Graphics Card for a Corsair CX430W V2 PSU

Hello everyone,

I am looking to upgrade my graphics performance in this build. Only planning to upgrade the graphics and no other components as I want to keep this build under a certain budget. The only concern I have is with with the power requirements that most high end GPUs require.

To lower power consumption, (Thought I'm not sure if that makes any difference at all) I'm using:
- AMD CPU with a max TDP of 95W,
- Low power GREEN SATA HDD.
- Only one 120mm regular case exhaust fan

If I'm not mistaken, my power supply is of decent quality and is quite reliable. It's rated @ 430W with 28A (336W) on the 12V rail, and has only one 6+2 pin PCI-E power connector.

So far, I'm really leaning towards an XFX AMD RADEON 6850. I read about many people running these on Antec EarthWatts 380W/450W PSUs so I'm wondering if I would be okay with a Corsair 430W? I read that these only require 25A on the 12V rail and a single PCI-E connector.

Thanks for the input,

  1. Would there be a better graphics card which has better bang for buck (ie. value) ?
  2. choose hd 6850 this will improve your system more than 9600gso otherwise according to your budget build is nice!

    This is a very helpful post for future reference.
  4. Thanks for the replies

    That is a very helpful resource and I will keep note of that for future reference.

    The most powerful GPUs which I think could be supported by my PSU, anything more powerful would put alot of strain on my PSU, I think.

    AMD RADEON HD 6850 (127 TDP) --> $130
    AMD RADEON HD 6770 (108 TDP) --> $100
    NVIDIA GEFORCE GTX 550 Ti (116 TDP) --> $100

    I guess my question is, which one of these would you consider to be the best bang for buck? Or is there a better card out there...
  5. hd 6850 is best option.
  6. The HD 6850 out of the ones you've listed, provides the best performance.
  7. Yep, but is it worth the extra $30 on your opinion? over the 6770.
  8. Yes, the $30 is well worth spent. :)
  9. Sorry to dig up an old thread, but I'm seriously looking to make a purchase in the near future so I'd like to hear some more comments before I do.

    I'm looking at an XFX RADEON HD 6850 (HD685XZCFC) for $150 (+ extra $30MIR).

    This graphics card seems to be the best bang for buck, as well as the limit (TDP of 127W) for the CX430V2 PSU that I currently have.
    Note: I do not plan to buy a new PSU for this rig... because I just bought it over the summer... and that would really be a waste of money T~T

    My concern with this card is that it requires TWO (2) PCI-E power connectors, when my PSU has only one. I have plenty of the molex-to-PCI-E adapters which I could use; and I have PLENTY of free molex headers....

    Does anyone think that this is a viable solution? Will this work in the long run?
    I've read a lot about the 6850s requiring only 1 PCI-E power connector to begin with, but I can't seem to find any of those models at a decent price...

    Thanks for your time,
