    PSU causing artifacts?

    Would an underated psu cause artifacting on a radeon 9700 pro. Basically I am getting intermittent artifacts on a 9700 pro. Do you think it is because I am only using a 250watt psu?

    Possible I guess, but more likely to be overheating/overclocking.
    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    What exact PSU is it?

    Unless it's a high quality model, with enough current, its not good to run a 9700pro on it. You could damage the card (or maybe already have).

    It is a dell standard 250w psu that came with the dimension 3000.

    Yep, psu for sure. I'm surprised you don't get random reboots with it...

    I dont get it though how a psu can cause artifacting, would it also affect the overclocking potential of the card. I have a few days left warranty on the card (it is a retek refurb) and do not want to send it back and then they test it and find nothing wrong with it. Thanks for the replies by the way.

    The as the current draw reaches the limit for the PSU, the crappier the current quality will get. If it is a cheap dell PSU the quality of the power probably want great in the first place. If the voltage is spiking and saging all over it can casue problems.

    Yes, it can have an effect on the overclocking potential of the card.
