Best (FAST) PCI-E Card for a 18 amp on 12v line PSU

Hello Folks,

This is my first e-mail here, but I'm pretty sure it will not be the last.
I'm trying to buy the best video card available to my PSU. I have shipping problems so, getting a new PSU is for now, out of the question.
I bought this Thermaltake Purepower 430w without deeply searching at the WEB, as I do usually. Later I found that's a real crappy one that can only supply 18 amperes on the 12v line.
I'm using it on a Asrock 4coredual-sata2 motherboard with a Q6600. My old 6800gt AGP is dead, and now I need to find a good pci-e replacement.
I friend of mine will buy the card on newegg and ship it to me. I can spend even around 200 USD but I need to make sure that my PSU can handle it.
My 1st option is for nvidia, most because of Linux support (and even osx86).
For the price, I think I could even get a GTX 260, but I'm pretty sure it will blow my PSU! :)

I only found some information about amps on the EVGA website.

This one uses the newer processor made with 55un. And EVGA wrote that it could be used with a 18amp psu. Unfortunately it's now deactivated...
Someone can give me other (and maybe faster) options?

Thanks in Advance...

  1. If you are still having an agp-slot motherboard, these cards won't work on yours.
    Get an agp card if you don't want to upgrade your motherboard too.

    The same card for pci-e is a little over half its price.
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814131096
    It would work on that psu.

    Just saw it has pci-e too but only at x4. So it would seriously hamper pci-e graphics card.
  2. Your psu is as you say real crappy
    http://www.hardwaresecrets.com/article/332

    I wouldn't trust it with a 9600 GT, it will never power any GTX260.
  3. Basically you are looking for anything that dosent need extra power from a connecter. The Fastest card that takes all its power from the PCIE slot is the HD4670, Its good for monitors of up to around 19". You may need to check for compatability with the motherboard some cards need a bios update to work with that board. The fact that its not a full X16 Pcie bus will haev very little impact on your performance and the differance will be noticable.

  4. Thanks. I'm reading that post.
    BTW, what about this:

    "Graphics card upgrades - we know that the pci-e slot isn't 16x
    This presents a problem to NVidia, so seek out ATI cards."

    Why? Is there any nvidia alternative?

    Just now I'm starting to understand the ATI terminology. I left ATI since by good and old 9700.
    looks like the high-end ones are xy70, right?
    And what the y means? I saw some reviews saying that the 4830 is way better than the 4670. What's the catch?

    And what about the 3870? Isn't better than the 4670?

    what about this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102818

    DDR4 sounds great.


    Anyway, my only concern is: Limited Linux drivers (proprietary) and not sure if it's compatible with OSX (osx86).

    Well, thanks for the advice.
  5. Ok well the thing is Nvidia cards dont use the limited bandwidth anywhere near as well as the ATI cards do.
    Could you use an Nvidia card instead well yes but as said its not the best idea with your Motherboard but then if its a case of a card with good driver support that is slower, or a faster card that dosent work properly then its the slower card every time as far as im concerned.
    Any card that dosent use an extra power connector would be fine, im not that up on Nvidia cards that dont use extra power so cant recomend.
    Yes its a 128 bit interface but that isnt a problem unless you want to run a screen bigger than 19"
    GDDR4 isnt that big a differance over GDDR3 given the choice as long as its not costing extra then get the GDDR4 card but if its extra stick with the GDDR3
    I dont know much about Linux or OSX so again im afraid i cant really coment.

    Hope thats helpfull

  6. Well, I was browsing and I found two things:
    1) 4670 is way faster than the 9500gt
    2) 4670 is not yet supported by OSX86
    3) Maybe ATI is working with Novell to build better open source drivers to it's products

    So, it's a tough decision...
    Maybe I should bet on it. It's a good price $90...

    And what about the 4830? Draws too much power from my crappy PSU?

  8. Unless you are running a bigger screen than a 19" a 4830 isnt really going to be needed. They are made on the same board as a 4850 (well not all of them but most are). As such they use the same amount of power, some of them are said to be defective 4870 chips which is why they run on the same power layout.

  9. yep yep

    atleast u should get a 600w PSU :)
  10. Well, my monitor is a 19" Samsung that's only capable of 1440x900. Probably the 4670 should be just fine then.

    Now my only concern is related to OSX86. On Linux I think I can live with closed source drivers for a while.

    Damn Thermaltake!!! I had the money to get a GTX260!!!!


    Someone can please help me with this list:

    Mactronix,

    Do you think I would experience any problems if I use a Geforce 9500 on my crappy 4coredual-Sata2 and my crappy thermaltake purepower?
  12. The His card is my personal preferance http://www.newegg.com/Product/Product.aspx?Item=N82E16814161252

    I have used His a lot and they are very decent cards in my experiance its factory overclocked and should go further if you want.

    This card is a steal if the rebate works as it seems
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814125244

    There is nothing wrong with your board, the fact that its not X16 wont make a noticable differance to you.
    The 9500 is roughly 20% slower than the 4670 and i couldnt say for sure how it would perform on the reduced bus.

    Mactronix
  13. Yep. I googled some benchmarks. It's quite impressive the difference.
    Anyway, shouldn't be better a card with 1gb?
    BTW, I can't be benefited from Mail-In rebates... :(
  14. No 1gb is a bit of a sales ploy in this case.
    The extra Ram would only be of use at higher resolutions or when playing games with a heavy texture load.
    The actual differance would be in single figures FPS wise between the 512mb and 1gb cards.
    The 4670 dosent have the muscle to push those kinds of resolutions anyway.
    If you plan to keep the card for a good couple of years then it may be worth getting a 1gb card as a kind of proofing against future games needing more Vram. But dont pay a lot extra for it expecting better performance because it wont be there.

  15. I'll get the one you suggested: HIS Hightech H467QT512P Radeon HD 4670 IceQ Turbo 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
    Overclocked to 780MHz and fast, quiet IceQ Turbo

    And, let's wait for SNOW LEOPARD! it'll probably support it...
    I Hope

    BTW, OSX on regular x86 is really nice!
    After it's working, you get that feeling that you got a $2k Mac pro for free...
  16. 1.5 year later... 4670 runs great, but... What can I get now (still not using extra power from the PSU). Something from NVIDIA this time? 5770 maybe?
