Anscheinend verstößt die RX 480 gegen die offiziell zugelassenen Spezifikationen für den PCI-E Port.

Das heißt, dass die RX 480 Mainboards grillen kann aber auch, falls das Problem nicht gefixt wird,
nicht mehr als PCI-E Karte bezeichnet werden darf.

Tom's Hardware:
AMD’s Radeon RX 480 draws an average of 164W, which exceeds the company's target TDP.
And it gets worse. The load distribution works out in a way that has the card draw 86W through the motherboard’s PCIe slot.
Not only does this exceed the 75W ceiling we typically associate with a 16-lane slot, but that 75W limit covers several rails combined and not just this one interface.
We skipped long-term overclocking and overvolting tests, since the Radeon RX 480’s power consumption through the PCIe slot jumped to an average of 100W, peaking at 200W.
We just didn’t want to do that to our test platform.

With Tom's Hardware reporting that the RX 480 draws (substantailly) more than the 75W allowed from the motherboard (for example, the PCI Express high-power card spec allows a mazimum of 66W to be drawn from the 12V pins of the PCI Express slot, and the RX 480 averages 79W from the 12V lines alone) AMD seems to be violating the PCI Express(R) spec. Of course, I'd love to see HardOCP try to duplicate Tom's results.
According to the licensing contract for the spec, if they do not fix this within 3 months, AMD will NOT be able to call the card a PCI Express card. If they do, they face not only litigation, but if my understanding is correct an action before the U.S. International Trade Commission (ITC) to ban the importation of the card as counterfeit goods. You might think the PCI-SIG will give AMD a pass, but if they do, they risk loosing the trademark entirely. An unforced trademark gets invalidated. The SIG won't let that happen.
So what does this mean to the consumer? I think there are two possibilities, if we assume AMD will not choose to remove the PCI Express logos from these cards: Either they will alter the boards to have an 8-pin socket and to pull more power from there, or they will neuter the card to ensure it doesn't draw more power than the PCI Express specification allows. I don't see any other options.

Great question and I am really glad you asked.
We have extensive testing internally on our PCIE compliance and RX480 passed our testing.
However we have received feedback from some of the reviewers on high current observed on PCIE in some cases.
We are looking into these scenarios as we speak and reproduce these scenarios internally.
Our engineering team is fully engaged.
