Any tool is just going to blindly read the TDP, add up the TDPs, then add some wiggle room to say if it's ok or not. The 2060 has a 160w tdp, the 3060 has a 170 watt. You'll probably be fine unless you were really skimping before. Neither are particularly high power draw cards.
That said the 30 series has a reputation for really high transient spikes of power. Those spikes can easily exceed 200% of the normal power draw. If you have a high quality power supply it shouldn't be an issue. But if you skimped on the wattage and quality that could be an issue.
But if you're worried if a GPU is compatible with your motherboard then don't. PCIe is backwards and forwards compatible. Unless you're trying to run a 5090 on the first pcie board you shouldn't have any issues. And even if you did PCIe version compatibility probably aint it. It's probably only power.
