I just built a core 2 duo machine with an IP35-E, E4500, ballistix x2, and the x850xt from my last computer. I'm running 1 sata hard drive and a DVD burner. It booted fine on the first try, but after that I've had a problem getting video. I got it to come back once by resetting the CMOS jumper, but that hasn't worked again.

Its working fine right now with an old PCI video card.

Is it more likely that there is a problem with the video card or that my Antec Earthwatts 430 isn't providing enough power for the video card?
 
It may be a bad PSU, bad vidcard, or a bad mobo (pci-e slot is bad or it needs bios update).

Plug the x850 back in and unplug the HDD and DVD burner, and see if you get video. If not, then its probably not the PSU. Though, do you have another PSU you could try?

Try updating the BIOS while you have the PCI card in there.

Also, could you test your x850 in another system?
 
The x850 works (as best i can tell) in my old system. The motherboard in that one is a little flaky and won't POST properly most of the time, but I get video. I'm going to try updating the BIOS now.
 
It was the power supply. I tried the video card with the 4-pin to PCI-E adapter instead of the PCI-E connector on the power supply and it worked just fine.

ps - sorry for the double post.
 
Thats weird. You think the connector is bad? Because AFAIK, those feed off the same +12V rail. The other +12V rail is for the CPU.
