Non Oem 7870 in Dell XPS 8500? HELP...?

I have just bought a radeon 7870 hawk for my 8500 XPS. This is now my second doa card that I have received (The original DOA that I got 6970) Do you think that dell has a kernel built into the bios where they block the support for non oem cards. I am sure that the PSU is working properly and connected, but this seems too odd that I have received two cards that a DOA. What do you guys think?

  2. am certain that the PSU is outputting the right power because I used a multimeter, but I am checking it out tommorow with a different PSU. They put 7870 in their main desktops, but just not the hawks. I am rma'ing it, but will continue to play with it. Do u know what any of the codes in the bios are. I have tried every bios a03 through a09. I am really tired of not having working high end cards on new systems.

    It seems to come with a 460W power supply, could you look and tell us how many amps is i capable of in the +12 volt rail? There should be a sticker on the side of the power supply with the info.


    requirements for the 7870 seem to be at least 30 amps on the +12v, the 6970 would require 21 amps or better.
  4. I. Get about 29.81 amps on the multimeter. My question is how does the 6970 use more power than the 7870. The tdp of the 6970 is 240, while the 7870 is 175.
  5. It says 18, 16, and 8 on the PSU for the 12v failed. Not sure what the 8 is for.
