WaficLawand wroteWhat will happen to the psu if it is over over loaded? (Will you see electric sparks inside the psu or on motherboard?,will you hear a loud sound coming from psu for example?)
no there won't be any sparks flying around, when you overload a psu the output voltage will start to drop so either the psu will switch off automatically or the motherboard will do that because of lower voltage this depends on the brands, its good to mention that overloading a psu will shorten its life dramatically.
