Yes that's very strange. My PSU is a cheapo Itek 550w, but I don't think it's the problem, because the ASUS V9950GE FX5900 which is the very same model (not true the asus has higher memory frequency) works like a charme on the very same configuration.
Don't have that Asus card, but if for some reason it draws its power from the 12V rail instead of the 5V rail (like the A350XT), then this would certainly be a huge difference.
Anyway, as I said, it's very unlikely that this is the actual cause (typically the card just complains that it does not receive enough power), but it would definitely be good to eliminate this potential problem (and others) by going with a high quality PSU that has at least 15 - 16 amps on the 5V rail.
