Inadequate PSU? Broken card? Motherboard issue?

    Just got an ATI 9800 pro to replace my GeForce 3 ti200.
    Doesn't seem to work.

    Barton 2800+ @2.2
    1 gig p3200 (unbranded, underclocked)
    Abit KX7-333R (latest BIOS)
    5 7200rpm hard drives (3 WD, 1 IBM, 1 Quantum)
    350W PSU

    Removed the old card- replaced it with the new one, IDE connector attached
    (nothing else on this line).
    Turned it on-
    Screen remains blank (orange light). Everything else responds as normal.

    It must be the PSU!
    Disconnected three HDs, the optical drive and two case fans.
    Replace ti200 -everything works fine.

    Any ideas?

    Standard questions: Did you connect the monitor to the card? Did you
    connect the extra power connector to the card? Is it seated properly?

    I think you probably need a bigger PSU, regardless. I can't believe your
    computer even functions with all those drives and such a small PSU. :)

    The KX7-333R is an AGP 2x/4x board, I think. The newer 9800 Pros are 4x/8x.
    While this SHOULDN'T cause a problem, who knows. Maybe the MB isn't coping
    with the voltage selection properly. Is there anywhere in the BIOS to
    control the AGP voltage? It should be at 1.5V.

    Could be a bad card, too.

    (replaced it with the ti200 three times- each time the ti200 works and
    the 9800 doesn't)

    I haven't even mentioned the case fans yet...
    Anyway, I disconnected all the hard drives, the DVD writer, half the
    case fans, and removed the sound card, and set the 2800 to stock speeds.
    Still no luck (tried two different IDE connectors).
    A quick google search revealed several people claming to have PCs with
    both KX7-333Rs and 9800 pros, so it might be something else.
    Will check the BIOS shortly.

    When you boot the machine with the new card do you even get to the POST
    or BIOS stage or not? Have you tried simply hitting the RESET button?
    Does that make the computer and video boot normally?

    I don't know. I think it posts, but the screen shows nothing.

    Why / how would you connect a IDE cable to it ?

    welcome to the club John, thers's lots of us out there with the same
    problen and fixes. I can get mine running with a shutdown and then
    restart (not reboot). I'm presently looking at building a delay circuit
    for the board, there's one over at that
    looks good.
    I can't believe that ATI and PSU makers haven't resolved this problem
    after all these years (Antec, my PSU maker, seems to be mentioned a lot).

    Don't some motherboard BIOSes add an extended delay in the boot to ensure
    power spikes stabilize prior to POSTing? Or is it the PSU simply
    never sends a signal to indicate it is OK (PW_OK)?

    Does hitting the reset button after the pc has been powered on for some
    time work?

    Notwithstanding your solution (why am I surprised with a Via board) ..
    you have a seriously inadequate power supply.

    Even allowing for one fan in the case and this only goes up to four
    hard drives plus a sound card .. you came out to 396 watts.

    If you have other cards in there along with the sound card start adding
    more to the table. The hard drives alone take 25 watts each (125 watts
    of your power required for them alone). The Athlon takes 69 watts and
    your Radeon 54 watts .. time for a much bigger power supply.

    Ray and John,

    If doing a restart helps (the drives are still spinning and require less
    power to speed up than when they are stopped) , then it strongly suggests a
    weak, failing, or underpowered PSU.
    Same for plugging in the power cable after the HDDs,etc are up to speed.

    Are you the same @ndrew that used to post in the Creative Labs NG? (still
    hate Asus MBs?)
