whats the deal with your power supplies.. every one I've bought has had horrible coil whine, EVGA 850 PQ,Platinum 850W is my newest psu and omg this thing screams for its life when i fold with a 2080 ti.  the EVGA 650 G1 is the only one that doesnt do it all the time, my  EVGA SuperNOVA 1200 P2 does it a little while folding, but the 850 pq does it all the time. no i dont want to rma i dont want it to cost me more money. just a valid question whats the deal.

Out of curiosity, have you used any other power supplies on that same circuit?

Coil whine can also occur dependent on power delivery to the power supply. If the power supply isn’t getting clean power, that could possibly be part of the issue.

Is there multiple items drawing power off the circuit in the your home, or is the computer on its own?

yes my old computer still crys in my bedroom when it folds like it is now lol my computer is in my living room the new one anyways

If you use a non true-sine wave UPS that can cause coil whine.

From my own experience with 780 Tis and a cheaper UPS, the power output to the PSU caused the whine. Plugging directly into the wall, and then later getting a true sine wave ups, fixed the whine.
