Questions about Razer Core X Chroma 2x8pin power connection cable

I just bought a Razer Core X Chroma along with an MSI RTX4060Ti GPU. MSI RTX4060Ti requires a power consumption of 550w and only one set of 8pin power connection slots. I know that Razer Core X Chroma can support up to 750w power supply, but it seems that two sets of 8pin power connections need to be inserted into the GPU. But there is only one set on my MSI GPU. So is there any other way to overcome this situation? For example, buy a Y cable as a bridge? Will this cause damage to the GPU card?
