Unhook your SMPS from the MB then using a digital dc volt meter. Check all voltages related .to ground .,You can turn on the supply by shorting the green wire to ground.
You may want to open it up and look for slight swelling on the ends in the secondary filter caps. CAUTION do not open it while plugged into AC wall outlit.There are 300 Volts on the Primary caps and the heatsinks
You can post the voltages on here if you would like .This is my first message I have answered. If Motherboard point sends me a reminder email I will answer you back.You can easily look up what the voltages are supposed to be. They can only be off a little tiny bit.
