Question Is there enough PCIE lanes in my cpu?

[KraKehn]

Well, I want to build a rig, in a MSI x470 with 2x RTX 3060 wich will be mining 24/7 and use my old 1050 ti just for gaming, pluged in the last pcie port of the board. The problem is that I want to use a ryzen 1500x wich has 20 pci lanes 16 for graphics and 4 for storage, and when plugging the two 3060 the motherboard automatically setts the two first x16 ports from 16 to 8x, that 16 lanes in total, the question is that, if I plug the 1050 ti in the last slot and use 4x lanes, is there going to be a problem with the cpu?, because I will be exceeding the 16 pcie lanes of the CPU.

THANKS
