What HX1200i should I buy ?

On Corsair website there're 2 versions of HX1200i, after some researches, it seems both are internally same, the only differences are the new one has more PCIe slots, extra 12v-2x6 cable and atx 3.1 standard change some pins length

Will atx 3.1 minimize the melting risk appears on 5090 ?
