Had this 5090 for about 9 months, but it wanted to celebrate Christmas by roasting over an open fire too! And indeed it did not just melt, when I started smelling something weird, next thing I knew, it was fully on fire 🔥.
Posting here since nvidea instantly removed it over there for the statistic lol. But since people asked over there, it is a 3.1 atx psu, and yes the 12v-2×6 came with the psu. It was never used with another card, got it new for this 5090. Idk if the psu itself is great, idk much from brand to brand psu wise. PS 1050 GFM atx 3.1 version.
