lol? The 8800 is not a monster at all, it barely draws power off the psu it draws more off the bus. You can power an 8800 off of a 350 watt power supply. Does the mother board have on board video, I assume it does if you had the option in the bios for the initial display. Plug it into the motherboard and set that as initial display. Or if you already did I guess check your other bios settings that maybe when quick boot is on you don't see the manufacturer display and boot up.
it barely draws power????? then explain why the damn card has a 6 pin that needs to be plugged in since it cant get enough power out of the bus itself. and you say it draws more from that. lmfao i cant believe i just read that.
hmm seems to me like it draws some power hey. btw the pci express slot is limited to 150 watts max draw which therefore you sir are wrong. it almost draws full power of the pci e connector at idle
here ya go look at this if you dont believe me http://www.techpowerup.com/articles/overclocking/psu/116
