I read rumours that Seasonic Tx had problems with that cards. Its ridiciolous. The most expensive model of Seasonic and issues. Read: https://www.reddit.com/r/nvidia/comments/j0t2ob/psu_concerns_with_rtx_3090/ "Linus tech tips specifically had a problem with a Seasonic TX-850W tripping its OCP at 50% power draw on the 3090, causing hard resets." So change that psu for a i dont know COrsaiR?!
