Had to buy the card after three delivery delays (always the evening before the delivery day...) from the competition, which delivered 18h later... Installed it and I became paler and paler... I've never heard anything like it in 30 years of PCs! Coil whine from hell! So loud that it was still audible even with relatively loud gamesound, much louder than any fan - disgusting. I've already sent emails to the supplier and Asus... nasty emails. Now today is Saturday, we try something... turns out the card hates 3 of my Corsair power supplies (hx1000i, rm750i and...) on my other PC with a Seasonic Prime tx850 power supply, the TUF 4090 OC sounds like my TUF 3080ti, inaudible while gaming. So much for the coil whine of a 4090.... Testing is easy, just put your ear to the PSU and see if the main noise isn't coming from the PSU. I would never have thought it possible...
