You have a strong GPU, so it should handle your needs without needing overclocking. The note means that some high-end graphics cards can draw a lot of power, which might affect performance or cooling. Your RTX 3060 TI is well within the capabilities for most tasks.
We've all been pretty straightforward in this discussion so far, but I'm trying again. Your GPU isn't powerful enough; it's actually a lower-end model these days. Most boards don't include that extra port since most users don't require it. My 3090 draws about 350W at stock and even more when overclocked, and it doesn't have the port on my motherboard because it's not needed. The 3060Ti is a 200W card at stock.
Video cards draw energy from two main points: the PCIe port and additional connectors. They can absorb up to roughly 75 watts through the PCIe slot, or as much as 75 watts per one of the 6-pin or 8-pin PCIe connectors. All PCIe ports receive power from a 12-volt source via the 24-pin connector, which carries only two 12-volt wires—meaning the entire port can deliver about 200 watts to the motherboard. Some of this power goes to fans (motherboard headers supply 12V to fans), some powers M.2 devices, and a few might feed RGB lighting if you enable it. If three high-power cards are installed, each drawing over 60 watts from the PCIe slot, you risk exceeding the 24-pin connector’s capacity. Adding fans, extra peripherals, and other needs could push the total to 200 watts. For a single card, the limit stays at 75 watts unless you push it beyond normal operation. The 3060 Ti can use around 200 watts, sometimes briefly reaching 230 watts for a short moment. This typically results in about 50-60 watts going into the slot, with the rest coming from other connectors. If you boost the card’s performance significantly, it will still draw 50-60 watts from the slot, but more from additional cables connected to it. Excessive overclocking can increase this by another 30-50 watts overall.
