    Angry eVGA 7900 gt problems in Dell8400

    Upon initial installation my monitor goes into power saving mode and won't come out of it.As soon as I boot up I get a blank screen.When I put my X800 back in everything is fine. I uninstalled all ATI software prior to installing the 7900 and ran driver cleaner.I made sure that the card was seated and that the PCI-e power cable was connected.I have ran a xfx 7800gt oc in this computer with no problems at all.Shouldn't this one also work? I am lost.

    eVGA vs BFG 7900 in Dell 8400

    eVGA says that I don't have enough amps but my psu is rated 12v@18a +12v@18a . Shouldn't that be enough to power it? Plus my XFX 7800 gtoc ran fine and it had the same min specs and it ran fine. How could it power up and the eVGA not. I have noticed that the BFG 7900gt has a 350w min rating and 12v@20 amp, maybe it would run in my Dell . Are BFG cards good? I heard all these great things about eVGA so I wanted to try them but I get a hundred different suggestions from different support people and some misinformation like you can't upgrade the power supply in the Dell when I know that this is false.Just seems like they are fishing.

    I would check the card in another machine first to be sure that isn't the card.

    If it does work then try another power supply, but get a good one like Enermax or Antec, something around 450w or better.

    I've merged your two thread into one.

    BFG have a good reputation. It unlikely to be a power issues since the 7900GT actually draws about 20W less than the 7800GT under load.

    As already mentioned, it would be useful if you could check the card in another machine.

    I checked the Dell forums and it seems that nobody has gotten one to work yet in a 8400 with the stock PSU.

    All that seems to be said is that it might work because the 7800GT etc works......

    That is guessing.
