I'm considering upgrading my GPU from a 3070 to a 5070 Ti. I'm wondering if I'll need to upgrade my power supply to avoid any bottleneck issues. By the way, my CPU is the 5800X3D. Any advice on this?

Yes, you will need to upgrade your PSU for the new GPU. The 5070 Ti requires more power than your current 650W unit can provide. It's not about bottlenecking, just ensuring you have enough power to run everything smoothly.
The 5800X3D has a TDP of 105W, and the 5070 Ti uses about 300W. Adding things like fans and drives, you're probably looking at over 400W total under load. Nvidia suggests a 750W PSU for stability, especially during power spikes. You could try it with your current PSU, but if it starts shutting down, that means it can't keep up. If you need to upgrade, the RM850X is a solid choice; I've had good luck with Corsair power supplies before.
