Issues with GTX 470

So in my new build I put in a GTX 470. I made the poor decision of buying a StealthXStream 2 PSU. It is 700W with I believe 4 12v rails with only 18 amps to each rail. Once I put build together everything loaded up just fine. Had issues running GPU tests and realized my computer was not detecting my video card. Looked at the box and it says it requires a minimum of 38 amps on the 12 volt rail.

Looks like my only option is to return the PSU and look at maybe getting a Corsair PSU, maybe 850 Watt?


Anyone else have the same problem and do these symptoms sound like the lack of amps is the issue here?

  1. your psu is just right for your graphics card. 18 amps for each rail means for 4 X 12 rails it is more than 38 amps on single 12 v rail (I guess). Your graphics card maybe not in correct position or maybe it's faulty. check it once again and fit it tightly into the pci x 16 slot or use powerconnector. Don't ask me coz i m least known to it.
  2. It was a simple driver issue. Appears to be resolved. I know these things run hot and are made to. Doing research I'm told to not let it go above 95. Running Furmark stability tests it hits 90 in about 110 seconds and I stop it. Is this abnormal? Should I be concerned?

    Ty for the quick response AtiRadeon.
  3. Furmark has been referred to as a "heat virus" by some card manufactures as it puts an unrealistic load on the GPU.
  4. An Nvidia driver issue? Who'd have guessed it!
  5. Actually cant blame Nvidia, it was a user issue. I had not installed any drivers yet. Took 20 seconds to search for, download and install the necessary drivers.

    So these temps should not alarm me? what is an alarming temp for the GTX 470

    And been wrong! [:mousemonkey:5]
  7. So Nvidia drivers don't automatically install with windows? How strange.

    The thermal limit is 105c so if you start to get too near to that under normal gaming conditions then start to worry, 65- 75 c is quite normal under load.

    Not ones supporting the GTX470 as that didn't exist at the time when W7 was released.
  10. 90c is completely normal for Furmark load testing and gaming.
