclusion. I especially liked the debunking of "recommended specs" and the folly of going completely off them.

    However, I wholeheartedly agree with Mouse that the QUALITY of psu manufacturer can be more important than its sticker wattage, and in fact this is the case most of the time. consistent, clean power from a quality psu that will not degrade too far from its purported specs can be better even if at slightly lower wattage. ie. an XFX or Seasonic 550W would unquestionably be suitable for your 770. The question is not so much whether 550w is enough (as has been shown with fancy charts and such) but if Aerocool can deliver.
  21. I would not recommend the corsair CX series, they are known to have more frequent instances of early failure and difficulty under load. Their other psu lines (modular ones and such) have no problems and don't use the cheap rails the CX ones are known for.

    Check otu XFX and Seasonic, they are at the top of the psu quality hierarchy and will be maintain their power output consistently enough to even be used in a second build. many CX psu's do not last that long.
  22. Corsair CX has a bad history of frequent RMA. I would avoid them if I were you.

    Hi - actually not a debunking per se, most of us know that Nvidia and AMD overstate the PSU
    wattage required for their cards. They do it to allow for PSU's that don't deliver their rated specs,
    and older PSU designs that don't allocate enough of their total to the +12v rail(s).

    This is why realhardtechx and others that study this very thing are better sources.

    Both of those situations are at play here, a tier 4 PSU that:
    Tier 4 - Not Recommend for stressful situations. May not be able to put out full rated power above room temperature, and may slightly fail to meet ATX specs.

    And only 35a on the +12v rail. Most quality modern 550w PSU's have between
    40 & 45 +12vamps.

    Right from Toms Hardware - figure the +12v amps needed for the GPU, in
    this case 19, add 15a for the rest of the system, and add 5a safety margin.
    That's 4a more than the OP has with a PSU that isn't likely to deliver the 35a
    in any event.

    http://www.tomshardware.com/forum/314712-28-please-read-determine-power-required

    And, of course the OP has 'k' processor, so it's highly likely he intends to OC,
    which itself will require more +12v amps.

    If we all used power consumption charts, then 95% of us would have
    280-350 PSU's, and I think you'll agree that's not the case.

The question is not so much whether 550w is enough (as has been shown with fancy charts and such) but if Aerocool can deliver.


    Hi - actually not a debunking per se, most of us know that Nvidia and AMD overstate the PSU
    wattage required for their cards. They do it to allow for PSU's that don't deliver their rated specs,
    and older PSU designs that don't allocate enough of their total to the +12v rail(s).

    This is why realhardtechx and others that study this very thing are better sources.

    Both of those situations are at play here, a tier 4 PSU that:
    Tier 4 - Not Recommend for stressful situations. May not be able to put out full rated power above room temperature, and may slightly fail to meet ATX specs.

    And only 35a on the +12v rail. Most quality modern 550w PSU's have between
    40 & 45 +12vamps.

    Right from Toms Hardware - figure the +12v amps needed for the GPU, in
    this case 19, add 15a for the rest of the system, and add 5a safety margin.
    That's 4a more than the OP has with a PSU that isn't likely to deliver the 35a
    in any event.

    http://www.tomshardware.com/forum/314712-28-please-read-determine-power-required

    And, of course the OP has 'k' processor, so it's highly likely he intends to OC,
    which itself will require more +12v amps.


    I already showed you the total power needed even with overclocking a 130 watts six cores EXTREME CPU which takes DOUBLE the watt of the Ivy ..

    now please admit you made a mistake and stop your empty arguments ...

    I will admit no such thing, the OP needs to upgrade his PSU, every knowledgeable
    and trusted resource, realhardtechx, msi, Toms Hardware, etc,
    says the same thing, you don't run that sys with 35 - +12v amps, especially a tier 4
    PSU that isn't likely to deliver it.

    The arguments aren't empty, they are all from sources that do the research
    and study this for a living.

    I talk from Experience more than 20 years in the market .. you talk from reading reviews ...

    Have a nice day ..

    you did not even bother to measure the chipset watt, not anything , you just read 12V rail and recommended and thats it ...

    anyways I said to the OP that his power is enough and I stand by what I said.
  27. For the GeForce GTX 770 NVIDIA just used the same minimum recommended PSU specs as for the GeForce GTX 780 even though the GeForce GTX 770 draws less power (~ 50 Watts less during GPU stress testing and ~ 42 Watts less during gaming based on reference design and clocked cards).

    Even NVIDIA's minimum recommended PSU specs as for the GeForce GTX 780 are overestimated based on looking at the actual measured power consumption of five different brands and models of GeForce GTX 780 cards (i.e. measured on the +3.3V & +12V power lines of the graphics card's PCI-E slot & the PCI-E Supplementary power connectors).

    The minimum system power requirement is based on a reference system configured with an Intel 3.2GHz 130 Watt TDP processor.

    Since the OP has a K suffixed CPU I can only assume that there is going to be some CPU overclocking happening.

    The Gigabyte GTX 780 WindForce OC 3 GB GDDR5 can draw 283 Watts during GPU stress testing. That would be around 23 Amps from the +12V rail(s) for the graphics card only. During gaming it should be around 19 Amps.

    If I were spec'ing a PSU for the OP's system I would be recommending a PSU that could at a minimum produce 38 Amps or more on its combined +12V rail(s) to at least be able to handle GPU stress testing. I'm not naive enough, like some graphics card review sites, to assume that users won't ever run a GPU stress testing app. I know I wouldn't want my system to reboot or shut down because of the lack of sufficient +12V rail capacity.

    If I were spec'ing it for gaming only (i.e. never running a GPU stress testing app or using it for GPGPU purposes) then 32 Amps or greater on the +12V rail(s) would be the minimum.
  28. Just uh, throwing this out there. If you can afford a 400 dollar GPU, you can afford 50-60 bucks more to not have it blow up. Not saying that PSU can't power it, just saying aerocool is trash.
  29. In general most PSU models that use Andyson as its OEM should be avoided.

    Raidmax and Ultra are two companies that come to mind because the majority of their PSU models are made by Andyson and those companies do not have a stellar reputation for their PSUs.

    Like I said earlier in this post, the majority of the time it is more important the quality of manufacturer and the parts they use than necessarily the wattage alone.

    Yeah pretty sure we all said the same thing in 18 different ways.

    OP: General consensus is, replace it, aerocool is junk~
