Solved PSU is a parent name for smps..it is not same

Specs: Windows 7
PSU is a parent name for Power Supplie Unit.However PSU has 2 types,one is SMPS(switching) and the other is Linear Power Supplies.SMPS can switch the input voltage from high to low (act as Over Voltage Protection,OVP).However Linear Power Supplies does not.Lets say if thunder strikes your home,the high voltage will spoilt your power supplies if you use Linear power supplies.Better read more articles in the internet before your say it funny.

Why is it that people from India are so clueless when it comes to power supplies?

I don't believe I've ever seen a linear power supply used in any desktop PC - to provide the various voltages & currents involved it would have to be a fairly heavy bit of kit, so I think your point is - pointless. All PSUs used in standard computers are switching so when we refer to PSUs, there is, essentially, only one type available.

Thunder is sound. Sound will not damage your power supply.

Lightning on the other hand...

SMPS can switch the input voltage from high to low

The switching of a Switch Mode Power Supply has nothing to do with the input voltage, It switches the output voltage. Over current protection is a totally different thing altogether and can also be incorporated into a linear power supply if needed.

Early SMPS did not have over current protection and relied on the user setting the input voltage with a switch on the PSU. Get that wrong and you had problems.

Lightening can destroy a SMPS just as easily as any other kind of power supply. To protect from lightening you need a surge protector.
