8500GT is just a 27 watter and it draws very little power in 2D mode. Even without its driver yet, PC should be able to display POST and boot to Windows. Because of their low power consumption, 8500GT and 8600GT do NOT HAVE the 6 pin PCIe connector. It is the 8600GTS and bigger cards that have the connector.

Try seating the 8500GT well on its slot. Otherwise, better test it in another PC. If it works in another PC, the card may have a slight incompatibility with your motherboards slot.

Weird. I bought a 750 watt power supply and I have a 7900 and I've never had a problem. Sounds like its drawing more power than it can produce. This can make the power supply fail, and if that happens it can take the motherboard with it. So be careful.
