9800 Pro AIW Not booting. DFI NF2 UI + TTGI 550w PS

[LordFeaR]

Title/Summary kind of says it all..

I'm really miffed about why this 9800 Pro AIW refuses to post on my machine. I've cleared the CMOS, reseated multiple times, etc. What gives?

After some google searching, and a little info I found on ATI's site, I've discovered that the 9800 Pro has compatability issues with "a limited number" of power supplies. After googling about for a few hours, I found that it typically coincides with Antec True Power PS's, but no mention of any TTGI SuperFlower PS's. Anyone have a similar problem? Could it be an incompatability with my mobo?

Also: The card was working when pulled from an MSI KT400 Mobo w/ Enermax 420w Powersupply.

I'm gonna kick myself if it is seriously the power supply that is giving it trouble. That thing cost me quite the pretty penny a few months ago!

Any ideas greatly appreciated! Thanks.

Anyone? :<

I can hardly believe that no one has ever heard of this problem :<

Any other ideas?

I too have this problem. Antec 400sl power supply. There is another member on this site that has the same exact specs as i do, including motherboard. i have not seen a solution. I bought another power supply, still no boot. However when i unplug the vc, my monitor shows that the power is not plugged into card.
Hoping ati fixes this soon. Never had a problem with cards in past and they dont offer refunds.

Similar problem here with a 250w PSU that should be handling it. I'm curiuos what you did to resolve this.
