Question about ASUS PRIME B450M-A II

The PRIME B450M-A II motherboard is compatible with the ASUS Dual RX 6600 V2 graphics card, as it has a PCIe 3.0 x16 slot that can support this card. However, the RX 6600 card is optimised for PCIe 4.0, which could limit its performance on this motherboard. You should also make sure that your power supply is powerful enough to support the graphics card, as it requires at least 450 watts.
