I have recently moved from the US to Brazil, before I moved my computer used to work fine, now the computer won't boot, I have come to the conclusion that is my 7970's since the pc boots up fine with my old 5670, I cannot test the 7970 in any other rig since it won't fit in anything else.
My specs are:
Z77 Asus Sabertooth i7 2200k stock at 3.3 1000w OCZ PSU Radeon Diamond (2x) 13GB of RAM

And you are connecting the power from the PSU to the 7970?
Yes I am, I have researched that the wall outlet itself might not be transferring enough power to the whole computer.
