I think you might be pushing it a bit as the card will consume around 165 Watts itself. (click here,3542-22.html). It just might put the power supply unit on to running at around full capacity and result in a problem along the line. If I were you I would install a more powerful PSU but then again you have nothing to lose by trying it. If the PSU burns out then you will have your answer but that has its own risks in that it might take some other component with it. I would not risk it personally.
