I currently possess an x570 MSI Tomahawk equipped with a Ryzen 5 5600X. Some folks suggest you might not need the additional 4-pin connector, but I'm trying to confirm if it's still necessary based on this build. This is the latest list from PCPartPicker as of December 13, 2020.
You can check your CPU's power requirements using its specifications or manufacturer's website. The extra pin is typically needed for high-power models, not just the top-end ones.
You can look up the maximum power capacity of each connector (ATX 8-pin CPU) and then check overclocked power consumption for various boost settings. If you're not actively overclocking, focus on finding the peak draw at the chip's highest clock speed. Let me know if you need further clarification.
