    anyone had probs with Nvidia 7800gtx (Dell) and power supply. I have an Antec true power 550W and whenI put the 7800 in my machine it trips the power off. I have stripped the machine down to basics, Asus P5gdc deluxe board 3.8ghz P4 2gb of Ram and one hard drive but the same thing happens.
    Surely 550W should be enough. any ideas would be welcome.

    That should be more than enough power, how are you distributing the power for the drives and the SLi connector for the 7800 over the two rails on the PSU??

    Try running the 7800 on its own rail

    Im on my third antec neo he 550watt psu. Fist one was ok for about a month or so...got home one day and the computer wouldnt turn on. The motherboard was getting power but it wouldnt turn on(it must have been either the 24 pin power connector or the 4 pin) Second one first tried it...and the same thing happened. At this time I was only using one x1900 xtx(now im using crossfire) My third one touch wood seems ok. Im using crossfire and all is well.
    I dont know if this makes a difference but on the new one,it says europe on the box.on the two that failed it didnt..who knows.

    Circuits that supply power at a certain voltage.
