With Asrock one it was the Straight Power 11 500w 80+ Gold
GPU was RX 480 4gb with one 8 pin
Now CX650F 80+ bronze
GPU is Gtx 1070 with one 8 and one 6 pin power connector
Now and before Ive powered the system without the gpus just to clear that and under load Ive opened the case and checked precisely where the whine is coming from, and its from the vrm area of the motherboard, just before the back IO.
Sorry I didnt mention where exactly do I hear the whine.
