I'm currently using a build with a 7600X CPU and a 3060 Ti on a 650W Gold PSU. I'm planning to upgrade to a 9800X3D CPU and an RTX 5070 GPU. My concern is whether 650W is enough to power this new combo, especially given the RTX 5070's requirements.

Definitely don’t skimp on a good PSU! The 5070 recommends a minimum of 600W, and since you’re pairing it with a 9800X3D, I'd opt for at least a 750W PSU for some extra headroom, especially if you think you might upgrade to a 5070 Ti in the future. An 850W would future-proof your system a bit more.
I'd recommend at least a 750W PSU for some breathing room. If you push your rig hard and it shuts off during gameplay, it might be time to get a new PSU!
You're likely good to go if your PSU is reputable. I use a Seasonic SGX650 with a 13600K and a 6950 XT, and it handles everything without issues—even when I overclocked! My GPU rarely exceeds 200W during gaming, so you should be alright.
You might be okay, especially if you undervolt your components. If you do face power issues down the line, you can always upgrade your PSU later on.
Your total build should be around 500W or so, so if you have a decent 650W ATX 3.x PSU, you should be fine! Just make sure it's of good quality.
