It's very possible that the motherboard can have bad caps regardless of
the condition of the power supply. But in almost every computer that I
have repaired ,If the motherboard has bad caps the power supply has been
bad as well. Not a bad idea to change the power supply anyway. There
allot cheaper than mother board,cpu,hard drive etc.
