I'm considering upgrading my CPU from a 3700x to a 5700x3D while sticking with the AM4 platform. My main concern is whether my 650w power supply is sufficient, as I want to ensure I'm not hitting its limits, especially since I'm looking to achieve over 100 fps in 1440p gaming. Here's my current setup: I've got a 650w Gold Plus rated EVGA PSU that's about five years old, a GPU that's a 3080ti Founders Edition, 32GB of DDR4 RAM, and a couple of M.2 drives along with an old HDD. Will I be safe with this power supply, or should I consider an upgrade?

You'll be just fine with your setup. If you do decide to upgrade to a more powerful GPU in the future, that's where you'd want to keep an eye on the power draw.
You're totally fine with keeping your current PSU and upgrading to the 5700X3D. You'll definitely notice a performance boost!
No need to worry about upgrading the PSU for a new CPU. Your current one is still within its lifespan, and it should handle the load just fine. Just keep in mind that next time you upgrade, you might want to think about a new PSU. Old ones can sometimes fail dramatically!
The wattage increase is only about 40w, so I think your PSU is adequate for this upgrade.
The 5700X3D under PBO -30 uses around 80W. You're definitely in the clear with your current PSU!
Based on a quick wattage calculation, even with the 5700X3D upgrade, you'll be drawing less than 650w. But double-check with someone more knowledgeable if you're unsure!
