i know the answer for my question already
these are my computer Specs >> as shown below
i didn't check my power supply output when i had the computer
so .. i'm running it right now ( since a month ) and i haven't noticed any thing weird at all
fortunately .. i have the right to return the whole device to seller .. cauze he the one who told me that my PSU is 400 watt
but is it necessary to do that ?? i mean.. is it possible that my chips have been damaged ??
at last .. please , give your advise for a convenient PSU with the lowest budget
