This is about drawing too much power from the Pcie slot itself.

Which is nothing new, 8800 series cards drew excessively on the pci-e slot as well and there are probably others as well.

Was it sloppy on AMD's part, though? Definitely.

I still don't get it. I mean, I read all of looniam's posts (so I have the equivalent of a minor in power connectors) but I don't understand what dictates how much power is drawn from the slot. Why doesn't it just pull 65-70W from the slot and the balance from the connector?

Read the entire piece about that in the THG review. Some of the important points may get lost in translation here.

This is news? The more definite question why is the PCI-E allowing wattage exceeding its specifications to pass through? Maybe there is a buffer, the mobo and its traces are more well made, etc = MOAR wattage!!

Like others have said - I'm pretty sure there are cards from both sides that do this.

Just more sensationalist clickbait and fearmongering.

We have the technology we do today because of standards.

Same reason why we have civilization - laws and law enforcement.

That Reddit thread is getting funnier. His new update 14 is some quote from someone on [H] that claims to be a lawyer.

"R9 380X = 200W. R9 390X=300W. Conclusion: we gotta push more watts to RX480 to make it faster"
post #89 of 1129
Props to Tomshardware for revealing this issue. I have seen people bad mouth Toms but their RX480 review was better than most of their competitors.

AMD knew about this. No way engineering could miss this. They got busted and called out.
