I recently upgraded my graphics card to an XFX Swift 9070XT from a 6600XT. The price difference between the 9070 and 9070XT was minimal, so I decided to go with the better option. My CPU is a Ryzen 5600X, which is fairly power-efficient, but I'm starting to worry about my power supply unit (PSU). My PSU is an MSI MPG A650GF from early 2022. My system includes the Ryzen 5600X (with stock cooler), 32GB DDR4 RAM, a B550 ATX motherboard, a 1TB SSD, a 4TB HDD, and 4 case fans. I'm unlikely to upgrade my PSU until next year, and I'd like to know if I should undervolt, limit the power, set FPS limits, or avoid high-demand games to keep everything running smoothly. Thanks for your advice!

You should be fine at stock settings. If you're worried, consider lowering the power limit to that of a 9070 model; that will help a lot without losing performance.
I recommend undervolting and setting a power limit for now until you can upgrade your PSU. It’s a good practice to keep things safe.
Honestly, a 650W PSU is quite sufficient for your setup. I’ve got a similar setup with a 6950XT and a 5600X3D, and I have no problems running it at stock. Just keep an eye on total power usage; I haven’t seen mine exceed 400 watts even at peak performance.
You’ll probably be just okay. Make sure to use separate PCIe cables for the card; avoid using any pigtails. If your PC shuts down during demanding games, just dial back the power limit.
Running at stock should work without issues, but I’d still encourage undervolting and applying a power limit. Keeping it under 240W during peak use is a smart move.
