Ya the video card does use a lot power, and with that Prescott, your PSU is really taking a beaten on the 12v rail. Who makes your PSU?

Wait... getting the same even when booting up... that when a realize this cant be a software thing. So to make a long ass strory short, i realize that as soon as i put the video card on its own dedicated power line, it works fine. Any other items, such as hd's, dvd burner etc, and itll crap out like this. Now my question is why? My power supply is a Ultra 500watt, voltages are all within spec, in fact almost bang on. I refuse to believe that a video card requires THAT much power, im scared to run even fans on that rail else my gpu'll crash! ok, ive got a couple fans on it but still, shoudl be able to take more than that. wahts the dealio?
