Question about ASUS PRIME RX 9070 XT OC

Help. I have the ASUS MB TUF GAMING B850M-PLUS WIFI7 motherboard, this Rx 9070 xt and the MSI MAG A850GL PCIE5 power supply. The motherboard has 2x 8pin connectors for the cpu, 1x 24pin for the motherboard and the gpu 3x 8pin. This uses 6x 8pin on psu. I am missing 1 cable from the GPU to the PSU and I also have too few pcie connections. Have I bought the wrong power supply? Which one would work?
