by shorting the red and green pin of smps we can check it working or not
Connect Pin No. 14 & 15 on SMPS, if the fan moves then SMPS is working fine else SMPS is faulty.
If someone wants to check the voltage from SMPS even without it being connected to the motherboard that can be done by using a voltmeter. This if connected carefully can indicate the voltage.

HI This Is Adil, We can check it out in different ways.. but i know only two ways... 1. while strating up the system press the "num lock KEY" check wether its running or not then .. if its not working then its shows that SMPS is not working. 2. By removing all the connections from the motherboard and by keeping the copperwire on the 13th and 14th block (or) green and black coloured blocks, keep the wire in it if fan is running then the smps is in good condition... keep one night with out power and then use it...
SMPS are mainly 4: flyback pushpull halfbridge full bridge
You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
