I'm thinking about upgrading my graphics card from a 3060 Ti to a used 3080 Ti. Currently, I'm running an AMD 7700X processor paired with a Corsair 650W Bronze power supply. I'm also planning to get a Radeon 7900 XT in the future. Do I need to upgrade my power supply to support the 3080 Ti?

Have you tried using PC Part Picker? It can give you a better idea of your system's power requirements. You might find you're on the edge, especially with power spikes. If it calculates under 600W, you might be fine, but I’d still consider upgrading if you’re serious about gaming performance.
The 30 series cards are known for their sudden spikes in power usage, so getting a new PSU would be smart. A PSU upgrade would ensure your whole setup stays stable when gaming or under load. I’d personally recommend going for at least 850W or higher.
Definitely consider getting a new PSU. The 3080 Ti is quite power-hungry compared to the 3060 Ti, and I think a good-rated PSU is essential. I also wonder if flipping straight from the 3060 Ti to the 7900 XT might be a better use of funds, since you get a larger performance boost without having to invest twice in cards.
From what I've seen, many recommend an 850W PSU when using high-end graphics cards and CPUs because the 3080 Ti can draw a lot of power, especially during peak loads. My setup runs well on a 750W Gold-rated PSU with a 5800X3D, but I wouldn't feel safe with just 650W. It really depends on how you plan to use it, but I'd upgrade for peace of mind.
You have a point about the wattage recommendations. The differences in CPUs can really impact overall draw, but even so, I agree that sticking to a higher wattage PSU is a safer bet.
Honestly, I'd skip the 3080 Ti altogether. The price-to-performance ratio seems off when you could go right for the 7900 XT for a similar price and get way better performance. Plus, if your 7900 XT pulls 580-600W at times, definitely consider a 1000W PSU instead for future-proofing. Don't settle for minor upgrades when you could jump to something better right away!
Using tools like PC Part Picker can really help clarify things. Just make sure your PSU is rated well—some Bronze models are really good for handling spikes, especially with ATX 3.0 compliance.
