GPU Riser Power Question

Anyone have experience powering 2 risers with 1 pcie cable?

I have two 3060s on risers with their own pcie cables, but the risers are powered by one with a split.

Both cards (running at 140w on NBminer) are pulling 105-110w at the 8-pin connector according to GPU-Z, and 55-60 at PWR_SRC, so I'm assuming the power load on the one cable to the risers is fine, but I'm a bit skeptical.

House burn down or naw?
