You're assuming that both power supplies cause no damage when
they fail.  If the no name supply destroys your motherboard
or disk when it fails, then the brand name supply only has to
last a small fraction of the time to be a bargain.  Even with
a clean failure, if you put any value on having your computer
available and on the cost of your time to get a replacement
power supply and install it, the brand name supply is also
still a cheaper deal if it lasts a little while longer.
