7970 has no power

[jimmyrickard]

Hey guys just picked up a gigabyte 7970 OC and upon installation it appears it's not getting any power. I previously had a 560ti which worked fine, but after installing the 7970 when I turn the computer on nothing happens. The CPU fan runs but the gfx card does nothing. I have the PCI-e 6+2 connectors in plus the other 6. I'm running a 500w seasonic psu which is apparently powerful enough.
Any ideas on what the problem could be?

Cheers

try unplug the PCIE cables and put them back, and if you have molex..try one 6pin molex with the other 6pin from your PSU

Re seat the graphics card and use two of the other six connectors to see if any of them power it up.
Also try another pci-e slot and check that the modular connector on the psu is all the way in
