Have you tried the HDMI port? If none of the ports work, most likely you have a faulty card as you have plenty of power. My 7970 worked right out of the box.
Thanks for your suggestion, although there is no signal-out whatsoever, despite the fact that the card powers on fine, and spinning fans, although MOBO BIOS beeping away alerting me that there is a defective display card connected.
Seems the card has 'died' and that ASUS agrees with me that it's defective., Now, that's a real shame on something well engineered in all aspects and being my
very first ATI/AMD peripheral ever purchased!
OMG ASUS, what an embarrasment!!
I hope I get a replacement.
