Hello good,
I have the Asus Rog RTX 3090 24Gb graphic, they change the power supply for a 1600w from corsair, before I had a 1200w and the led blinked, now with the 1600w they do not give that error, but it has a strange noise when I use the same game as It is the War Thrunder, I do not know if any of the same happens to him, I attach a video uploaded to YouTube. You have to turn up the volume, otherwise it doesn't sound well.
Greetings
