Just read that original post and maaaaan are you dumb! Sorry To be fair i did that on my very first pc aswell when i was like 10. Hmm i wonder what this switch does... BANG!

I'm not surprised it's fine. PSU's have protection for this sort of thing. They'll take themselves out before your hardware.

not in a power surge if it's large enough. If a power spike overloads the PSU, all that extra voltage dumps straight into your motherboard, CPU and graphics card.

We're talking something like a lightening strike in an un-grounded environment to cause something like that to happen. Over current and over voltage protection are there for stuff just like this. They work as we can see in this scenario.

most quality PSUs do have protective circuits in them, but most PSUs I've seen that have a manual voltage switch have been awful stock PSUs, and those can cause some real damage if you overload them, and they become way less stable as time goes by. For just normal PCs with low draw, they're fine, but if you have any high-end hardware in there, chances are it will overload and blow up.

This is why 80+ standards exist, to prevent these things.

Then there's the Bestec one in my grandma's computer. No voltage switch, but it has terrible coil whine, runs hot, and sucks up way too much juice.
