  1. What is the brand/model or specs of your 600W psu?

    Is the video card new or used?

    The videocard is Brand New

    Power Supply specs :I dont understand much about this numbers but this is what I found on it

    +5Vcc +12Vcc -12Vcc +3,3Vcc +5CSB

    600W 60A 36A 0,8A 36A 2A
  3. have u tried with the driver which came with the card?
  4. The PSU's label certainly looks sufficient, but what brand/model is it? The label could always be a lie, and knowing the brand and model will help.
  5. It's your PSU, i think
  6. could be the PSU.... maybe. 600w and a 36A 12V rail might not be enought for it, especially if it isn't well constructed. I would think it would at least boot though, maybe I am wrong. If you had another PSU to test with it would be helpful, but I know that probably isn't in the cards.

    Is the PSU new? what brand is it? any links to the item?
