If my PSU dies, can it damage other components in the process?

I'm just curious as it's getting close to 6 years old. It's a Corsair CS750M Gold, never had an issue with it but I'm worried that if it just stops working one day that it'll ruin my CPU, GPU components etc.

Depends what is the reason it dies. If by a surge, then yes that can easily kill connected parts. Leaving your network cable attached during a storm can be just as bad.

The CS is just as good as TX series so I wouldn't worry too much.

If it's a cheap PSU it definitely can. But the CS isn't one of those, should be fine.

Any PSU or part can die at any time.

[_I_]

if the psu fails on its own (failing components in the psu)
poor models can take other pc components with it
quality ones will turn off before killing components (when it reaches its limits or senses output power is out of spec)
poor psu will keep trying to power the build being very unstable, creating its own spikes on the output rails

if it dies due to outside factors (lightning, voltage spikes, ect..)
its filtering should take care of some of it, mov should clamp to force it to blow fuses/breakers

corsair psus are pretty good about dying gracefully (os/data corruption can still occur, but hardware will most likely be ok)

I had a Corsair TX650 finally tap out on me. But it served us well and was purchased in 2011 IIRC so it lasted longer then it's 7 year warranty at least and has been through many builds along the way. It just died, didn't kill anything else or anything bad. It served it's purpose and was worth it's pricing, which back then was around $110

Theoretically PSU can kill other components. Practicaly... i've seen it happen, but even with cheapest and worst psu-s one can find (those from prebuilt non-branded office systems, sometimes even without a label of any kind) it is extremely rare.
Also price/"quality" does not help as much as it might seem. Yes,expensive psu-s are built from better components etc, but any protection has limits and if something goes really wrong any power supply can kill things.
If there is some external reason, like incorrect voltage or a thunderstorm it is more likely, but unless it is direct ligtning strike into power line nearby it is still very unlikely. If you are worried about this good UPS can offer pretty good protection (but still not 100% guarantee).
