It's the one thing that is common to everything else. Most good power supplies have protection but let's say that 12 VDC rail went to 16 volts. It would turn a perfectly working puter into a nice door stop, pretty quick. It would likely burn out every component in the rig that uses the 12 volt line, which a lot of stuff does. Yea, skimping and getting a el cheapo power supply is a bad idea. Dale :-) :-)
