Or a time machine if your house is on fire.

Ive seen zero confirmed reports of damage from stock cards.

There is one very likely unrelated case of integrated audio dying. Question is, what does overdrawing power have to do with integrated audio?

we'll see about that. this seems like an issue which can cause problems/damage over time, and not instantly.

Why can't they just update the bios, so it can pull more from 6pin instead of pci-e? in my gtx670/970 it was configurable in bios. that way it won't fry mobo. 6pin can deliver more than 75w.
until now amd never cheap out like this lol.

Pulling 80w over a 66w rated rain will either cause no damage or melt a connector under load after a short while. The 12v rail on the motherboard is unregulated, there is nothing else to damage.

The BIOS does not control that. The VRM does. If three phases are connected to the slots power rail and three are connected to the PEG power connector, you cant change it in software. It will forever be a 50/50 design until there is a new board revision released.

Damn, but is configurable on 670/970 tho. hope they cancel reference design and sell AIB versions with better pcb+cooler. or that 1060 will end amd's future.

For one...

I am disappointed in AMD going off PCIe spec in terms of motherboard power delivery. This can cause issues such as popping and clicking on integrated audio solutions sharing the same PLX/PEX chip as the primary PCIe connector.

As for the claims by that (new) user on the AMD forums...

Motherboards have a single power source for all of the PCIe slots. The PCIe slots pull their power directly from the motherboards 12v delivery. If the RX480 had damaged the motherboard from pulling too much power then the system would have shut down immediately (like pulling the plug) and nothing would work anymore. You would have the same symptoms as if you tried to power on a system whose power plug was not connected to the wall. No fans would spin. No lights... nothing.

In other words... this smells of astro-turfing.

On those cards it is not quite what you think. Those are just limits that trip the throttling algos.
