PSU for GTX 460

Hi there. I want to get a GTX 460, a MSI N460GTX CYCLONE OC 1GB, more specifically.

I have a 500W CoolerMaster PSU (specs). Would that be enough?

It claims to have 18A + 18A on 12V. This page says the card requires 24A on the 12V rail, so I'd be ok? But the manual I found at MSI's website says "Minimum 450W or greater system power supply (with a minimum 12V current rating of 38A) is recommended" - then I'm not ok.


Do I need a bigger PSU? Thanks a lot.

  1. yepp totally.. i have coolermasters 500 earthwatts psu and palits sonic platinum edition of gtx 460 no probs!!
  2. Really not the best PSU, for that matter, not even average. But it will do - probably.
  3. .... try going in for the earthwatts edition or the crosair's range they rock
  4. It also depends on what else you have connected. i.e, CPU, number of HD's, DVD's USB devices etc. I would think 500W would be the minimum. Also even if the 500W is doing the job as in the posts above it will be working really hard under load and therefore may reduce the life of the PSU. If you are in the market for a new one i'd go at least 750W.
  5. There's absolutely nothing wrong with your PSU, and it will do a good job keeping your system working. Remember, that 450W recommendation by the manufacturer is the total system power measurement average, taking into account the typical components -mobo, CPU, hard drives, etc - not what is actually needed by the card itself. So, your 500W PSU has a bit of positive tolerance there. Only thing is that PSUs rarely provide the advertised power, and it's hard to tell, but, you're using a reputable PSU so it should be all good. That said, it might not be such a bad idea to listen to what others have to say, and consider getting a PSU that will not only meet your needs, but will do so with efficiency and longevity. Stressing the PSU is never a good thing, even if it can tolerate it, it will only do so for a little while. So, as soon as you have the cash (if that's the issue), invest in something better.
  6. dude you need 24 amps for that gpu and your psu offers 18 ... so that means your psu is old or just now high end , get something better!
  7. lol stfu i have a 450 watt psu from corsair.. rated for 32 amps on the 12 volt rail runs gtx 460 and phenom x4 955 overlocked to 3.6ghz plus a gpu overclock with 2 hdds and a dvd drive with a high end mother board.. now till me thats childish behavior... i know things from experience not from paper *** like you do
  8. lol i dont think im a god in computer nor my system is the best , thats all i can afford , and im just showing how a good quality psu compares to a low quality one... your the one barging here and talking nonsense
  9. wall thats problem solved... sum1 close this thread down
  10. @bushnaq you are wrong. He has 18a on one and 18a on second rail. So in total it is 36a! And GTX 460 requires for hole pc system (not only the card) 24a. And GTX 460 consume with hole pc system 331W in max load! So he should be just fine! Please inform better.

    EDIT: 18a on one and 18a on second rail is only 30a, because v12 rails are not additive! 360W divided by 12V equals 30A not 36A. Sorry guys, thanks delluser1 for correcting me!
  11. @PsychoSaysDie Sure, Cooler Master don't make best PSU's on the market, but to say that it makes garbage i must say that i strongly disagree with you!

    Almost every brand has it up and down series of products! Some series are better, and some are not that great, that is just how life is and we all have to accept that fact.

    CM eXtreme and GX are maybe not that great series of CM PSU's, but for example Real Power Pro and Silent Pro Gold series are...

    Be more objective. Don't make such a harsh statements, it's not good for your reputation. I gave you friendly advice, so please take no offense...
  12. No offence but Adam already stated that their GX series were not the best but the Silent Pro Gold is a great PSU as is the Previous Silent Pro.

    Also the PSU get a big hit at value, otherwise they could get 10/10
  13. @PsychoSaysDie Don't worry, i have done my readings long time ago, and still do, but thanks for link.

    You need to listen more friend, because i already told you that CM GX series is not that good!

    To judge hole brand for one mistake is sry, but very stupid. I will not argue with you about this! I will not repeat myself! Read again my previous post and please read more reviews about other CM (successful) series of PSU.

    Thank you VGKitov.
  14. Adam ( I suppose :) ) I was thinking, would a Silent Pro 700W (Not Gold) be able to power two Sapphire HD6850 in CrossFire.
    I think of getting one now and another one later, so capacitator aging is also a problem.

    OP Sorry, I think your question is already answerd so :)

    PS You are welcome ;)

  15. CM Silent Pro 700W is qood psu!

    It has 600 Watts with 50A for v12+ rail. That should be enough.

    Btw HD 6850 card is not to much power hungry and two HD 6850 in CrossFire will consume 390W max for hole pc system! Maybe a little more if you have more devices. http://www.tweaktown.com/reviews/3602/his_radeon_hd_6850_1gb_video_card_in_crossfire/index17.html

    So the answer is, yes! ;) HI Viktor! Best friend for hardware man could have! :hello: :D
  16. Yeah, just wanted someone else's opinion. I have read some reviews about it and it seems like a great Silent (I like low temps, but silence is also important) PSU. And it's modular with very strange flat cables which should also help with the airflow in the case :D

    Thanks ;)

    :hello: Hi Adam (right ?) it's always nice to meet an person with who you can have an inteligent conversation (well im typing so conversation isn't right :D )

    Hmm.
    You do know that the rails are not additive, 18+18 only equals 30 in this case.

    360 watt max output under the rail ratings, 360w/12v = 30a

    I have google it out (to check your statement) And yes, you are right, v12 rails are not additive!! Here is a link that explains everything about PSU's and rails... http://www.jonnyguru.com/forums/showthread.php?t=1036

    Btw, my PSU have 360W for three v12+ rails. One is 12A, Second is also 12A, and third is 6A. So, 12A+12A+6A=30A for all 3 v12+ rails, and 30A * 12V = 360W, so i thought this rule (additive rails) works for all PSU's. But this is case only for my PSU CM Real Power 550W (SLI certified) model, and NOT for all PSU's!

    Thank you very much delluser1! You opened my eyes even more! Thanks.

    Btw, my PSU have 360W for three v12+ rails. One is 12A, Second is also 12A, and third is 6A. So i guess, 12A+12A+6A=30A for all 3 v12+ rails. 30A * 12V = 360W

    So can you please explain to me, how can v12 rails are NOT additive?

    My PSU is CM Real Power 550W (SLI certified)

    Read your label, those are the continuous ratings.
    How they came up with thier formula for continuous ratings I don't know, but the peak rating is what each rail can handle individually and is generally set slightly higher.
    Been around awhile, read that link long ago.
  24. I have read my label and i know that those are the continuous ratings. I also know that peak rating is what each rail can handle. I love to work with continuous (safe) ratings. :)

    And i didn't post that link just for you... ;)

    Thanks again delluser1 i really appreciate it!
  25. I have used 500w coolermaster psus that could'nt even run a 5770, you should def spend the 60-80 dollars on a solid and reliable 500-600w psu imo, damn kids in here are ignorant as hell! malmental definatley knows what he is talking about, I've seen him giving good advice on here forever, anyways for the op I would get a new PSU.

    Some series of the CM PSU's are not very good.

    Like the GX's, eXtreme Power, Elite Power- BAD

    The Silent Pro's and the Real Power are good I thing.
  32. Ooo... I see... my friends are buy 550GX CM... and use GTX 460 so far good when play game and do a homework... Emmm.. did i need to advise him to change that PSU... cause there is no problem are appear right now....

    If it works stay with it.

    If you experience some problems, then you could change it, but I don't think that the GX550 is that bad.

    I agree, GX550 is not that bad. But hey, some people here are ready to pay hundred bucks more just for 1% better fps in games, or just so they can say hey i have popular brand so am cool. :sarcastic: Maybe am the living example Viktor(e), you know me bre.. :D jk Even am not that crazy... :pt1cable:

    Time to lock this, too much spam... :)
  35. I don't know about you guys but I judge my psu by their reliability, if one brand fails it means they let a quality escape their QA process which means their quality is not good because they let garbage through.

    And cooler master is crap, from my experience.
