I'd encountered this one, it happens when I connect the 3 RX480 GPUs to the motherboard, seems that the wire couldn't cope up powering up the 3 GPU's from the mainboard. I am now using powered riser to avoid that.

Yes that makes sense but it is still strange that it's been working for the last 3 months without any problems...

it was not working it was failing in slow motion.

you were most likely 100.5% of the max load on those particular wires in the 24 pin cable

when you do that you get fails in months 2-4.

been there done that.

lower clocks.
don't dual mine
use only powered risers

a little of all of the above.
