thanks for the info. i'll just order the card now and if it ends up needing more power then i'll grab that dedicated PSU.
i am running 2 10k raptors raid 0, dvd burner, with a few usb devices... so i was unsure... i think if it works, it will be close.
i was running a x800 pro but it died on me. looking for something to replace it with and cannot swing a full system to go pci-e, yet.
