I'm planning a PC upgrade that includes a new SSD, a clean Windows 10 installation, a new CPU, and a new CPU cooler. My GPU was replaced a few years ago, but most of the other components have been running on the same system for about eight years.
The power supply is a Corsair RM650x, rated at 650W and 80+ Gold, and it has worked reliably without any warning signs or stability problems. I'm considering replacing it because a failed PSU could potentially damage other components, but I also don't want to spend around $100 unnecessarily if the current unit still has plenty of life left.
Would it make sense to replace the PSU with the rest of the upgrades, or should I keep using it until I need more power or notice a problem?

Eight years is still perfectly reasonable for a well-built power supply. I’ve seen quality units run reliably for much longer. I’d replace yours when you move to a graphics card that needs more power, require newer connectors, or when a good deal on a replacement comes along.
There’s no need to replace it just because the rest of the system is being upgraded. Since it’s already a good 80+ Gold model and has been reliable, continuing to use it is reasonable as long as the total power demand stays within its limits.
