Corsair mention on their site that their PSU's have over-voltage, under-voltage, over-current, and short circuit protection. If the actual Corsair psu fails for whatever reason, (there many be many different reasons), does that mean Corsair have protection in place to stop any damage being done to the computer components even in the event of the Corsair power supply failing? Or would there be too many different potential points of failure to get an accurate answer?

These protections lower the chance of any damage being done to your system or the power supply itself in the event of a problem.

Imagine there is an issue where a component causes a short circuit or draws too much power. The OCP would hopefully trip and stop feeding power to the system.

The problem is when a power supply fails, it is possible these protections fail aswell. They are not foolproof.
Also, sometimes these protections are set too high to allow a little wriggle room and may not trip immediatly before damage is done.

A good quality unit will have good quality components and many protections drastically reducing the likelihood of any failure.

I think this is a good question.

Power supplies can be built with no protections at all.....or they can have lots of protective features as you mention. (over-voltage, under-voltage, over-current, and short circuit protection. )

I think over-voltage protection is probably the best protection as far as protecting your components.

High voltage is the main thing that is going to fry your components.

Will these protections stop ANY damage caused by a component's own PSU failing? As far as I know.....most components don't have their own PSU. Although maybe I'm reading your question wrong.

Bottom line is.....the more protections....the better.....and generally more expensive name brand supplies like Seasonic have more of these protections built in. PLUS....they use better components.....so the likelihood of needing these protections is less.
