If true, this could be a huge issue and may cost AMD a lot of money they don't have. I would imagine to correct the issue, they would either that to intentionally gimp the BIOS, do a recall and put an 8-pin connector on it, or something. Again, if true, this would make the 3.5GB issue the nVidia 970 had look tiny. Especially since there is a potential to cause damage to motherboards.
Uh... The motherboard connection is good for 96 watts peak with 54 sustained, if you don't have a good power supply to operate the 6-pin, you've got MAJOR issues.
An 8 pin is the same as a 6 pin with 2 more grounding wires, it doesn't supply any more power than a 6. Technically a 6 pin equipped card isn't supposed to use PCIE slot power at all. Each PCIE power cable 12v wire (of which there are ONLY EVER 3 on a connector, whether 6 or 8 pin) can handle 6amps at 12v.
EDIT: UPDATE FROM AMD:
1) The RX 480 has passed PCIe compliance testing with PCI-SIG. This is not just our internal testing. I think that should be made very clear. Obviously there are a few GPUs exhibiting anomalous behavior, and we've been in touch with these reviewers for a few days to better understand their test configurations to see how this could be possible.
2) Update #2 maybe the OP is confused. There is a difference between ASIC power, which is what ONLY THE GPU CONSUMES (110W), and total graphics power (TGP), which is what the entire graphics card uses (150W). There has been no change in the spec, so I would ask that incorrect information stop being disseminated as "fact."
We will have more on this topic soon as we investigate, but it's worth reminding people that only a very small number of hundreds of RX 480 reviews worldwide encountered this issue. Clearly that makes it aberrant, rather than the rule, and we're working to get that number down to zero.
Basically it looks like Tomshardware is using a damaged testing rig, the 80w draw on the PCIE cable is laughable... that's a single 12v wire on the 6pin's capability. It looks like they have a damaged supply or molex.
I'd place my bets on it being MSi having broken rules. Again.Edited by prjindigo - 6/29/16 at 6:12pm
