I'm putting together a system with an RTX 4060 Ti 16GB and a Ryzen 5 5600X, and I don't plan to overclock either component. How much wattage should I look for, and what do PSU tier lists actually tell me? I'd also like enough headroom for normal upgrades or extra fans later.

For those parts, a good-quality 650W power supply should be plenty, especially without overclocking. You can check the estimated wattage with a reputable PC power calculator, then leave some extra room for transient spikes and future upgrades. A 750W model is also reasonable if the price difference is small.
For a 4060 Ti and 5600X, 650W is a sensible target. Avoid running right at the estimated requirement because graphics cards can briefly draw more power than their average rating. Use a calculator as a starting point, add roughly 150–200W of headroom, and prioritize a reputable model with modern protections and the correct PCIe connectors.
A PSU tier list is mainly about build quality, electrical performance, protections, reliability, and sometimes warranty support. It isn’t a direct ranking of wattage. Pick a unit from a well-regarded tier with the connectors you need rather than buying the biggest unit available. Also, ‘Bronze’ refers to efficiency certification, not plating, and it doesn’t by itself tell you how reliable the PSU is.
Exactly—don’t choose based on the efficiency badge alone. A well-reviewed 80 Plus Bronze unit can be a better choice than a poorly designed Gold unit.
That’s safer than sizing the PSU around typical usage alone. The system may not need 850W, but having some reserve is useful for spikes and later upgrades.
